The last part of your bathroom sink remodel project is installing the sink drain. Plumbing a double bathroom sink requires a drain kit with a "T" and two drain elbows. Double sink drain kits are available at home improvement centers. Purchase the PVC drain kit instead of the metal pipe. The PVC requires less work and is more user-friendly for the home handyperson. When using the PVC material, you eliminate the need for plumbers tape. The slip nut connectors have plastic washers that also keep the draining water from leaking.
Instructions
1. Locate the two elbows in your drain kit. The elbows resemble an "L" shape. Slide a slip nut over each end of the elbows with the threads of the slip nuts pointing to the ends of the elbow. Place the short end over the end of the drain on one sink. Thread the slip nut loosely over the sink drain threads to connect the elbow to the drain. Attach the remaining elbow to the opposite in the same manner. Position the elbows so that the open ends face each other.
2. Find the "T" connection in your drain kit. Place the upper end of the "T" connection against the ends of the two elbows, with the longer pipe of the connection pointing down and centered between the elbows. The upper connection has a bulge visible from the outside. The ends of the elbows should come up to that bulge when you insert the elbows. Cut off the ends of the elbows as necessary with a hacksaw if they are too long.
3. Insert the elbows into the upper portion of the "T" connection, and loosely thread the slip nuts over the connection threads.
4. Pull out the straight pipe with the small curve on one end out of your drain kit. This pipe goes into the house drain pipe coming from the wall and connects to the "P" trap. Slide slip nuts over each end of the straight pipe with the threads of the nuts pointing toward the pipe ends. Insert the straight end of the pipe into the wall drain with the curve end pointing down. Do not thread the slip nut onto the wall drain yet.
5. Position the "P" trap over the end of the wall drain pipe. Loosely thread the slip nut onto the "P" trap. Position the open end of the "P" trap against the lower end of the "T" connection. Cut off the end of the "T" connection as necessary so that the end of the connection will fit inside the "P" trap up to the outer bulge.
6. Slide a slip nut over the lower pipe of the "T" connection with the threads pointing to the floor. Insert the lower pipe into the "P" trap, and loosely thread the slip nut over the "P" trap. Check the fit of all the pipes to ensure there is no binding.
7. Thread the slip nut over the house drain pipe from the PVC wall drain pipe. Tighten all slip nut connections until they are hand tight. Turn each slip nut another half turn with a pair of slip joint pliers. Turn on the faucet and check the plumbing for leaks. Tighten connections further as necessary.
