To install a No-Caulk Shower Drain, start by applying a ½-inch bead of plumber’s putty (or silicone for ABS drains) to the underside of the drain flange and inserting it into the shower base. From below the base, place the rubber sealing washer and friction washer over the drain barrel and tighten the locking ring to secure it. Next, set the shower base into its final position. Place the rubber pipe gasket over the drainpipe and push it into the drain body. The flat side of the gasket should be at the bottom of No-Caulk drain body, seating onto the inside lip of the body. The beveled side of the gasket will be facing up.Tighten the gasket set screw or compression assembly to create a watertight seal, then snap the drain cover into place.
