coffee percolator safety valve for sale
The devil is in the details. It is often the smallest things, the particularities, that make all the difference. This is also the case in regards to the preparation of a good coffee, a ritual in which all the steps and every single component play a fundamental role. Among all, one of the most important elements is the Moka valve. Often ignored, it is vital not only for the quality of the coffee, but also for the safety of those who prepare it.
The valve was born with the invention of the Moka Express in 1933. It is a safety valve positioned on the bottom chamber. To better understand the importance of the valve and its use, we need to take a step back and illustrate step by step
This is where the valve of the Moka comes into play. It must open when the pressure is too high. By doing so, it allows the steam to escape regularly, without causing any damage. In short, the Moka’s safety valve provides security. Hence, it should only intervene when the coffee maker is used under abnormal operating conditions.
A long-standing and debated question: how far can you fill the bottom chamber for a state-of-the-art coffee? The Moka valve can come in handy to answer this dilemma. Another important role of the valve is that it acts as a "measuring cup". Its position on the bottom chamber is not accidental. Rather, it indicates to those who prepare the coffee the correct amount of water to use. The only exception is for some special coffee pots that are already equipped with a measuring cup. Ideally the water should reach just below the safety valve.
By contrast, if you drown it completely, there is a risk that it will not work properly. Moreover, if the water goes beyond the filter, thus mixing with the grounds, it would hinder the gradual rise of the water, compromising the final result. Be that as it may, once the coffee has been prepared, it is normal that a small amount of water remains inside the bottom chamber.
The Moka valve, therefore, is not a decoration or a mere design element. Rather, it is a very important component for the correct functioning of the coffee maker. It guarantees safety and plays a part in the making of an excellent coffee.
Consequently, it is necessary to keep it clean and maintain it regularly. For example, using tap water to make coffee brings with it the risk of limescale deposits obstructing the hole in the valve. The resulting danger is that it could get clogged.
We have seen that one can simply use hot water to clean the Moka valve. To avoid limescale obstructions, simply move the piston that comes out of the valve along its axis when washing it. To ensure the Moka functions correctly, it is recommended to repeat this checkup periodically.

While both coffee-brewing methods rely on pressure, espresso occurs somewhere between five and 10 bars of pressure (depending on whom you ask) and the pressure a Moka pot achieves is, optimally, somewhere between one and one-and-a-half bars of pressure.
Because of this, the grind size for Moka pots is typically a little coarser, and, according to Matteo D"Ottavio, the 2020 UK Brewers Cup Champion, should be between espresso (very fine) and drip coffee (medium-fine) grounds. He wouldn"t give us a particular size, but we find somewhere around 500 microns will do the trick with a medium-roast coffee. Along with D"Ottavio, we also recommend you go up in size for dark roast and down in size for light roast.
Sorry, I wasn"t clear. I mean the pressure relief valve that is screwed into the side of the lower chamber. On all of my moka pots, this valve now leaks, so the pot never builds sufficient pressure to function.
I found a similar but slightly larger valve at MSC online, and was able to drill out and re-tap the hole in one of my aluminium moka pots to fit this valve with an o-ring. So that one is repaired. However, drilling out and retapping my stainless steel moka pots will be harder, and I am hoping to find the correct valve as used by Bialetti.
Edit: the valve I found is this one https://www.mscdirect.com/product/details/03244811 1/8" thread, 15-25 psi, $2.44. But it isn"t quite the correct thread to replace the original valve.
Have you noticed water coming out of your Moka pot? It"s probably an easy fix, like washing away all the loose coffee grounds. If you ignore it, the problem may worsen, and you might even have to buy a new Moka pot. Read this article to find out how to fix a Moka pot leak.
There are a few reasons why a stovetop espresso maker could leak. This could be because of poor maintenance, worn-off seals, poor design, or simply loose coffee grounds at the start of the brewing process. Let"s look into the main reasons for water leaks in a stovetop coffee maker.
The first thing you need to do if you have a leaky coffee maker is to find out where the leak is coming from. To do that, you"ll have to see if it"s a coffee leak or a water leak. If it"s a coffee leak, you"ll probably have to be looking at the upper part of the stovetop espresso maker.
This is where most leaks happen. The connection between the two coffee pot chambers and the filter basket is where the rubber seals are, and that"s where the problems may be. Let"s look into what you can try.
Another very easy fix. When you"re putting the Moka pot together to start brewing a cup of coffee, you need to make sure you"re putting the rubber gasket where it"s supposed to be. This means that you have to put the coffee pot together as follows:
To keep the thread on your Moka pot safe from harm, ensure that both sides are clean, and there are no loose coffee grounds on either. Additionally, you want to ensure you"re not over-tightening the two ports, especially on an aluminum pot.
If water comes out of your pot"s safety valve, the good news is that it"s probably fixable. The bad news, though, is that it will take some time to fix it.
If there"s a jet shooting out of your pot"s pressure valve, it could be because of too much water. You"ll want to always pour water into the bottom edge of the safety valve.
The most common reasons for safety valve leaks are coffee residue and limescale buildup. This may be why the valve may be opening or closing incorrectly.
I. The easiest fix is to push the valve closed (or open). If there isn"t too much buildup or it"s not completely dry, this may push some of the buildup away and let the valve move freely.
Now, even this may not fix the leaks. If your Moka pot is old, the valve might have worn out. Inside there"s a small rubber ring that will harden and eventually break over time. If that happens, water may be leaking out of there.
For some high-end pots, you can simply buy a replacement pressure valve. You"ll have to make sure ordering the new part and paying for shipment is less expensive than getting a new pot, though.
It"s crucial that you wash your Moka pot after each use. You"ll want to ensure there are no loose coffee grounds or leftover coffee in the lower and upper chambers and the filter basket.
If you don"t clean your pot regularly, coffee and probably limescale will build up and gradually ruin your stovetop espresso maker. Even if that doesn"t happen, the taste of your brew will slowly deteriorate.
We recommend doing this if you live in an area with hard water. Hard water may be the reason for mineral deposits to build up and lead to a coffee maker leak.
It"s a good idea to check the pressure release valve of the pot works properly between brews. It"s there to release the excessive pressure out of the pot, and if it"s not working properly, your coffee maker might leak or even explode.
Even though Moka pots are simple coffee makers, you should still take care of them with each brew. If your stovetop espresso maker is made of high-quality materials and you take good care of it, it"ll last you for years. Get yourhigh-quality stainless steel Moka potnow.
