Wilkins 115-975XL2 1.5-Inch Lead Free Reduced Pressure Backflow Preventer

Reduced pressure principle backﬂow preventer consisting of a pressure differential relief valve located between twoindependently operated spring-loaded center guided check valves, “Y” pattern body.
Complete with two full port resilient seated ball valves for shut-off and four resilient seated ball valve test cocks.
Pre-plumbed backﬂow station. Assembly can be of the reduced pressure principle or of the double check type.
