Has your propane tank valve gotten stuck yet again? This can put a serious damper if you’ve planned a BBQ, or literally anything that requires your propane tank. But here’s some good news: this article will tell you exactly how to unstick a propane tank valve.

Before we move onto the meat of the matter, you need to understand how your propane tank works. This applies to anything that runs on propane: fireplaces, water heaters, stoves, gas grills, and even RVs. Knowing how your tank operates will make it easier to troubleshoot minor issues.

A basic tank is filled with propane liquid and uses a special machine that forces the propane gas into the tank under pressure, turning it into its liquid form. It remains pressurized in the tank until the valve is released. When the valve is turned, the pressure decreases and the gas converts to vapor and escapes through the opening.

The propane gas is allowed to escape the canister under a certain pressure determined by the size of the valve. Large commercial propane tanks have multiple valves and gauges.

The main valves are the fill valves to refill the tank, a service valve to release the propane, and a relief valve. The relief valve prevents too much pressure from building up in the tank and exploding.

Tanks also have gauges that measure the level of liquid in the tanks called a float gauge, as well as a vapor recovery valve that can be used to release excess vapor in the tanks when getting it serviced.

The tanks are often closed very tightly to prevent leaks. If your propane tank won’t open after you bring it home the first time, try using a wrench or a pair of pliers. You can also unhook the tank from your stove and apply a bit of oil to the valve, before trying to yank it open with pliers.

Before you try to fix a propane safety valve (or any other tank valve), you need to identify the cause of the blockage. This will determine what you need to do to correct the issue.

The most important thing to bear in mind is that propane is highly combustible. When correcting a faulty tank valve, make sure you don’t puncture the tank and cause more damage. Safety is always a priority, so work in a ventilated area and do not light matches or lighters near your tank.

Set the propane tank on a steady, level surface. Make sure you are in a dry and cool area. Carefully check the tank for any signs of obvious damage and try to find the source of any possible leaks.

Wrap the rubber band around the outer edges of the valve to get a better grip on the blocked valve. Once you get a firm grip, twist firmly to loosen and dislodge the valve with your hand.

If this doesn’t work, spray a bit of oil or lubricant on the valve. Shake the valve back and forth to loosen it up, and then try to twist it open once again.

If the valve is still stuck, use a pair of pliers or a wrench to force it open. Grasp the edge of the valve with your pliers firmly and twist counterclockwise to open the valve. Try not to use too much pressure or as this can break the valve instead.

If your valves have rust or water damage, assess the situation. If it is still in the early stages, you can use baking soda and vinegar to get rid of the rust. However, if it is too far gone, you will need to replace the valve.

To avoid the fuss of a propane tank valve that needs to be dislodged, you can follow a few simple steps to prevent it from happening in the first place.

Don’t twist the valve closed too tightly. This might sound obvious, but people tend to close the valve really tightly, especially after a refill. Shut it tight, but don’t overdo it.

After buying a new tank or refilling your old one, smack the bottom of the tank on the ground once or twice. This will loosen the valve so you can open it more easily.

Don’t open the valve of a new cylinder rapidly as this can make it get jammed the next time. Instead, test the water and work it slowly and carefully.

If your propane tank leaks when connected, you most likely need a new valve. Check for the site of the leak by spraying soapy water at the valve, connection point, and pipes. If you see bubbles at the valve or connection, the gasket is broken and the valve requires replacing.

Soak the hose for a few minutes in warm soapy water to clean it. Use grease-cutting dish soap or something similar to break down accumulated oil and debris. Rinse the hose thoroughly under running water and allow it to dry.

The propane tank shut-off valve is your best bet during leaks if the hose or valve isn’t the one behind the leaks. The service or shut-off valve is the metallic spigot-like dial located under the tank cover and hooked to the top of the tank.

You need to use this valve to turn the gas off at the tank in the event of an emergency or leak. Always turn this valve to the right (clockwise), completely to shut off the gas.

