Water heater pressure relief valve leaks

[jrbdad]

Our water heater is electric/gas. When we know more then one person will be showering back to back we turn the DSI switch on too for a quicker recovery of the hot water. When we do this the pressure relief valve will drip. this is a new trailer we have been in it about 2 weeks now. Noticed this after a few days.

Bad valve? Can't really take it in for service (living in it).

It's normal, ours does it also when we turn on both electric and gas for quick recovery.

Our trailer is a 2003 and does the same thing since it was new. Its stops dripping after a few minutes. So far no problem letting it drip

Actually, a small leak can be normal. The valve is made to release pressure that is built up when heated water expands. The heater is designed to work with a trapped air space to allow for this expansion, but manually opening the T & P valve releases that air space so it will drip when pressure builds. JMHO, Hank

A Pressure Temperature Relief Valve, dripping while the water heater is

running, DOES NOT mean it is defective. During normal expansion of

water, as it is heated in the closed water system of a recreation vehicle,

the Pressure Temperature Relief Valve will sometimes drip.

The water heater tank is designed with an internal air gap at the

top of the tank to reduce the possibility of dripping. In time, the

expanding water will absorb this air and it must be restored.

TO REPLACE THE AIR GAP FOLLOW THESE STEPS:

1. Turn off main water supply (the pump or water hook up source).

2. Let water cool or let run until cool.

3. Open the hot water faucet closest to the water heater.

4. Pull handle of pressure temperature relief valve straight out and

allow water to flow until it stops.

5. Allow pressure temperature relief valve to snap shut; close faucet;

turn on water supply.

6. Turn on water heater and test
