Drain Installation
Be sure to check all local plumbing codes before beginning any plumbing
installation.
Disassemble drain completely. Unscrew and remove outer locknut, friction
and sealing washers, remove strainer and internal wrench, unscrew
compression nut and remove compression gasket from drain.
Before the shower base is set in the floor, attach the drain to the shower
base. Apply a thick bead of 100% silicone sealant around the underside of
the drain top flange. Install the drain body through the hole in the top-side of
the shower base. Push and hold drain body against the shower module floor.
From the bottom side of the shower base, place the black rubber sealing
washer, then friction washer, up over the threaded drain body. Be sure there
are no obstructions and that the sealing washer makes clean, even contact
with the bottom of the shower base. Holding the drain body in place, engage
the outer locknut and tighten up against the two washers.
NOTE: The poly friction washer is intended to protect the rubber washer
from damage while the bottom portion is threaded on and tightened up.
Wipe away excess silicone that has squeezed out from the top-side of the
shower base.
Measure and cut the drain pipe stub-up, such that when the shower base
and drain assembly is in place, the top of the pipe is between ½" and ¾"
below the top of the drain body. Set the base and drain assembly in place
according to the base manufacturer's instructions. Position and lower the
assembly over the drain pipe so that the pipe comes up through the drain
body.
Once the base is lowered, adjust the pipe or base so that the pipe is
centered within the drain body. Confirm the top of the pipe is between ½"
and ¾" below the top of the drain body.
From the top side of the shower base, push the compression gasket over
the pipe with the taper side up. Slide the gasket down over the pipe into the
drain body until the bottom of the gasket sets against the bottom of the
drain body. The top of the gasket should be flush with the top of the drain
pipe, or slightly lower.
Place the compression nut over the pipe and, using the internal wrench,
thread the compression nut into the drain body over the gasket. NOTE: Take
care not to cross thread. Tighten the compression nut completely to form a
tight seal between the gasket and the pipe. Carefully remove the wrench
and keep it for any necessary re-tightening.
Allow 24 hours for silicone to cure. Then check for leaks. Turn water on in
shower and from below shower floor (if accessible), check the drain area for
leaks concentrating on 1) the area between pipe and compression gasket
and 2) between shower base and sealing washer. If a leak occurs in area 1),
use the internal wrench to tighten the compression nut. If a leak occurs in
area 2), tighten the outer locknut.
When installation is complete, remove the adhesive cover from the strainer
and install into drain.
