Pop-Off Valve Replacement
Any one replaced their pop-off valve on their water heater? Hoping there is a link somewhere. If not any "tips" from those owners who have replaced theirs? Thanks in advance! Mike

Easy to replace is relative........
Old rusty will be hard to unscrew
Access can be very tight due to location and exhaust venting in the way
Camco makes a wrench for them
The T&P valves are just like ones in home water heaters. Just need to get the correct size (Thread) Sensor probe sits in water.
210*F/150# (Full pop open values)
Weeping can be due to build up on valve disc/seat.....open/snap close couple times with water on and cold. Stand back it will spray :B
Weeping can also be due to loss of air pocket (designed into tank)
As water heats it expands....air controls the increase in pressure due to expansion (air can be compress/water can't)
So if air pocket is gone...water heats/expands....pressure increases...T&P will weep.
Re-establish air pocket------weeping should stop
Turn water off..open faucet...open T&P until water stops flowing...let T&P snap close.....turn on water/close faucet
Simple thermal dynamics
