Before you start

  • DO NOT CUT ANY CLOSER THAN 3" FROM THE JET.
  • DO NOT OVERTIGHTEN.

Procedure

  1. Analyze the damaged jet, adjacent fittings, and tube diameters. Choose the parts in the kit needed for the repair job.
  2. Provide suitable protection for acrylic surfaces of the bath.
  3. Remove all attachments to the wall fitting (flange) including ball and retainer assembly or suction hood cover.
  4. Remove the wall fitting (flange) with a jet spanner wrench and ratchet/socket by turning counterclockwise; ensure complete engagement of wrench pins.
  5. Cut all water and air supply tubes to damaged jet housing.
  6. Salvage and clean all removed parts including beveled gasket, wall flange, jet orifice, and orifice insert; inspect for damage. Clean all old RTV silicone sealant from hole.
  7. Using PVC primer and cement, install suitable tube couplings to the cut ends of the air or water supply tubes.
  8. Clean and cement suitable reducing bushings, plugs, or adapters to the new jet or suction housing.
  9. Cut lengths of flexible tubing allowing enough length for complete seating in the jet and coupling sockets.
  10. Slip fit the flexible tubes and temporarily install the housing to the wall flange to check measurements.
  11. Keep the housing aligned with the hole and cement the tubes to the housing and couplings.
  12. Reinstall the wall flange to the housing with the gasket behind the bath wall (beveled edge to the wall).
  13. Draw a bead of silicone around the flange avoiding the threads. Thread flange into housing.
  14. Apply a bead of silicone sealant between the rear bath wall and the beveled side of the gasket.
  15. Complete tightening until the gasket begins to compress.
