I have a gas leak in the gas regulator of my 50 gal water heater. I
plan to replace the gas regulator on the water tank as the most cost
effective fix, something I have never done before. I shut off the gas,
disconnected the gas line, and burner, pilot, thermostat assembly. I am
now ready to remove the regulator/thermostat.
I assume I need to shut off the water and drain the tank first. Is this
Does the regulator/thermostat just screw in like a pipe thread ? that
is do I just unscrew the regulator to remove it ?
Thanks for any help.
Yes, yes, and yes.
It's 3/4" pipe thread.
Drain tank to about level of the control.
It may take a big pipe wrench to loosen.
Coat threads of new control with ______________ of your choice.
See lengthy discussion on thread sealing over the past weeks.
You may have trouble getting the flare gas fittings to
seal again. Check carefully for leaks.
Leave T&P valve open as tank refills to exh air.
how olds the tank? if its more than 6 years old your probably better
off just replacing the entire tank, since the gas valves are pricey...
be prepared to replace the tank drain valve, many are plastic or so
cheap if you get them open they will never close again....
open the T&P valve to let air in so the tank can drain, be prepared to
replace that valve too, once disturbed they often dont shut good and
have a piece of pipe to put on the end of the wrench to remove the
thermostat it may be near impossible to get lose.
short and long start first thing in AM on a day part stores are open,
since this job may expand repeatedly:(
If your lucky it might be a snap
