Installation Guide

Be sure to check all local plumbing codes before beginning any plumbing installation.
Disassemble the drain and separate the top portion (male threaded top and strainer) and the bottom
portion (female threaded body and two washers).
Before the shower base is set in the oor, apply 100% silicone sealant to the underside of the drain
ange and underside of the square strainer frame. Place the top portion through the hole in the top
side of the shower oor.
From the bottom side of the shower oor, place the black rubber sealing washer, then the poly friction
washer over the male threads. Be sure there are no obstructions, and that the sealing washer makes
clean, even contact with the bottom of the shower oor. Holding the top portion in place, engage
the bottom portion of the drain over the male threads and tighten. [Note: The poly friction washer
is intended to protect the rubber washer from damage while the bottom portion is threaded on and
tightened up.]
From the top side of the shower oor, wipe away excess silicone that has squeezed out from under the
top portion. There should be an uninterrupted bead of silicone between the strainer frame and shower
oor. The shower oor is “sandwiched” between the top portion and the bottom portion. The rubber
sealing washer and silicone sealant keeps the drain watertight.
After setting the shower oor in place, solvent weld the drain pipe into the hub of the drain according to
the glue manufacturer’s instructions. Allow 24 hours for the silicone to cure, then check for leaks. Turn
water on in shower, and from below shower oor, check the drain area for leaks concentrating on the
area between pipe and drain hub; and between shower base and sealing washer.
