How to Install a Bath Tub Plumbing Trap

    • 1). Hold the pop-up drain in one hand with the nut facing down. Unscrew the nut, using the pipe wrench if needed, with the other hand. Remove the rubber washer.

    • 2). Apply an even line of plumber's caulk around the underside on the rim at the top area of the pop-up drain. The rim is the portion that will sit on your tub floor.

    • 3). Place the drain into the drain hole of your bath tub. The plumber's caulk and rim should be sitting on the edge of the drain hole.

    • 4). Replace the rubber washer from underneath the tub. Screw the nut into position by hand. Do not yet tighten completely with the pipe wrench. Wipe away any excess plumber's caulk.

    • 5). Apply a layer of pipe cement to the lip of the under-curve section of the p-trap and to the bottom of the swivel connector piece. The bottom of this piece is the non-moving end.

    • 6). Slide the bottom of the swivel connection into the end of the under-curve p-trap section. Turn clockwise a quarter turn, by hand, and the hold in place for about 60 seconds.

    • 7). Apply a layer of pipe cement to the other end of the under-curve p-trap section and the male end of the elbow section. The male end has threading on the outside of the pipe.

    • 8). Place the thread end of the swivel connector onto the bottom of the pop-up drain and screw the larger nut piece upward, by hand. You should stop when the rubber washer of the pop-up drain is inside the pipe.

    • 9). Attach the under-curve and elbow sections of the plumbing trap together by screwing the large plastic nut up the threading of the male end of the elbow and tighten completely using the pipe wrench. Tighten the nut joining the plumbing trap to the pop-up drain completely using the pipe wrench.
