Long time lurker, first time poster here...
I'm looking at add a PRV to an existing underground sprinkler system that was plumbed using 1" PVC. For ease of maintenance, I'd like to mount the PRV above ground on the riser that holds the PVB. Seems pretty standard fare except...I'm not sure how best to connect the PRV to PVC using the minimum necessary fittings.
PRVs come in a variety of connections but the majority seem to have either a single sweat union or dual sweat unions. PRVs with other connection options don't seem to be as readily-available.
So let's say I choose one of the common models that features at least one union. What's the best way to connect that union to PVC? I can sweat the union's brass flange to a short piece of copper to mate to the PRV and a sweat a copper MIP fitting to the other end to mate with a PVC FIP fitting (so the progression would look like PRV-->brass union --> copper stub --> copper MIP --> PVC FIP --> rest of PVC riser) but is there a better way? Does there exist a PVC equivalent to the brass sweat flange so that I can mate a PVC pipe directly to the union on the PRV?
Thanks!
