Water supply valves must be shut off. Remove lime and calcium deposits prior to disassembly - see notes below. Use white vinegar or a commercially available product. Apply NSF-61 certified silicone (plumber's) grease to rubber parts and threads, especially retaining cap threads, before reassembly.
- Remove red/blue plug from face of lever handle.
- Use 1/8” hex key to loosen set screw located in hole in face of lever handle.
- Lift lever handle to remove.
- Use spanner to unscrew and remove adjusting ring.
- Unscrew chrome valve retaining cap by turning counter-clockwise. If pliers are required, pad the jaws to avoid damage to chrome finishes. If any significant amount of force is required, STOP - lime or other mineral deposits from your water source have seized the threads. If you continue, the copper supply tube may be bent, broken or pulled from the solder joint - Damage is NOT covered under warranty. Wrap a cloth or paper towel around the base of the retaining cap. Pour white vinegar or a commercial lime remover into the area around the ball valve. Make sure it overflows and runs down the inside of the retaining cap into the threads. This is best done a day or two in advance of the repair. If force is still required use one of these methods: 1) have a helper beneath the sink to hold the valve body in place to prevent it from turning while you unscrew the retaining cap. 2) remove the faucet from the sink and soak the entire valve end of the faucet in white vinegar or a commercial lime remover. 3) cut a vertical slot in the side of the retaining cap from top to near bottom (stop short of cutting into the faucet cover). Cut through the cap but no deeper. Insert a screw driver in the slot and twist to break the threads free.
