Description

Designed for installation on potable water lines to reduce high inlet pressure to a lower outlet pressure. The integral strainer makes this device most suitable for residential and commercial water systems that require frequent cleaning of sediment and debris. The direct acting integral by-pass design prevents buildup of excessive system pressure caused by thermal expansion. The balance piston design enables the regulator to react in a smooth and responsive manner to changes in system flow demand, while at the same time, providing protection from inlet pressure changes.

Fantastic product and well made! Great for sprinkler system!

Exactly the same as the one it replaced so it was easy to ID and order. Had my plumber install it but I saved plenty on part mark up

Zurn quality

We were replacing a 2016 identical model Zurn PRV. We are not sure whether 9 yrs was a normal life of a PRV (we think so) or whether we somehow damaged the diaphragm adjusting it this summer. Old one was seeping around the adjustment bolt and Zurn said that meant it was defective. New one went in super easy. The old union was easy to break loose once we bought a larger adjustable wrench and the PEX brass fitting spun within the PEX allowing easy removal. A new rubber union seal and Teflon tape, and the new one works great.

As Good As It Gets!

I very happy with the experience with Supply House. They did their job well. The only negative is the part is made in China (as it seems most things are now).

Perfect replacement

I purchased this to replace a unit that failed after about 10 years in a town home in Warminster. Perfect fit as it was a direct replacement.