This kind of valve is required on all large 4-to-40-pound commercial cylinders in vapor service. The OPD valve is a protective device and is exactly what it sounds like. It prevents the tank from overfilling.

Place the open jaws of the crescent wrench over the large bolt of the tank’s gas regulator. This is located at the meeting point of the propane tank and the gas regulator. Use the thumbscrew to grip the jaws around the large nut.

Then, loosen the nut with the wrench. Continue to remove the nut by hand until you can pull the neck of the regulator from the propane tank connection. You may catch a small whiff of gas as the regulator’s neck is pulled from the propane tank, but this is nothing to be worried about.

Remove the tank from the grill’s cart. In some models, you might have to loosen a safety strap. Store the empty tank in a safe and dry location, outdoors and well away from any flames.

It is perfectly normal to smell a little propane as tiny amounts can leak when the tank is in use. You can also smell the gas when the tank is nearly empty.

It is common for a propane tank to hiss. Hearing this sound is an indication that your tank is leaking so shut off all the valves and check for the location of the leak.

It is always a little scary when dealing with gas tanks, as we are well aware of the risks. However, knowing how to handle any kind of malfunctioning will make it much easier to deal with.

Once you know how to unstick a propane tank valve, you can loosen the valve or spigot without any trouble. And this will make the process of grilling much easier. Happy cooking!

My understanding is the safety is in the regulator, if there is to large of a flow of gas it trips and restricts it. That is why you need to turn the tank on with the burners off. If you can"t get the appliance to work shut the tank off while the burners are on then turn them off and the regulator should reset.

I thought that is why they went to the outside threads, because the old tanks with the internal threads you could turn on and gas would flow. I was always taught to open it and close it fast to make sure any dirt got blown out. when they went to the external thread the tank won"t flow unless it is hooked up. I never investigated what is in there that the new hook up triggers to allow the gas to flow.

The propane system is often misunderstood and can be worrisome to use for some RVers. However, propane is actually one of the safest energy sources in the RV. With a basic understanding of propane operation and safety features, RVers can learn to use propane-fueled appliances with confidence.

Turn off all appliances that call for propane, including the cooktop and oven, refrigerator, water heater, and furnace. If the service valve is already in the “open” position on your propane tanks or cylinders, close it. There are arrows on the triangle-shaped handle indicating which way to turn the valves. Wait a few minutes, then turn the service valve back to the “open” position. This also resets the system if you experience a propane lockout.

Appliances operate on propane vapor. Extreme cold conditions may not allow enough vapor to be created to operate high-volume LP appliances, like the furnace. It’s best to keep the tank above half full in these situations to make sure that all appliances can operate properly.

This likely means that you’re experiencing a propane lockout and not that there is air in the lines. There’s a safety feature within your RV propane system called the excess flow valve. You can accidentally engage this safety feature, which severely “limits” the amount of propane flowing through the system. This occurs when you already have one of the propane appliances turned on prior to opening the tank’s service valve.

To reset the excess flow valve, turn off all appliances calling for propane, turn the service valve to the “closed” position, wait a couple of seconds, and turn the service valve back to the “open” position.

You can also experience a propane lockout if you attempt to unsuccessfully light an appliance three times. To reset, turn off the appliance and turn it back on to allow the 12-volt DC-powered control board to start the process again. Also, confirm that the propane tank has propane in it and that the service valve is open. If the ignition process fails repeatedly, it’s time to troubleshoot the actual appliance itself.

It’s recommended to replace a propane regulator every 5 years. There’s a rubber diaphragm inside that deteriorates over time, and temperatures also take their toll on the device. If you don’t know the age of your regulator, assume it’s expired and have it replaced.

There are tests that an RV inspector, RV technician, or propane-certified technician can perform to confirm the integrity of your regulator. Ask for an operating pressure test and a regulator lockout test.

