This wouldn't be a good idea as the PRV is such a critical component of preventing blown I-beams. I think you can actually adjust the Leafield PRV to leak at different pressures anyway by rotating the little flat disk in the bottom using something like a paper clip to make it turn. If in doubt, put some water in it and look for bubbles, if you see them and the floor's softer than you like or whatever the max PSI should be, clean it out or replace it. If its not the PRV, then check the SB floor for leaks with soapy water. There's also a good chance a leak may be coming from around the PRV rather than the PRV leaking itself. Get a valve wrench and crank it down pretty well after cleaning all surfaces involved.
As for the older Hysides, from what I understand, the brand was the SunRunner in the old days (early 80s?). Kjirsten's (TakeMeToTheRiver) got an old one and can talk about their quality - I think she's pretty happy with it.
ADMIN NOTE - this and the other floor pressure post are being merged and stuck into "gear talk" because its all relevant to the same stuff and is about our gear. - AH
