why is my propane tank leaking from safety valve supplier

Have you recently received a propane delivery? If so, an open bleeder valve or fixed liquid level gauge could be to blame. Delivery technicians open these valves during the propane refilling process and, in some cases, they are not completely closed when the refill is finished. Turn the bleeder valve clockwise until it is completely closed and you can no longer turn it. If the hissing noise persists, continue reading.

Is it a hot, sunny day? Check to see if the cap on your relief valve is open. If so, the valve is doing what it’s designed to do on hot days; slowly release pressure built up by the propane that expands when subjected to heat. The cap may have blown off due to the pressure. This safety feature is in place to protect against ruptures or explosions from expanding gas. If you see the cap open, do not look into the relief valve or tap it with anything. That can cause the valve to open all the way and release more pressure than is necessary. You can cool the tank by spraying water from your garden hose onto the tank’s surface. That should cause the relief valve to close. If the hissing noise persists, you may have a propane gas leak.

Hissing can also be a symptom of a propane gas leak. If you smell gas, immediately evacuate the area and contact Lakes Gas. If you do not smell gas and have tried both above options and still hear hissing, you can easily check for a small leak yourself by spraying a solution of dish soap and water onto the gauge or other areas of the tank where you suspect a leak. If you see bubbles, you have a leak. The larger the bubbles, the larger the size of the leak. If you do find a leak, contact Lakes Gas to arrange for repairs.

On hot days when the sun is high overhead and a propane delivery has recently been made, the safety relief valve may open slightly allowing excess pressure to vent. If the relief valve is opened, the protective cap will be removed

The following list is a starting point, but you will need to consider everything around you:Open flames: Make sure that there are no open flames, and do not flick any cigarette lighters.

Stir a cup of dishwashing liquid into a cup of warm water and pour into a spray bottle. Then simply spray around the gauges and valves of the propane tank.

After this, slowly open the cylinder valve so that a little gas comes out. If you have sprayed it with soap solution, you will see bubbles at the site of the leak.

After about 15 minutes, spray the solution again on the areas that were leaking before. Slowly turn the cylinder valve to check if there is still a leak.

If your tank is still leaking you are in danger, and need to evacuate the area. It’s important to wait until you are clear of the area and the leak before using a cellphone.

If the propane tank on your RV is leaking after a refill, then you have a serious problem on your hands. Of course, leaking propane can be extremely dangerous. So, why is your propane tank leaking after a refill?

The common reasons for a propane tank leaking are due to an open bleeder valve, an open relief valve, or a faulty valve system. We are also going to address the issue of a cracked propane tank. Although very unlikely, they can sometimes suffer serious physical damage.

Yes, absolutely is a leaking propane tank dangerous, and extremely so. Propane is flammable, which is why it is used for heating and cooking. If propane is leaking out of the tank, and it comes in contact with an open flame or spark, it’s going to cause a serious explosion.

It’s going to ignite the gas that is leaking out, and this flame will travel all the way back into the tank, and either just catch fire, or explode. There is also the fact that if it is in an enclosed space, inhaling propane is also very dangerous.

Although propane in itself is technically not toxic, it will displace the oxygen in the air. This means that if you breathe in too much propane, you won’t get enough oxygen, and can effectively suffocate to death.

One of the most common causes of a propane tank leaking after refilling is if the bleeder valve is open. Bleed valves are a special type of manually operated valve designed for bleeding liquids or gases out of a system.

It could also be the case that even if the bleeder valve is not open, the coil that it uses can be clogged with debris. This can then result in your propane tank leaking, specifically if the tank has too much propane in it. A good thing is that this is a very easy problem to solve.

The solution to a bleeder valve being open is simply to close it. All you have to do is to close the bleeder valve. You simply have to rotate the valve clockwise. Generally speaking, you are going to need to use a screwdriver, and you will need to turn the valve in a clockwise direction to close it.

The next reason why your propane tank might leak after a refill is if the relief valve is open. As the name implies, the relief valve is designed to help relieve pressure in the tank if there is too much of it.