There are three reasons why your LP detector could sound an alarm. It could be detecting propane, butane, or methane, meaning it could be detecting a propane leak within your system, or it could also be detecting butane from aerosol sprays and even methane from other sources. Another reason is that the coach battery voltage might be low. Or, the detector might be nearing the end of its life expectancy or is expired.

These troubleshooting tips can help you handle some common RV propane issues on your own. However, there are going to be problems that require the expertise of an RV technician, like replacing the regulator, leaking propane lines, and performing an annual system check-up.

Always open the propane valves SLOWLY. As was mentioned above, there are safety devices built in to limit high flows in the event of a major leak. If the valve is opened quickly the rush of propane can trigger the flow limiters.

I have even found the above to be true on some newer propane grills. My SIL has a grill that never seemed to get really hot. It would heat, but not great. I"m rarely assigned as grill master. I sometimes lose focus = burnt offerings. As an experiment I opened the propane valve slowly and then lit the grill. The burner flames were noticeably better. I closed the lid for warm up. In a short time the resulting smoke and fire was impressive. The burners had never really been hot enough to burn off the accumulating grease... at least until the valve slowly opened experiment. Anyway, the grill masters have been opening the valve slowly ever since with good results.

Do you want to know “how to tell if a propane regulator is bad in the first place?” Perhaps your propane appliances are not working properly, and you suspect that the thief is sitting inside your propane regulator.

And, you might also be wondering, what are the signs of a faulty propane regulator; how to troubleshoot propane regulator issues; and when is it time to replace a bad propane regulator?

How do we know that these questions have worried you? We receive these questions frequently from our readers, and it’s time to answer them in detail, one by one.

And by reading this article for the next 10 mins, you’ll know what to do next to come out of this distressing situation caused by a gas flow problem with your appliances. So, here we come….

There are several telltale signs of a faulty propane regulator. In the following, we’ll discuss some of the most common signs that indicate that your propane regulator is malfunctioning.

Blue flames indicate temperatures of about two thousand degrees celsius. Yellow, orange, or red flames, on the other hand, show a temperature of one thousand degrees celsius.

If the flow of propane through the regulator is proper, the gas should always burn blue. Yellow or orange flames tell us that propane pressure is low, which might be because the propane regulator fails to do the job.

If you notice soot, a black powder consisting of amorphous carbon, there might be some problem with your propane regulator. Soot appears on burners due to the incomplete combustion of hydrocarbons and doesn’t necessarily mean that the regulator is the cause behind it.

Sooty burners indicate that propane flow is being interrupted, either due to a faulty regulator or blocked hose or burners. You can troubleshoot this issue by cleaning the burners and hoses. If the issue persists, it means that the problem is with the regulator and not burners.

Unusual sounds are a common indicator that your gas regulator is underperforming. However, they’re specific too. Here is the list to tell you what kind of sound you can hear:

In ordinary conditions, burners shouldn’t make audible noises. If the burner noise is too high and causes discomfort, it’s a sure sign that the regulator is malfunctioning.

However, before replacing the regulator, make sure that all burners on your grill, stove, or fireplace make such sounds. Remember, if one of the two burners makes unusual sounds, you must understand that the problem is with the burner and not the regulator.

It’s normal for burners to hiss when on, but it’s a slight hiss instead of a roaring sound. The reason for this slight hiss is the gas flowing through the hose and burners.

High burner sounds indicate high gas pressure. If a regulator fails to mediate the high gas pressure from the propane tank, it causes the burner to roar and the flame to become inconsistent.

If your grill burners won’t light up even if you change the propane tank, it can be a faulty regulator. In most cases, it’s because the regulator’s safety feature called “bypass mode” has been activated. To resolve this issue, you’ll have toreset your gas grill regulator.

This problem happens when the regulator assumes there’s a leak in the system. You can turn off all the burners, disengage the regulator from the tank, and after waiting for at least 30 seconds, screw the regulator back to the tank.

