If you replace a TPRV and it starts leaking again, it probably means the valve is doing its job; it’s relieving excess pressure.

Why is the pressure relief valve leaking on a new water heater?

A leaking temperature pressure relief valve isn’t necessarily faulty. These valves are designed to open up if the temperature inside the tank is too hot or the pressure goes over 150 PSI. So it could just be leaking because of too much pressure in the tank.

Is it normal for pressure relief valve to drip?

You are at risk of the tank bursting and flooding your home. It’s quite common for water to be dripping from the temperature-pressure relief valve, which is designed to release water when it senses too much pressure.

Why is my brand new hot water heater leaking?

A: Water heaters can leak due to a number of problems, including loose valves, excessive pressure in the tank, or issues with the pipes that connect to the unit. And if your water heater is more than 10 years old, the leak is likely age-related—if that’s the case, it may be time to replace it.

How much should a TPR valve leak?

You should expect the pressure to be somewhere in the 40 – 80 psi range, with no other water running. If the pressure is over 80 psi, it should be corrected. The solution is to have a pressure regulator installed. Get a plumber to do that.

How do I fix a leaking pressure relief valve?

Use a pipe wrench to unscrew the old pressure relief valve. Wrap Teflon tape around the threads of the new valve, and screw it in until tight, orienting the overflow pipe opening away from the tank. Reattach the relief valve drain pipe using Teflon tape on the threads.

How do you fix a TPR valve?

First, replace the TPR valve

Cut the overflow tube on a top-mount TPR with a hacksaw. Then unscrew the threaded fitting from the old TPR valve and install the new valve. Reattach the overflow tube by soldering in a coupler, or use a push-on connector.

What causes too much pressure in hot water heater?

In short, when the temperature or pressure of the water heater gets too high, the valve opens, and releases water that’s causing the increase in pressure. The problem is that many homeowners don’t realize they need to be testing their T&P valves every 6 months, and replacing them every 5 years.