Therefore, if it is hot outside, this relief valve may open up to allow pressure to get out of the tank. If the relief valve is slightly open, it will cause propane to leak out of the tank. Moreover, if the whole valve opens up, this can actually be quite dangerous.

the solution to a relief valve being open is actually quite simple, but you don’t actually want to touch the valve. This valve opens up all on its own in order to relieve pressure, and it should close on its own too.

If you tap or touch the valve in any way, or try to manipulate it, you may actually cause it to open up more, which is of course the opposite of what you are looking to achieve.

To solve this problem, you actually want to cool the tank down, which you can do by spraying it with some cool water or submerging it in a cold bath. This will relieve pressure on the tank and will cause the valve to close on its own.

However, if this does not work, then either this is not the issue or the relief valve is damaged to the point where you will just need to replace the propane tank.

The valve stem, or in other words the area where you connect the inlet tube to refill it with propane might be completely damaged or leaking. This is a huge problem because propane leaking out of the main stem can easily catch fire.

The solution to this issue is a little more complex because you will need to replace the entire tank valve stem system to prevent further damage and to prevent explosions from occurring.

Before you try to replace the valve, however, you need to ensure that the propane tank is 100% empty. Once the tank is 100% empty, you want to close the valve by turning the handle clockwise.

You now need to take out the leaking valve. You’re going to use a heat gun to soften up the weld that is holding together the cylinder and the gas valve.

Once this has been done, you want to open the nozzle of the tank to allow the regulator to come down to regular atmospheric pressure. You want to hold the tank very tightly while doing this.

You now need to attach the new valve and make sure that it comes complete with an overfilling prevention device inside of it. You’re going to attach the valve by threading it into the bung of the cylinder, and then tighten it using your pipe wrench.

If the actual propane cylinder itself is cracked or damaged in any way, and this is what’s causing the leak, then your only option is going to be to get a new propane tank.

If you need to replace the valve system on your propane tank, you do need to empty it first. To empty a leaking propane tank, you first want to disconnect it, and then take it to an open area.

The propane that is escaping is causing the hissing sound. Moreover, if the pressure within the propane cylinder gets to the same amount of pressure as the spring that is used to keep the relief valve shut, then the safety relief valve will open.

In other words, if your new propane tank is hissing, it is an issue with the safety relief valve. Refer to the above sections in order to fix a propane tank with an open relief valve.

When there is too much pressure inside a propane tank, the safety relief valve will open up to allow that extra pressure to escape. This is completely normal.

Propane is an extremely flammable gas, and yes, it can explode. If there is any kind of open flame or spark that the leaking propane comes into contact with, the result will be a massive explosion.

As you can see, there are a few reasons why a propane tank might leak after a refill. However, all of these issues are pretty serious, because you obviously don’t want propane leaking out.

Therefore, you want to take all of the necessary steps to remedy the issue as quickly as possible. If the propane tank cannot be fixed, you have to get a new one. Propane is just way too dangerous to take any chances with.

Propane safety is the utmost importance when it comes to propane gas leaks. If you suspect a gas leak in your home or business, stop what you’re doing, leave the area immediately, and call your propane supplier from a safe location immediately to report the leak.

Propane manufacturers add a distinctive skunk or rotten egg smell to propane so you are able to detect right away if there is a leak. Follow our steps below to keep you and your family safe in the event of a propane leak. For information on how to prevent a propane gas tank leak from happening in the first place, we recommend calling a residential propane supply company near you.

The easiest way to detect propane gas leaks is if you smell the bad odor added by the manufacturer. However, people on certain medications or the elderly may not be able to smell propane as well as others. While it’s rare, it may also be possible that the smell added by the manufacturer has dissipated due to rust inside the tank.

Checking for a propane tank leak is easy. Apply soapy water or a special leak detector solution to where the propane tank’s cylinder valve and regulator outlet connect. Next, you’ll need to slowly open the cylinder valve. Bubbles will form if there is a leak.

