Installation Notes

Faucet seat replacement is performed by licensed plumbers or qualified service technicians. Shut off the water supply to the fixture at the stop valve before disassembly. A seat wrench sized to the existing seat is required for removal and installation of the replacement seat. Do not overtighten the seat, as this can crack the faucet body or distort the seating surface.
