For applications on concrete slab subfloor ensure a
minimum 4.5" diameter recess in the center of the
shower floor where the tile shower drain would normally
be positioned. Disassemble the tile shower drain.
Place the shower drain base into the opening so that
the drain base rests level on top of the concrete slab.
Measure and cut vertical drainpipe to desired length.
Ensure pipe ends are cut square, deburr the inside and
chamfer the outside of all pipe ends, and remove all
debris from pipe ends and hub connection of drain body.
Interference fit between pipe and fitting hub must be
completed prior to primer and cement application. Pipe
should easily go 1/3 to 2/3 the way into the fitting hub.
If provided, install Oatey Reusable Tool-Free test plug by inserting and applying a 1/4 turn to seal
in place. Rated to hold up to 40 feet of head pressure.
Note: Otherwise, proceed by covering the drain base opening with duct tape to keep debris from
entering the drain.
Properly backfill the recess around the drain base by following mortar manufacturer’s recommendations.

Next follow steps in solvent welding the drain base to the drainpipe using an approved Oatey
primer and solvent cement.
• Apply primer inside the fitting hub, then the exterior of pipe end and again the fitting hub.
• Once the primer has been applied to both surfaces, the cement must be applied within
5 minutes. If not, you MUST prime the surfaces again before applying cement.
*Do not use primer on ABS pipe and fittings.
• Turn drain base 1/4 of turn as you push the pipe end into the fitting hub.
