CALEFFI AUTOMATIC FILL VALVE AND BACK FLOW PREVENTER COMBO. INSTALLATION

[@tonymanero5544]

As Alex mentioned, the Caleffi PRV has a set screw to adjust water pressure from 0 to max, but he didn’t mention there’s also a dial with psi marking. So at 15, the dial shows 15 or if you want to have it 13, turn to set screw to the 12 marking on the dial. This Caleffi model also has the psi gauge after the pressure reduction stage to show psi within the system, to confirm system pressure matching the set screw selection.

Hi Alex: What is the function of the knob at the bottom of the automatic fill valve? What should it be set at during normal operation? Thsnks

[@tonymanero5544]

The knob opens or closes water through the fill valve.

My favourite brand caleffi. It needs pressure reducing valve before tho to protect the auto filling valve

[@alexthehandyman3494]

Hello John. Thanks for your comment That valve is a pressure reducer valve and automatic fill valve combo at the same time . It reduces the pressure from 40-50 from the municipal feed to 15 lbs design by factory ( adjustable pressure) It doesn’t make sense to install a pressure reducer valve before another one It would be redundant. If the house or building have high pressure from the municipal fed,.then at pressure reducer valve is installed bright after the meter before it distributes the water . Please let me know if Ian missing something.

Wrong. You didn't ream the inner or outer of the pipe . That is a must when doing pro press , Every plumber should know this.
