Pressure Relief Valve Wow

The water heater is one of the most essential appliances in any household. Nothing brings more relief than being able to soak in the hot shower at the end of the day. It is why ensuring that the water heater remains in good condition is so vital. If you face any issues, it is better to call in the experts immediately. If you delay it, you might unintentionally worsen the damage. Most of the time, the issue lies with the pressure relief valve.

What is the pressure relief valve?

The pressure relief valve, also known as the temperature and pressure relief valve, is a critical component of the water heater. When the temperature and pressure inside the tank rise to extreme heights, the valve opens. It is due to this opening that the steam escapes, and you remain safe from a possible explosion. Therein lies the most advantageous aspect of the valve.

How does the pressure relief valve work?

In order to prevent any damage to the home, it is vital that you know the functioning of the relief valve. A water heater is essentially a closed system, and as such thermal expansion is common.

Most of the water heaters are either powered by gas or electricity. In each case, when the temperature of the water within the tank reaches 120-140 degrees Fahrenheit, expansion of the water, as well as the tank, occurs.

A certain degree of expansion is considered normal. However, when the pressure escalates to 150 psi or the temperature climbs to 210 degrees, the valve opens. It then expels the steam and hot water via the discharge tube and keeps the device safe from any explosions.

Tips to check the pressure relief valve of the water heater

There are multiple ways that you can ensure that the pressure relief valve is functioning properly. The manufacturers usually recommend checking at regular intervals to prevent massive damage. Check out the tips listed to gain more knowledge.

  1. Firstly, ensure that the discharge tube of the water heater remains attached. Wear protective gear to prevent any possible damage to your body.
  2. Then, put a bucket beneath the discharge tube.
  3. Now, you must pull the lever of the pressure relief valve. It will cause water to flow into the bucket below.
  4. After that, allow the lever to go back into its original place. But, if the lever is unable to move, then you have a faulty valve at your hand. It will need immediate attention.

Different issues with the relief valve

There are various issues that can occur related to the pressure relief valve. However, the most common reasons are the valve remains open and the leakage of the valve.

Another issue that you can come across is that the valve becomes stuck in different positions. If it gets stuck in the extended position, then it can cause water leakage. It will happen via the discharge tube and can lead to potential flooding of the house. However, if the valve gets stuck in the downward position, then it can cause a rupture of the tank.
