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.

Here's What Our Customers Are Saying About Us.
This afternoon we found a leak after disconnecting our refrigerator. We called A.M. Plumbing. Their response time was excellent. They arrived to our house within an hour after calling them. When the plumber got to the house, he was able to rapidly diagnose and fix the problem. He was very professional, did a great job and they charged us a very reasonable fee. I would recommend A.M. Plumbing to anyone that needs plumbing repairs. Thank you, again, for a job well done!
I have called A.M. plumbing twice. Both times the service was excellent. He was able to talk to me about the problem and offer his recommendations. I found him to be trustworthy and reliable, which is what I am looking for in a plumber. I would highly recommend A.M.Dan Steele
Alex and his team are by far the easiest to work with! From the time I spoke with Kristen(sp?) to the time the job was complete they spoke to me like a person and not like I'm an idiot. I had a whole house repipe and an awesome never run out of hot water tankless water heater installed. They were professional and cleaned up after themselves. So glad to have found them on here and will be sure to pass along my experience with them to others. Thank you Alex and the team at AM, our family of 5 can finally have hot showers again!!
