Title: Removing the Hot Water Heater Pressure Relief Valve
Post by: Don Malpas on December 21, 2017, 11:27:19 am
I did this years ago. It was easy. Not so now.
There is probably a special wrench designed for the purpose?
If I remove the shroud to the left of the valve I might get a small pipe wrench on it.
Or is there a simple way.
Just want to soak it in vinegar, it's been in there for several years,

Don ... mine was a bit tight when I removed it last year.  I just used a bigger wrench and it broke loose.   If it's really stuck, I might consider a shot of penetrating oil.  And I didn't need to remove the shroud.  The PRVs are rather inexpensive so you might consider a new one.

Is the valve directly screwed into the hot water tank?

Don,

I agree with Ed & Margee.  If you're going to the trouble to remove the valve from the water heater, replacing it is a wise decision IMHO.

Camco sells a tool for removing and replacing the P&T valve:

Camco P&T Valve Removal Tool on Amazon (https://www.amazon.com/gp/product/B003VB15MC/ref=oh_aui_search_detailpage?ie=UTF8&psc=1)

For a one-time use, it's pricey. Better to borrow one from your friend who has every tool- you have afriend like that, yes?

Mark, that is what my service guy used when he did mine a year ago.  It was crudded up and had a slow leak.  He used a 24" breaker bar with a 2 foot pipe extension to break it free.

Ken-

Amazing what a little aluminum/brass interaction can do. I used the tool, but a regular wrench. I suspect it came out easier because the water heater was only a few years old.

I'd offer to give Don the Camco tool I bought (as I shouldn't need it for a while), but it's at home and I'm not.

Not having the dedicated tool, I use a 12' crescent wrench opened up and slipped over the end of the relief, so the wrench is sticking outward. A extra long screwdriver is inserted through the hole in the crescent wrench's handle. It's used with a breaker bar to loosen the valve..

Having trouble seeing this. Is the wrench handle in line with the valve? 90 degrees to the rig?
Picture?
Merry Christmas

does the atwood take the 3/4"(90028) or the 1/2"(91604) valve?

I'm looking at my receipt and it looks like ours was a 3/4" valve, model number is 10473.

Hope this helps.

yep, that's the camco # for 3/4". thanks

fyi all 3 of these part numbers are 150psi valves.

Atwood also has a 75psi, 3/4" RV that is p/n 92647...
