  5. Install waterproofing membrane per manufacturer’s recommendations. Seal membrane to PVC CPE flange body underneath.
  6. Install top section of CPE flange outlet adapter.
  7. Test membrane for leaks.
  8. Position threaded/rubber push-fit coupling in PVC CPE membrane body at correct position/height.
  9. Solvent weld shower channel pipe to threaded coupling/push channel spigot into rubber coupling (using dish detergent to assist fit), at correct floor orientation.
  10. Cut plastic installation feet to height to rest on membrane and keep shower channel stable.
  11. Trowel mortar to required height, allow for thickness of tile and thinset mortar, grade to create minimum 2% slope towards drain.
