This little thing is saving my pipes and fixtures from wear and tear from our high water pressure from city pipes. Our main water line can spike up to 140psi at any given time even with a new ZW main water pressure reducing valve, so I jimmied my pipes with this little thing and the pressure has not gone above 85psi. This thing typically starts discharging smalls amount of water when pressure touches 75psi, and really pours it on around 80psi. But it also does spike to a high of 85psi max when main water line peaks, I’ll take 85psi over 140psi any day.

When I first installed it it leaked. It says it is set at 75lbs but leaked at 55lbs. I took the cap aff and used a screw driver to adjust it to a higher pressure. Works great now!

I used this to replace a 75PSI relief valve that had failed. It fit and operated as per the spec.
