The tub drain assembly is an important device that prevents bath tub water from draining. It is placed at the back of the bathtub wall and may not appear visibly. The tub drain linkage assembly and the drain stopper both functions to maintain the bathtub water inside. Follow the instructions below to install a tub drain assembly by yourself.

Step 1 - Connect the Drain and the Pipe

The shoe of the drain and the connecting pipe are two main parts which links the drain to its hole. To connect the drain and the connecting pipe, apply a good amount of thread sealant (adhesive or liquid) to the connecting pipe’s line and secure the shoe on the pipe with a screw. Use the pipe wrenches (smooth jawed pipe wrench) to help you secure the shoe in its place with a quarter turn.

Leave the shoe on the drain hole, and place the T-shape pipe on top of the trap adapter so you can get close measurement results. Mark the area where the T-shape and the connecting pipe meets and slice the pipe with the aide of a pipe or tubing cutter specified in the tools list item.

Step 2 - Connect the PO Plug

Detach the pop-up (PO) overflow plug away from the shoe and install the plumber’s putty unto it. Place the PO plug washer above the shoe in such a way that the uneven side is in an upward position. Cap the PO plug atop the drain hole and secure it in place with the aide of a PO plug wrench and smooth jawed pipe in one quarter rotation.

Look for the edge of the connecting pipe (or groove ends which is the T-shape connection) and slip in the lock nut and the trap washer inside the pipe. Before cutting the tubes according to its appropriate dimension, do check if the parts such as the tailpiece, overflow and waste tube are placed on the rim within the T-shape. This is to ensure approximate dimension of the pipe as well as setting an anti-leakage connection. Secure the T-shape with screws leaving the longer side upwards for better access to the overflow tube or receiver.

Step 3 - Connect the Tail Piece

Cut the tail piece using the tubing cutter with the measurements based from the distance of the trap adapter to the T-shape pipe. Remove the cut tail pipe and attach the lock nut and washer underneath it. Like before screw this to keep it intact. Protect the rough edges of the tail piece with an escutcheon. Attach this to the T-shape afterward.

Use ample amount of thread sealant for the overflow tube, and secure the receiver against the tube with screws. Tighten and attach the 2 parts (overflow tube and receiver) using the pipe wrenches (smooth jawed pipe wrench and strap wrench). Cut the pipe with its measurement starting the middle part of the receiver towards the extremely far part of the tube. Finish off the overflow tube installation by replacing the washer and cover for the front hole and the receiver behind the hole. Tighten and screw the parts well.

Cut the remaining pipe with a hacksaw. Check and recheck the tightness of the screw to avoid any further damage.
