My water line pressure is about 65 psi, but I need to bring it down to 55-60 psi, so as not to stress the pex tubing in my radiant floors. I installed a Cash Acme EB86U (3/4") pressure regulator, but noticed two problems: the downstream pressure will creep back up to the inlet pressure after a while, and the flow rate has been seriously impacted.
From the specs that I've seen all pressure reducing valves, the smaller the pressure difference across the regulator, the worse the flow rate. Increasing the inlet size seems to make a difference. Maybe going to a 1" model will help? Is there any advantage to using a cartridge style, like a Watts X65B?
Can anyone recommend a regulator that has a good flow rate for small pressure drops, and also won't creep?
cheers, Grant.
