Extremely fast shipping.
Played with pressure adjustment. Markings may not line up exactly with actual pressure needed to open the valve but it's close enough. I can finally rest at ease because I was able to easily adjust it to the range I need.

Contains lead. Apparently not allowed for plumbing applications in California.

Other than that, it's adjustable.

Used to replace a 75lb pressure relief valve installed by Ryland Homes, on a county water line, that a county employee told me gets up to 100 PSI. Every other time I ran the Rainbird system, the old valve on the main from the street would open and not shut. If I was away the water ran out into the street. You would think a neighbor might come over and shut it off, it is outside on the house, or ring the bell. I got a $580.00 water bill one month. Tampa, Hillsborough County, FL. Moreover, the old valve would not close again, until you shut the main off and turned it back on.

This one I set at 105 PSI and it has not opened once. I think I might turn it lower, until it does open and see if it closes on its own, once excess pressure is released by it. I have not done that yet.