With any gas leak, there is always the concern that the slightest ignition could start a fire or explosion. Once a gas leak has been confirmed, you’ll need to put out any open flames. Do NOT turn on light switches, household appliances, or even use your phone. The slightest spark could cause an explosion.

If you are able to, turn the main gas supply valve clockwise to prevent more propane gas from leaking into your home. After, immediately move to a safe location and call your propane supplier.

If you are able, open as many windows as possible as you exit the house. This will help some of the built-up gas escape from your house, reducing risk of fire or explosions. Do not stop to pack any possessions. Inhaling propane gas can make breathing difficult or impossible.

Call 911 or your propane supply company as soon as you and your family are a safe distance away from the home. Your propane supplier and local fire department are able to respond to propane leaks 24/7.

Once you have evacuated the house, do not return until your local fire department has stopped the leak and deemed your home safe to re-enter. Do not be tempted to go back inside the home to get belongings. Breathing in propane gas can be deadly.

Before using any of our propane household appliances, you’ll need to schedule a propane tank inspection to ensure the leak is stopped and fixed so it won’t happen again. To prevent leaks from happening in the first place, we recommend scheduling routine propane gas tank inspections so you and your family can stay safe.

Propane tanks shouldn’t leak over time. Believe it or not, running out of gas in your propane tank can be dangerous. If the propane appliance valve or gas line of a propane tank remains open after the propane supply runs out, a leak may occur when the tank is refilled.

We advise you to leave turning on your propane tank to your propane supply company. While it’s as simple as turning a valve, there can be some significant complications with leaks from the tank to your house.

If your propane tank is leaking at the valve, call your local propane company and tell them that you have discovered a leak in your propane tank. It’s crucial that you don’t try to repair the tank any further yourself and let a professional determine a time to come to your home to do a system check or pick up the tank.

Crystal Flash is a residential propane gas supplier in Michigan that offers propane tank installation and inspection services to keep homeowners safe from gas leaks. For more information on how we protect our customers from gas leaks through propane tank maintenance services, be sure to call any of our Michigan Propane Delivery locations.

"Propane is a safe gas, but it is a flammable gas," said Don Gregory, a fire marshal with the Ozark Fire Protection District. "We want people not to have open fire or open flame near their propane tank."

"Losing a little bit of gas in order to ensure that there is proper pressure is a much safer option than having it fail." Gregory added that could mean a possible explosion if the valve fails.

"If it pops off you need to call your propane provider, put a hose on it and cool it off, they will come out and pump out gas, get it to where it is stable." Simon explained.

Using a garden hose to spray off the tank when it is really hot will cool off the tank and lower the pressure inside. You will know it is cooled off when the valve closes back up. If you have any concerns about your propane tank you should call your propane provider.

The safety relief valve is one of the most important and vital valves on any LP Gas container. All propane tanks and cylinders are required by law to be fitted with pressure relief devices designed to relieve excess pressure. The function of a safety relief valve is to keep a propane tank from rupturing in the unlikely event of excessive pressure buildup. Propane tank relief valves are also known as pop off valves, pressure venting valves or relief valves.

Relief valves are held in the closed position by the force of a powerful spring. As long as the pressure inside the tank is less than that of the spring, the valve will remain closed. If tank pressure rises to that of the spring, the valve will open resulting in a hissing sound outside the tank. If the pressure in the tank rises significantly higher than that of the spring, the valve will fully open. When the valve fully opens, it initially makes a loud pop followed by a blast of released propane gas. Once the pressure is released and the tank pressure falls below that of the spring, the valve closes.

Most propane tanks in residential and commercial service have internal safety relief valves. The reason for an internal valve as opposed to an external pressure relief valve is it presents less of an obstruction when moving the tank. Internal relief valves are generally placed near the end of the propane tank on above ground containers.

