Installing Kitchen Sink Drain Plumbing

Installing a drain should not take very long.

When you install the drains plumbing for your sink you need to purchase two different PVC plastic kits. The first kit comes with the pipes and fittings needed to connect both sink basins. This includes the fittings for the basket drains and the T-fitting to connect everything together. The second kit is the trap. The trap is the S-shaped pipe that prevents sewer gas from coming up through the drain.

Things You'll Need

• Thread putty
• Pipe wrench
• Basin kit
• Trap kit

Instructions

1. Coat the threads on the bottom of the sink baskets with thread putty.

2. Slide the metal nut that came with the sink basket over the straight pipe with the flared end on it. Place the white slip-joint gasket onto the flared end of the pipe and thread the nut onto the bottom of the sink basket. Do this with both basins. Turn the nut tight with a pipe wrench.

3. Secure the long pipe with the elbow on it to the pipe secured to the left basin. Position the pipe so the long end faces the basin on the right. This pipe routes the water from the left drain over to the main sink drain. Hand tighten the fittings at this time.

4. Secure the T-junction pipe on the right basin and connect the cross pipe from the left basin to the T-junction pipe. Again, hand tighten the fittings.

5. Secure the S-trap onto the T-junction and the metal drain pipe extending up through the floor. If you have a newer home and the sewer pipe goes straight back into the wall, install a P-trap.

6. Tighten all of the large white nuts that connect each piece of PVC by turning each nut a quarter turn with a pipe wrench. Do not over-tighten the nuts or you will strip the threads.
