Just like your home's smoke detectors' functionality should be checked, water heater manufacturers also recommend ensuring the functionality of your TPR. In manufacturers' literature or your water heater manual, this may be referred to as:

The most common cause of a leaking T&P Valve or dripping T&P Valve is an increase in thermal expansion. This is most often the result of not having a thermal expansion tank installed on your water heater's cold inlet line; if you already have a thermal expansion tank and have excessive water pressure, a technician will perform a pressure test to determine whether your T&P Valve is faulty or if you may need a Pressure Reducing Valve installed to control the water pressure in your home.

Thermal expansion refers to the process of water's volume and contained pressure increasing as a result of the water heating process.

Thermal expansion refers to the process of water's volume and contained pressure increasing as a result of the water heating process.

Hot water tankpressure relief valve

The T&P Valve is made to open by force to relieve excess temperature/pressure inside your water heater or manually during inspection. Typically, if you should lift the T&P Relief Valve handle/lever at a 90 degree angle for maintenance, you should be able to lower it back down easily into the closed position. If the T&P Valve's lever will not close fully, it will need to be replaced. This type of T&P Valve replacement will likely not be covered by the manufacturer's warranty.

If your replacement T&P Valve is not covered under warranty, you can expect to spend anywhere from about $20.00 to $75.00, depending on whether your water heater is residential (typically cheaper) or commercial (typically more expensive).

Regardless of whether you purchase your water heater at a local hardware store, from a plumbing supplier, or directly from the manufacturer, you will likely see a note in the listing and/or on the box itself that says the water heater has a pre-installed T&P Relief Valve. This means that the water heater comes with a T&P Valve that is installed in the side of the tank, however, your installer will need to add the discharge pipe. In other words, yes, your water heater has a Temperature and Pressure Relief Valve (TPR); if your tank type water heater does not have a TPR, your water heater should not be run until an appropriately sized TPR has been installed by a professional due to the potential safety risk of excessive temperature and pressure.

In some cases, T&P Valves may be faulty coming directly from the manufacturer. Permitted the technician is able to determine the T&P Valve did not fail due to: user error (i.e., being forced open), high incoming water pressure, thermal expansion, or another plumbing issue, most manufacturer warranties for labor and parts will cover the cost of the replacement T&P Relief Valve and the installation (if your water heater still has labor coverage).

Whether T&P Valve Replacement will be covered by warranty is determined by your manufacturer's warranty policy. In most cases, the water heater manufacturers will require some readings and documentation prior to approving a warranty T&P Valve replacement, including but not limited to:
