Installation – Point Drain with Fabric Membrane
- When altering floor joists, consult Structural Engineer for advice and reinforce floor joists as needed.
- Frame out shower surround as required.
- Connect base of PVC CPE membrane body to pipe work, leave drain bolts in place. Block drain opening with rag to prevent floor mortar from entering.
- Connect drain flashing to the PVC CPE membrane body. Seal drain flashing to base, not clamping flange.
- Trowel mortar to required height, allow for thickness of tile and thinset mortar, grade to create minimum 2% slope towards drain.
- Install waterproof membrane per manufacturer’s recommendations. Seal membrane to drain flashing.
- Test membrane for leaks.
- Position threaded/rubber push-fit coupling in drain flange at correct position/height.
- Solvent weld point drain spigot to threaded coupling/push point drain spigot into rubber coupling (use dish detergent to assist), at correct height and orientation.
- Fill mortar inside drain flashing around drain. Protect weep holes on PVC CPE membrane body from obstruction.
- Apply thinset and install tile and grout.
