Installation Notes
Shut off the pump and relieve system pressure. Cut the line square and clean/prime the pipe and valve sockets.

Allow proper cure time before pressurizing, then check for leaks and verify smooth system operation.
Maintenance Tip
Inspect annually for signs of wear or debris that may prevent full closure. If backflow or chatter is observed at pump shut-down, service or replace the valve to protect equipment and maintain hydraulic efficiency.
