Pressure Release Valve - Replacement

[lebolewis]

Well, it finally gave up......my cold water Pressure Release Valve has been drip, drip, dripping now for some time......but now it is pouring a steady small stream. Got to replace it and it's a bugger to get at.

Airstream in Jackson is closed today (New year) and I was just wondering if anyone has some experience replacing one of these. For instance, can I buy one of these valves locally or from the Internet? The fittings all look to be 1/2 inch regular pipe thread. But.....don' know what the fixed release pressure is?

Any help would be appreciated. Bill

Airstream used a cold water relief valve rated to vent at (IIRC) 60 psig. Hardware store models are rated at 90 psig. InlandRV sells an Airstream-approved cold-water replacement.

I've' got five years of camping on my hardware store replacement.

There has not been a problem associated with my choice of parts.

The water "pop off valve" is Airstreams part # 000111. It's rated at 60 psi. DO NOT go above that psi rating.

However, you cannot purchase that kind of part from them unless your in Jackson Center.

Thanks to everyone for the info.

I'll look around and see what I can find that releases at 60lb, or a bit less.

do they even put these, or anything like this, in new trailers?

Yes,they are still used.

They are a great protection for the plumbing system in the trailer.

Like extra insurance, if you wish.

Where is this located? I know, different locations depending on different models...

This isn't the pressure regulator part that is integrated with the fresh water inlet, is it?

Bill,

Are you sure it's busted?
Do you have a pressure gauge?

[lebolewis]

On my 76 Sovereign this valve is locate in the cold water line, just past the adjustable main pressure regulator. It dumps into a plastic line that goes down through the belly pan and on to the ground. Bill

I got a replacement at a local industrial supply store for about $25, it has 1/2" npt and adjustable pressure settings.

The pop off valve is usually located close to the water pressure regulator.

The correct part, does not have an adjustable setting.

It has been dripping for some time......even when I have the 40psi in-line pressure regulator in my fresh water hose, that you can get at Wal-Mart, installed. Bill

I'm not saying it isn't busted, but without a pressure guage its hard to tell.

It's not impossible that the pressure regulator is leaking, especially the in-line Walmart models.

Still searching locally for a replacement for my failed cold water pressure release valve. I understand that the original valve was designed to release at 60psi. I have found two possibilities.....one a valve that is fixed to release at 50psi......and another that is adjustable to release at 50psi or 75psi and in 25psi increments up to 150psi.

Does anyone know what the main adjustable cold water regulator in an Airstreams is factory set to?

Thanks, Bill

Airstream has the water pressure "regulator" set at 50 psi.

DO NOT use a pop off valve that's 50psi. If you do, it will continuously leak.

That's why Airstream's pop off valve is set to 60 psi.

If you cannot find the correct valve, Airstream has them available thru dealers.
