“Works as intended. Includes (2) 1/2 FIP fittings and (1) 1/2 sweat. Replacing a Watts model, union threads are different. At least this one offers more install options. Only con really is part isn't as readily available. Nor stamped with any branding or PN.”

“This was a replacement for a back-flow preventer with vacuum breaker in the 'auto-fill' water inlet of a Navien combi-boiler. The valve(s) in the old unit had stuck shut so that no water could flow to the auto-fill valve in the boiler. This prevented the boiler from operating due to a low water level. The replacement unit was an exact fit for the old one. I was able to use the old union parts and just slide the new unit into place and re-connect the union joints. The boiler is now operating perfectly again. One lesson learned was to operate the boiler pressure relief valve each year to not only check that it is not stuck (safety issue) but this also lets a little water out of the boiler and in-floor heating coils. The drop in pressure will cause the auto-fill valve to operate and water to flow through the back-flow preventer to bring the pressure up. I believe doing this would have kept the original back-flow preventer from sticking in the closed position. It would have also made it obvious that the auto-fill function was not working. Thanks to Plumbingsupplyandmore.com we have heat again! The service was great and the delivery was quick, considering the time of year and COVID-19.”

“Installed as a backflow preventer for my boiler. Keeps contaminated boiler system water from getting back to the house water supply. Easy to install with both sweat and threaded fittings (I used the sweat fitting).”

“Has fittings for both 1/2 inch sweat and thread so works on either. Couplings that allow valve to be replaced or repaired without disturbing plumbing.”
