Water Heater T P Discharge Line

Make sure that the discharge tube is firmly attached.

Water heater t p discharge line.

Temperature pressure relief valve discharge tubes drain lines their piping. The watts 210 shuts off the gas it the temperture is in excessive. I did a little research and quickly discovered that this issue needs much more discussion than is. Scalding water and steam escape the tank through the valve and tube to relieve the pressure.

Water heater manufacturers recommend regular checking of the t p valve. The valve should be connected to a discharge pipe also called a drain line that runs down the length of the water heater tank. The temperture sensing bulb of the valve goes in the upper portion of the tank and the gas piping runs through the valve. Briefly pull back on the t p valve s metal lever to cause a small amount of water about.

If there is no discharge line connected to the t p valve and it opens up those near the water heater may suffer 1st 2nd or 3rd degree burns. 8 termination of the tpr drain pipe cannot be more than 6 inches or less than two pipe diameters above the floor ground or waster receptor flood rim level. 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. Place a bucket below the discharge tube.

Building codes require temperature pressure relief tpr valves with discharge pipes on all new water heater installations. When the water heater is in a basement or below grade it may not be possible to arrange for a gravity drain of the tprv. This relieves the high water pressure and prevents the water heater from rupturing or exploding. A few installers have raised a question about the discharge pipe for the water heater temperature and pressure t p relief valve.

Wear closed toe shoes to avoid scalding. Currently i only have a t p relief discharge line that runs down to just above the pedestal and out through the exterior wall. A trapped tpr dischage pipe is a common defect when a replacement water heater s tpr valve is lower than the original one and the installer connects to the exisitng discharge piping at the wall. Ultimately should the water heater t p discharge pipe be run to the exterior of the crawl space.

Water heaters should have a temperature and pressure relief valve for safety purposes. When the temperature gets too high the valve opens up and water runs out through it. I would like to install a drain pan under the water heater. A watts 210 valve can be installed.

The tpr valve will activate if either water temperature measured in degrees fahrenheit or pressure measured in pounds per square inch psi exceed safe levels.
