Does pressure relief valve need pipe?
The Temperature & Pressure Relief Valve or TPR Valve on any heated appliance that contains water, such as a heating boiler, hot water tank, water heater, water cylinder, must have a drain line or discharge tube properly installed, routed, and made of proper materials.
Where should pressure relief valve drain to?
The valve should be connected to a discharge pipe (also called a drain line) that runs down the length of the water heater tank. This pipe is responsible for routing hot water released from the TPR to a proper discharge location.
Why is my water heater leaking from the overflow pipe?
A leaking overflow pipe can indicate that: The temperature setting on your water heater is too high. There is an issue inside your tank causing pressure to increase beyond the T&P valves threshold. The T&P valve is not “set” properly allowign the valve to remain partially open.
What type of pipe is used for hot water heater?
CPVC pipes are an ideal choice for hot water plumbing. They are made after adding material that goes through extra chlorination process which gives CPVC higher quality.
Where does water heater pressure relief valve go?
How to Find the Water Heater Pressure Relief Valve. Also known as the temperature/pressure relief valve, or the TPR valve, this valve is located near the top of the water heater. It usually features a lever you can lift up or down and has a discharge pipe that runs from the valve down to the water heater’s base.
Why is my hot water heater leaking from the pressure relief valve?
Your water heater’s relief valve can start leaking for one of two reasons: either the valve was triggered to open because of excessive temperature or pressure, or the valve itself is faulty. In the first case, the valve will drain water out of the discharge pipe as explained above.

What’s the difference between red and blue PEX pipe?
Although there are three types of PEX (see Label Lingo, below), the different colors don’t connote the distinctions; they simply make it easy for the installer to identify which lines carry hot water and which carry cold. Red PEX pipe carries hot water. Blue PEX pipe carries cold water.
What size pipe goes into water heater?

There’s a problem with the valve, such as a faulty seal, and the water is unintentionally leaking.
