Water Heater T&P Valve Drain Line


Water Heater T&P Valve Drain Line. The last line of defense for pressurized equipment, temperature and pressure (t&p) relief valves are critical safety devices that protect equipment from excess pressure and, ultimately, catastrophic failure. Tpr valves prevent water heaters from exploding.

House is on a slab. Close the t&p valve and the drain valve. Majority of water heater are located where the relief line has no option other than going up and then to outside wall where it drops to go outside at a safe height low off the ground.

This Pipe Is Responsible For Routing Hot Water.


If the temperature rises above 210 degrees fahrenheit or the pressure exceeds 150 psi, the valve will open and relieve the pressure inside the tank. I would like to install a drain pan under the water heater. Pex tubing can be used up to 200° fahrenheit for heating applications.

If You Have An Electric Heater, Turn The Main Power Back On.


Current water heater has a 3/4 copper tube soldered to the valve and running down the side of the heater. The safety pan cannot connect directly to a live drain line. However this requires a drain by the water heater at the lowest point before rising up.

Jiggle The T&P Valve By Gently Pulling The Lever Towards You.


I am wondering about the best method to route the drain line attached to the temp&press relief valve in my water heater. House is on a slab. It is the water heater’s failsafe.

They Are Designed To Provide An Emergency Outlet, Safely Discharging Pressure In The Event Of Problems With Your Water Heater.


Disconnect the discharge tube from the valve using a wrench. The pressure relief setting of the t&p would have to be lower than the operating pressure of. Most t&p valves relieve at 150 psi.

If You Have A Gas Heater, Relight The Burner.


I want to cut my relief discharge line and install a tee in order to connect my drain pan's line and allow both to exit using the existing pipe. The valve should be connected to a discharge pipe (also called a drain line) that runs down the length of the water heater tank. Currently, i only have a t&p relief discharge line that runs down to just above the pedestal and out through the exterior wall.
