Stuck Water Heater Pressure Relief Valve...

[Newyooper]

I'm trying to replace the pressure relief valve on my RV water heater, but it will not budge. Any thoughts on how to loosen it up???

If it was mine, I would try a small pipe wrench to loosen it. Might try spraying PB Blaster on it. PB Blaster should work it's way down into the valve's threads. Might take a day or two with multiple sprayings. Try this at your own risk.

X2 PB Blaster and let it sit a day or two.

Thanks for the information. Luckily, I work for a plumbing and heating company. I had one of our service techs stop by this morning, and he was able to get it loose. Thanks again!

How did he get it loose ?

RacerX179, he was able to get a pair of channel locks on it.... Having the right tools always helps...