After doing this, wait for a few seconds to let the pressure build in the hose. Then slowly turn on the burners. You’ve successfully reset your propane regulator.

The safety mechanism of the regulator consists of a valve. If there’s a low gas pressure inside the hose due to some leak, the safety valve trips, and the regulator enters bypass mode. In this case, the regulator reduces the gas flow from the propane gas tank to the burners or completely shuts down.

For the regulator to work correctly, there should be downstream gas pressure in the hose. When a gas leak occurs, the downstream pressure becomes low, causing the safety mechanism to engage. Since the regulator’s safety mechanism is delicate, it can mistakenly assume a gas leak and consequently trip.

If resetting the regulator doesn’t work, it may be that the regulator needs replacing. In this case, the regulator permanently blocks gas flow from the propane tank to the burners.

Since propane is colorless and odorless, gas companies add mercaptan (methanethiol), a foul-smelling gas that renders propane its characteristic smell. It acts as an odorant and smells like rotten garlic, cabbage, or eggs.

However, like other signs in the list, the smell of a gas leak doesn’t necessarily mean the problem is with the regulator. Sometimes, the hose that connects the regulator to the grill can also develop leaks.

To detect the point of the gas leak, you can use soapy water spray to mark the surface where bubbles develop. You can apply soapy water to the regulator to ensure that the fault is with the regulator and not with the hose.

The problem is specific to dual propane tanks regulators, commonly called two-switch regulators. The two-switch propane regulator sits between two propane tanks and automatically shifts to the other if one propane tank is empty.

If your RV or outdoor gas grill isn’t receiving propane supplies from either of the tanks, it means that the automatic changeover of your two-switch regulator isn’t functioning. Usually, in this case, you’ll have to replace your two-switch propane regulator.

A propane regulator can freeze because of liquid propane flowing out of the tank. The propane in the tank is so compressed that it becomes liquid. When propane leaves the regulator, it causes the temperature of the regulator to drop.

A slight drop in the regulator’s temperature is normal, familiar, and expected, but it becomes a problem when propane abruptly leaves the regulator, causing it to freeze.

Wondering why propane leaving out the propane tank causes the tank and regulator to freeze?It’s because when we compress a gas, we have to force gas molecules to come closer.

The compression of gas generates heat. When these gas molecules are released from the container, they produce cooling. It’s similar to saying that the energy escapes from the container, rendering the container cooler. The same principle creates cooling in refrigerators and air conditioners.

If your propane regulator freezes frequently, you don’t have to change it. The problem is usually due to container overfilling, improper positioning of the tank, or a faulty propane tank service valve. You can prevent propane regulators from freezing by placing the cylinder in an upright position.

However, there’s still a scenario that can have catastrophic results. Have you observed the phenomenon of condensation? Those tiny drops of water appearing outside an ice-filled glass?

Now, imagine a frozen regulator with a lot of humidity in the atmosphere. In this case, you can observe similar tiny drops of water on the regulator. Water vapor can also enter the regulator through vents and cause damage to the spring area and diaphragm. It, in turn, can lead to gas leaks, overpressure, or reduced gas flow into the system.

If your propane regulator has been in the water, it’s more likely that it’s permanently damaged. If water finds its way into the regulator’s spring area, it eventually leads to rusting or corrosion of the delicate metallic parts. This way, the probability of the regulator getting wholly or partially blocked increases.

If the regulator becomes blocked or clogged due to rusting, its efficiency is decreased. In this case, it won’t allow more gas to flow, limiting the gas pressure. You can’t fix a regulator that has once been submerged into the water; instead, replace it.

Propane regulators aren’t immortal; they have a service life. There’s no gold yardstick to ascertain the average service life of propane regulators, and for a good reason.

A propane regulator that comes from a reputed company can last as long as 15 years or more. If you buy one from cheap manufacturers, it’ll hardly last for a year. You can learn about the service life of your propane regulator through the documents that came along.

