If a water pressure issue is what is causing the water heater pressure relief valve to not work, then it might be dangerous for you to change the valve yourself. Generally speaking, it’s a good idea to hire a professional to protect yourself.

Fortunately, by understanding how relief valves work, you can solve whatever problem you’re having with the one on your water heater. In this article, we’ll review everything you should know about this valve.

Regulating valve

When your water heater pressure relief valve isn’t functioning properly, it’s usually for one of two reasons. It either sticks so that it doesn’t properly open or close, or it has a leak, which means that it’s continually dripping, lowering your water pressure.

If you’ve been noticing any issues with your water heater pressure relief valve, then you need to know where it is on your water heater. Usually, you can find it on the top or side of this appliance. The valve connects to a plastic or metal discharge tube that runs down the side of the tank.

If you’ve been having issues with your water heater recently, this article is for you! You might find that you’re paying high energy bills, not getting access to hot water when you want it, or your water pressure is low. This can be frustrating, but what’s the cause? You might be having a problem with the water heater pressure relief valve.

It’s important to maintain the correct pressure in a hot water heater for efficient performance and safety. But what happens when the pressure gets too […]

A water heater pressure relief valve, also referred to as a T&P valve, or water heater temperature valve is a safety feature that you can find on all water heaters. The reason it’s there is to keep you safe in case the water pressure gets too high.

However, when the temperature is 210 degrees—or the pressure is 150 psi (pounds per square inch)—t his is far too much pressure and heat in the water heater tank. If it’s the case, you should change your hot water heater temperature or verify your heater thermostat.

Finally, release the level so that it quickly snaps into the original position. If it doesn’t snap quickly into this original position, then your water heater valve isn’t working and needs to be replaced.

Cash Acme has been manufacturing state-of-the-art PRV valves for over 100 years. With over 150 water pressure reducing valve sizes and configurations, our inventory of water pressure regulators is more than capable of handling your commercial, residential and even agricultural product needs.

If you suspect there’s a problem with your water heater pressure relief valve, you can do a test. This is actually a good idea if you don’t have any problems at all, as this type of maintenance will protect your water heater—and yourself.

Sometimes, you can easily fix this problem by opening and closing the valve lever a few times. However, if it continues to stick, then you’ll need to replace it.

To get started, identify where the relief valve shut off is. Usually, you can find it upon the cold water feed, which is on top of the water tank, on the right side where the inlet is.

Your water heater is leaking? Make sure that it doesn’t come from the valve before replacing it. If your pressure relief valve is leaking, then this may be because it isn’t seated properly in the tank’s threaded opening. This is quite a common issue if you’ve recently replaced your old valve with a new one.

Once you’ve done this, take a look at the discharge tube to make sure that it’s attached firmly. Then, take a bucket and put it under the discharge tube.

This said, considering that there might be other issues causing discharge tube problems—issues connected to high water pressure or temperature—it’s safest to have a professional deal with this too.

A water heater pressure relief valve, also referred to as a T&P valve, pressure relief valve, or water heater temperature valve is a safety feature that you can find on any water heater. The reason it’s there is to keep you safe in case the water pressure is too high.

Pressure regulating or reducing valves (PRVs) help control downstream water pressure in commercial and residential systems. Each water pressure regulating valve is tested for quality and efficiency before leaving our factory so you know it’s reliable under pressure. Plus, a number of our PRVs are designed with SharkBite connectors to simplify installations and repairs.

To avoid draining the hot water heater or replacing the valve every so often, install the Corro-Protec powered anode to solve those two issues.

This said, if you’re only having issues with the discharge tube, this is easy to replace. You won’t have to drain your water heater, and you can deal with it yourself.

This valve also ensures that there aren’t any leaks in your water heater, which would lead to low water pressure when you want to use it to wash the dishes or take a shower.

If your valve is working, this is when it will open. This releases steam and hot water from the discharge tube, making your water heater operate safely again.

The water heater pressure is already installed when you receive your water heater (or buy a home that has one already). It’s actually welded onto the tank; you’ll see a threaded inlet where it is.

This is for safety reasons. Everything has been done according to standards that have been mandated by plumbing codes. So if you’re having any issues with the valve, you’ll have to call a professional to have it fixed.

Most Cash Acme water pressure regulators come preset at 45psi but can be adjusted within a specific range depending on the model. As the downstream water pressure approaches the set pressure, the valve will close off, not allowing water to pass through. As that downstream water pressure drops, typically due to water usage, the pressure regulator will open back up letting water through to recharge the system as long as the demand is needed.

Without this safety feature, your water heater could end up breaking. You could potentially end up with burns if the high water pressure is dangerously high.

The water heater pressure valve is in place so that it can relieve excess pressure and temperature in a water heater if either of these is too high. Because this everyday appliance is a closed system, thermal expansion occurs in water heaters.

Now, pull the metal lever of the valve slightly, so that a small amount of the water—a quarter cup or so—discharges into the bucket.

If your valve is sticky, then it becomes stuck in a closed (downward) or open (extended position). If it’s closed, then the valve won’t be able to relieve the heat or pressure that builds up in the closed water heater system. There could be a rupture as a result.

Here’s how it works. Whether your water heater is heated by electric heating elements or a gas burner, both the metal tank and the water inside expand when the hot water temperature is somewhere between 120 and 140 degrees.