Found primarily on older tanks, external relief valves operate in the same manner as an internal relief valve with the spring mechanism being outside the propane tank itself. Relief valves on multvalves are always fitted with external safety relief valves. Older tanks with an external relief valve installed on the container are generally replaced with internal pressure relief valves, provided they are connected to a dedicated tank opening specifically designed for the placement of the relief valve.

Because the safety relief valve performs such a vital role in the protection of the propane tank, it should be maintained and repaired by licensed propane professionals only. Do not ever look into a relief valve or stand over it.

A protective cover should be placed over the relief valve to ensure proper operation. If the valve has debris in the upper mechanism of the relief valve and it opens, the debris may cause the valve to remain open resulting in a potentially dangerous situation and/or excessive loss of propane. A simple protective relief valve cover can be made from a plastic bag fastened around the external portion of the valve with a rubber band.

If a you encounter a relief valve that seems to be "hissing" (opened to relieve pressure) do not tap it or mess with it. If the tank has been recently filled in hot weather and the face gauge reads over 80 or 85%, spray some water from a hose on the tank. This may cool it down and reduce the expansion of the liquid in the tank. Call your propane company immediately and inform them of the situation.

Pictured here is a relief valve that was apparently leaking. Instead of calling the propane company to replace the valve, the customer decided to fix the problem himself. Using a soldering iron, he soldered the leak until it stopped leaking. In the process of "repairing" the leak, the customer completely sealed the relief valve in a closed position placing himself and his family in a very dangerous situation.

In this type of situation, a relief valve that is sealed shut will not allow the tank to vent excess pressure if it is overfilled or the pressure inside the tank exceeds the working pressure of the container. In a case where the tank is unable to vent to the outside, the tank is subject to rupturing causing more harm and damage than money saved by trying to fix it yourself. Let the propane company or LPG professional handle any problems with thesafety relief valve.

A new very young attendant did not release pressure prior to filling our 1988 Winnebago Itaska fixed propane tank.  My husband asked him to right at the beginning.

3 hours later and fire chief in attendance, they poured hot water over the frozen valve, to allow release, after calling for the 2nd time to the propane supplier in another city on a Saturday.

Now we"ve ordered a new tank and are having to have a major RV sales / car and truck service dealer (not Camping World) put the 31 foot rig up, and remove the tank for us.  Not sure what that will cost, but we cannot find any 5 ton jacks to borrow to do it ourselves.

Bottle jack would not lift this 11k pound Itaska high enough to get under there to undo the bolts.  And we cannot find anyone will 5 ton jacks we could use.  Suggestions welcome.

Regardless of how new your propane tank is or how often you inspect your propane system, there’s always the possibility that your tank will leak. That’s why everyone in your family needs to know what to do when it happens.

To stop a propane tank from leaking, you should first eliminate all potential igniters to minimize risks. You also need to open the windows to reduce built-up gas. Once it’s safe, you can use soap and water to find the leak. After that, you can tighten the screws and valve to stop the leak.

So, let’s go through all the steps you need to take to quickly and safely deal with it. Stick around because this article will help you gain the vital information that can keep you safe and prevent leaks from happening in the first place.

Disclaimer: propane is extremely flammable and can be dangerous. Always exercise caution and follow the manufacturer’s guidelines when working on your tank. We offer this advice with no guarantee and aren’t responsible for any mishaps!

So, if you suspect that your propane tank is leaking, you have to deal with it with urgency and care. Although it’s not advisable to fix it yourself, it doesn’t mean that you can’t do anything to stop it.

If your propane tank is leaking, you may hear a hissing sound. However, this often means that the leak is substantial, so you’d have to be more careful and act faster.

Manufacturers add an odorant to propane; it’s one of the safety features they have to help you detect a gas leak. It’ll always be a distinct smell, something you don’t normally smell inside a house, like a skunk, rotten egg, or a dead animal.

As soon as you notice any of these things, stop whatever it is you’re doing. Even the slightest spark can cause an explosion, and it won’t wait for you to finish whatever it is you’re doing. So, stop right away and do the following steps:

It’s the first thing you should do to prevent even more damages and make it easier for you to deal with the leak. You can turn off the main gas supply valve by turning the knob clockwise. If you have more than one tank, turn all of them off to minimize the risk.

