The Role of the Temperature and Pressure Relief Valve

Your water heater works nonstop to meet your hot water needs. However, like any other appliance, it can malfunction due to wear and tear and cause harm to your household. That’s where the temperature and pressure relief valve (T&P valve) comes into play. A.M. Plumbing & Rooter discusses what a T&P valve is and why it’s an essential safety feature in a hot water heater.

What is a Temperature and Pressure Relief Valve?

A T&P valve is a safety component that releases excess temperature and pressure that could build up in the water heater tank. It’s a small valve with a metal lever and a discharge pipe that extends from the water heater installation to the floor or outside your home.

The valve opens when the water temperature or pressure exceeds a pre-determined level, allowing hot water to escape and prevent the tank from rupturing. This component is crucial in preventing an emergency water heater repair in Fallbrook, CA.

Importance of the T&P Valve

The T&P valve is so significant that we put it on top of our checklist whenever we conduct preventive water heater services. Here are the reasons it’s essential:

• Prevents Overpressure – It protects the tank and the surrounding area from water damage. Furthermore, it reduces the risk of scalding.

• Prevents Overheating – It prevents your water heater from overheating. In turn, it steers clear of fire hazards and damage to the tank, prolonging the service of your unit.

• Meets Safety Standards – Building codes require installing a T&P valve to minimize the risks of plumbing emergencies.

How to Maintain the T&P Valve

If you notice that water is leaking from the T&P valve, have a professional fix it immediately to avoid further damage. A malfunctioning T&P valve may be caused by corrosion and mineral buildup.

We recommend inspecting the T&P valve regularly. Lift the valve to ensure it releases water via the discharge pipe. Note that the water in the tank is hot, so clear the area surrounding the tank and let the water discharge properly. If water flows through the pipe, it means your valve is in good working order.
