3. Unthread the stop body (#2). Do not touch the center screw (this effects the water flow).

Version 1: Use pliers to unthread by the outer edge of the stop body (#2).

Version 2: Use  pliers or 5/8" deep well socket to unthread by the hex portion of the stop body (#2)

4. Use pliers to pull the check stop (#3). Clean the check stop (#3).

Assembly:

  1. Slide the check stop (#3) into the valve body (#4).
  2. Use pliers to thread the stop body (#2) in very tight. Do not touch the center screw (this effects the water flow).
  3. Slide the escutcheon plate (#1) back on.