Before you try anything to stop a propane tank from leaking, you must first look after your safety. So, turn off all potential igniters, including the following:

The biggest risk to any leaking tank is when there’s too much built-up gas inside the house. If the leak is substantial, you won’t be able to do anything because inhaling propane can make it difficult to breathe.

Your propane tank will have enough gas to allow you to find where the leak is coming from, but you’d have to do it as soon as possible. There are two easy ways to find leaks in your propane tank:

Once you have either of these, spray your solution around the gauges and valve of the tank. It should cover the surface to be sure that you’re finding the real problem.

Once you have your solution all over the valve and gauges, slowly open it to release some gas. Bubbles will form on the location where the leak is coming from.

Turn off the cylinder valve to stop the leak, then use a Phillips-head screwdriver to tighten the screws on the face gauge. You may also need to tighten the valve by turning it clockwise. Often, leaks come from loose screws and valves, and tightening them can save you from all the troubles of replacing your propane tank.

Leave the tank for at least 10 minutes, then spray your mixture or solution on the marked areas where the leaks were. Slowly turn on the cylinder valve and see if there are still bubbles forming in those areas.

You’ll need a professional to repair the tank or get a replacement from your dealer. Finally, don’t enter your house until a qualified professional tells you that your house is clear.

There’s very little you can do to prevent propane tanks from leaking because, in most cases, the tank is already faulty when you get it. It could also be because the tank is too old, which poses a greater risk for you.

Rusty tanks can dissipate the odorant that manufacturers add to propane, making it harder for you to detect leaks. So, be sure to check the tank that you’re using and always ask for a replacement if it looks too old.

Overfilled tanks can also be dangerous, especially when they’re in storage. So, as soon as you get a propane tank, be sure to find the tare weight (TW) printed anywhere on the tank. TW is the tank’s weight when empty.

Weigh the tank, then subtract the TW to give you the weight of the propane inside it. If it’s more than what the tank can safely hold, then it’s overweight, and you’d have to release some of it.

Finally, you should get a qualified professional to conduct regular inspection of your propane system. Doing so will help you identify potential issues and ensure that you won’t have leakage problems in the future.

A leaking propane tank is very dangerous, and you have to act as soon as you suspect there’s a leak. Manufacturers add an odorant to propane, making it easier for you to detect leaks and take the necessary steps to keep you and your family safe.

Using a mixture of soap and water, you can easily detect where the leak is coming from, allowing you to stop it. If tightening the screws and valve doesn’t work, it would be best to call a professional to help you repair or replace your propane tank and clear the gas inside your house.

If you’ve ever hooked up a new propane gas tank and heard a faint hissing sound, your first thought is likely to be, uh oh—there’s a gas leak somewhere. Well, this may be true. Propane tanks will often hint at a slight leak by making a hissing sound, which gets louder as you get closer to the tank. But, there are a few other possible reasons your new tank isn’t working as expected. So next time you hear the hissing and suspect you might have a leaking propane tank on your hands, follow these tips to determine the cause.

If you hear a hissing noise,tune into your sense of smell too. If you smell gas, and you’ve checked the situation is safe, turn the cylinder valve clockwise to the off position. If you are unable to turn it off, leave the area and call your local fire department. In both cases, you’ll need to have a qualified service technician check out your grill for leaks. Generally, a humming sound without the smell of gas is normal.

If you suspect there may be a gas leak from the hose or connectors, and it is safe to do so, you can use a simple test to determine the leak. Prepare a solution of equal parts water and liquid dish soap. Ensure the cylinder valve on the gas tank is closed. Either pour into a spray bottle or use a grilling brush to apply the solution along the gas hose and connections. Open the cylinder valve, and examine the hose and gas line connections for soap bubbles. These bubbles indicate a leak. If you see bubbles, turn off the cylinder valve and replace or repair the area that is leaking by contacting a qualified service technician.

