Hello,
I have a Watts pressure regulator valve that I need to replace. The existing one developed a hole right in the middle of the strainer retainer cap which I thought was very odd. At any rate, the unit is older so I figure it would be a good idea to just replace it.
Watts told me that their LF25AUB-Z3 would be a direct replacement with no cutting and/or soldering of the existing set-up. But I have a few questions about replacing it. First off, from the pictures I sent them (below), they said it looks like it is a 1” unit. The pipe size is 3/4". So maybe these are adapter fittings at the top and bottom to adapt it to 1” threads? I’m not familiar with what I’m looking at here. I can make an assumption that maybe that is some sort of a union at the bottom. So would the idea be to put a wrench to the right on the big nut at the bottom and pull it towards me? Would that loosen the bottom somehow anc create some clearance? Then put a couple wrenches at the top and unscrew the entire valve assembly? Also, since there is not enough clearance because of the wall, I’m assuming I will have to take out the 4 bolts holding the adjusting stem assembly of the valve and take it out. I’m assuming there is no harm in doing this to the new one?
Thanks for any help and sorry for the basic questions.
