Pressure Relief Valve ??

I am having problems with understanding the Pressure relief valve.

The PO capped one side.

Does the top of the valve blow?

With the water regulator being set at 45# and the pressure relief valve at 60#, I would think that there are other connections that would blow before the 60# relief valve.

Thanks in advance

That valve has probably been capped because it failed, and started leaking.
There is a second failurepoint at the top of the valve as well. Ours failed there this Spring.

Meddle not in the affairs of dragons, for you are crunchy, and taste good with ketchup.

Your Airstream has an interesting collection of plumbing - all the major food groups appear to be covered.

My Overlander's original OPR valve did not leak UNTIL I tested its cracking pressure during the refurb. After that, it was replaced because it wanted to dribble.

I have noticed the new valve dribbles whenever the water heater is running. I do not consider that a problem because a tube connected to the device directs the water to the ground.