The bleeder valve, also called a fixed liquid level gauge, is typically opened by the delivery person when a tank is filled with propane. If the bleeder valve is not closed entirely, or was blocked from the inside when closed but is now cleared, this may be causing the noise. To fix this, turn the bleeder valve clockwise to ensure it is closed and stop the flow of gas.

Propane tanks can build up extra pressure when they overheat due to expanding liquid in the tank. On extra hot days, the safety relief valve may open to release built up pressure in the tank. The pressure will remove the protective cap, opening the relief valve. It is crucial to not look into the relief valve or tap it with anything. You want to avoid the relief valve opening all the way. The easiest fix is to spray to tank with a water hose to cool it down, causing the relief valve to close entirely.

To set up your propane tank, remove the grill cover entirely and position grill away from flammable materials. Make sure the gas is turned off and the used tank has been removed. Turn the service valve hand wheel to the right so it is turned off, and remove the plastic cap covering the nozzle. Snuggly connect the grill’s gas line to the nozzle, and turn the coupler to the right until everything is screwed in completely. Turn the gas valve on the propane tank to open.

Always keep flammable and combustible materials (e.g., paper, clothing, wood, gasoline, solvents) away from any open flames that originate from your appliances.

Never place your head near or directly over the valves on your storage tank. A sudden release of product from the safety relief valve could result in serious injury.

If you think you smell propane in your home, camper, RV or the area around any gas equipment, or if a gas alarm signals the presence of propane, you should IMMEDIATELY follow these suggestions:

Even if you do not continue to smell propane, do not open or turn on the propane supply valve. Do not re-enter the building, vehicle or area. Let a qualified propane service technician and/or emergency personnel check for escaped propane.

Have a properly trained propane service technician repair the leak. The propane service technician or emergency responder needs to determine that the leak situation has been fully resolved. The propane service technician should check all of your gas appliances and re-light any appliance pilots.

All lines not attached to appliances must be closed and terminated with threaded caps or plugs. If you have any questions, please call your propane supplier.

Propane expands when heated. That increases the pressure in the tank. Above a certain pressure, the relief valve opens to release a small amount of vapor. That release keeps the pressure from building up too much inside the tank. Once excess pressure has been released, the relief valve closes automatically.

It’s important to keep your tank painted with a white, aluminum or other reflective color. A rusty, unpainted or dark-colored tank may cause pressure build-up resulting in a safety relief valve discharge.

All appliances should be installed and repaired only by qualified technicians. Improper ventilation can starve the combustion process in the appliance and create a situation that could produce toxic carbon monoxide gas. Carbon monoxide is an odorless and colorless gas that, in sufficient amounts, may be deadly to humans. Usually, headaches and/or flu-like systems are initial signs of carbon monoxide poisoning. If you suspect that any of your appliances have been improperly vented, you should discontinue using them and contact your propane supplier or local fire department immediately for an inspection.

An appliance gas control is a precision mechanism that may malfunction if it is exposed to water from flooding, storms, or any other damaging environments. A flooded gas control must be replaced by a qualified gas appliance technician. Damaged gas control valves must be replaced.

If you continue to smell gas, even after lighting a pilot, turn off the gas valve immediately upstream of the appliance to stop the flow of gas. Contact your propane supplier immediately to investigate the situation.

If an appliance or any other component of your propane system has been tagged “out-of-service,” do not attempt to enable it. The tag indicates a serious unsafe condition.

Ask your propane supplier to conduct a regular gas safety check to inspect your system for leaks and ensure it meets all applicable safety standards. The technician will also check your tank, piping, regulators, gauges, connectors, valves, vents, thermostats, pilots, burners and appliance controls to make sure they are in good working condition.

Do not use a propane gas cylinder if it shows signs of external damage, such as dents, gouges, bulges, fire damage, corrosion, leakage or excessive rust.

To see how much propane is left in your cylinder, run a wet finger down the side. The wet streak will evaporate faster over the empty part of the cylinder.
