Backflow Prevention



Bronze, Wye-Pattern Combination Clean and Check Strainers



1 in. (25mm)


Series 777C Wye-Pattern Combination Clean and Check Strainers ensure proper operation of reduced pressure backflow preventers. The strainer's 20 mesh screen catches suspended particles prior to them reaching the check valve assemblies thereby reducing unnecessary service calls and expensive emergency repairs. Watts Series 777C strainers lock in the pressure between the strainer/check and the inlet of the reduced pressure backflow preventer, preventing nuisance discharging of the relief valve. Maximum Pressure: 200psi (14 bar).
