Tankless Water Heater T And P Valve

My personal opinion of tankless heaters is that they are way too expensive to install and maintain never mind that few plumbers know how to service them.

Tankless water heater t and p valve.

So consult the manufacturer s installation manual. I d check the pressure on the house before you go to the extent of changing the t p valve. This valve may sit quietly unnoticed on your water heater but it has a very important purpose. To keep your heater from exploding.

This is just a pressure relief valve i used with a tankless water heater. This is one of those things that should never be needed unless something goes very very wrong with the tankless water heater. Gas fired tankless water heaters will usually require a pressure relief valve while electric on demand water heaters may not. The takagi gas fired tankless water heater manual specifies a pressure relief valve on the hot water outlet.

I m betting the pressure is a little high and the act of water hammer is pushing the valve open a little. On the side or top of your water heater tank is a valve connected to a metal or plastic discharge tube pointing downward. The valve is called a t p valve or tpr valve for temperature and pressure relief. In my application code requires a pressure relief but not a temperature relief t p.

They are prone to failure particularly if there is any water condition hard water etc at all. The t p relief valve short for temperature pressure relief valve is a critical safety device on your water heater. Tankless heaters are required to have a pressure relief valve.