It’s essential to diagnose the problem first and then solve it correctly. Here are some of the crucial tests you can perform to test a propane regulator.

As already described, you can take a dish soap-water mixture in a spray bottle and apply it to the regulator, especially on the connecting points. Now turn on the gas and burners. If bubbles form, it’s where the problem lies. This test will tell you about the wear and tear of your regulator too.

One of the simplest tests is the blowing air test, just like you bowl air in a balloon. Doing it is pretty straightforward. For this purpose, you have to disconnect the gas regulator and blow air through it through a hose. On the open end, you place a candle or mud lamp to see if that air is coming through the hose to affect that burning flame.

Indeed it’s an easy way to check whether the propane regulator is clogged or not. Yet, it might not tell you the exact pressure like a pressure gauge.

If the pressure-flow readings don’t correspond to those specified by the device’s manufacturer, there can be two reasons for that. First, it may be that the regulator’s output capacity is inadequate.

In this case, you’ll need a regulator with adequate output capacity. Second, the regulator may be outdated, is malfunctioning, or is wholly or partially blocked.

A propane regulator is a device that controls the flow of gas from a propane cylinder to a propane-operated appliance. It reduces the propane tank’s high gas pressure to the much lower pressure required by the appliance.

Here are the possible reasons for a gas leak. In the case of a regulator, it happens through the vent. A regulator vent is a small, meshed opening that allows the regulator to breathe.

The regulator’s diaphragm works in conjunction with the regulator’s vent. A faulty diaphragm usually causes gas leaks. Since it’s connected to the vent, gas finds its way into the atmosphere through the vent.

Regulator vents are facing downwards to prevent water or other chemicals from falling upon them. They’re also covered in metallic mesh, further enhancing their security. However, they can catch dust, debris, and insects.

If vents are clogged due to any dust or residue, they stop communicating between the atmosphere and internal parts of the regulator. If the vent is obstructed, the regulator’s diaphragm is unable to move up and down. It can cause a gas leak, lock-up, or overpressure in the system.

Testing the propane tank regulators can be simple or complex. By conducting simple to complex tests, you can detect your gas regulator’s health and performance status.

We’ll advise you to conduct the simplest tests, e.g., of water and soap spray or blowing air through the disconnected regulator first, as mentioned above. If you find those tests not helping, then you can go for other gas pressure tests.

It shouldn’t imply that no one can clean a clogged propane regulator as a technician should be able to do this. However, propane regulators don’t cost much, and it’s better to replace a clogged regulator instead of fixing it.

Cleaning a clogged regulator isn’t worth the effort, time, and possibly money if you get it cleaned by an expert. So, it’s better to replace your underperforming, worn-out regulator for $$ than affording $$$$ damage.

Like everything on the face of the earth, propane gas regulators are also subject to entropy. They age, start malfunctioning, and come to a point where they cannot do their job.

Propane companies inform their users about the service life of their regulators, what to do if they start malfunctioning, and when it’s time to change them. The industry norm is to replace a regulator every ten years. However, if your regulator came from a cheap manufacturer, it may need replacing even sooner.

Sometimes, the problem is minor, and only a licensed mechanic can fix it. Sometimes, a regulator needs resetting because its safety mechanism has mistakenly detected a gas leak.

A failed gas regulator or automatic RV propane regulator can lead to many hazardous situations, such as a gas leak and the release of toxic gases into the environment, fire, and even a deadly explosion. For these reasons, it’s best to keep an eye on your propane gas regulator and keep in mind the signs of a faulty regulator.

A propane gas regulator is an essential part of your gas supply setup. Once gone bad, it can be hazardous. By detecting the faulty gas regulator, you can ensure the health and safety of your appliance and yourself and save your time and money. However, when finding something wrong with the regulator itself, the best practice can be to replace your propane regulator instead of looking for DIY solutions.
