This post is a followup to an earlier post that I made re the installation of a water pressure reducing valve. I've got a Watts Series 25AUB valve that I am planning on installing along with a expansion tank that was recommended by Deb; I got off my butt and searched the forum postings for more info about the expansion tank and decided I would go ahead and install it with the prv.
However, I still need some advice about the installation of the PRV. I'm going to be installing the PRV after it enters the house, but have run into a problem with the water line and the floor joists. The line runs perpendicular to the joists (the pipe, not surprisingly, is hung from the joists) and the clearance from the bottom of the joists to the top of the floor boards is not enough to accomodate the prv. The plumbing supply store recommended getting a couple of elbows and simply adding a "U" shaped" drop in the line to accomodate the prv - the prv would sit at the bottom of the "U." My question is whether or not I couldn't simply have the valve sit on the main lane as it is and have it oriented so that the adjustable screw points downwards; the prv would in effect be hanging upside down. Would this impact the functioning of the valve? The install instructions don't seem to address this issue.
If such an approach would impact the functioning of the valve, what do you folks suggest as far as the safest and most stable way to integrate the prv into the existing line given the existing construction. I searched through older posts and couldn't find anyone else asking this sort of question, so I am hoping that someone can answer this question. Thanks in advance.
