Product Details
This check seat is designed for compatibility with the 4" Watts 909 series Reduced Pressure Zone (RPZ) backflow preventers, fitting both the first and second check assembly. To replace the old seat, simply slide two retainer wires out from under the seat and pull the seat straight up, ensuring to lube the O-ring before installing the new seat. No special tools are required for servicing, and it comprises genuine Watts replacement parts, maintaining the integrity of the backflow preventer system.
