How to Put in a Bathroom Sink Drain

Installing a bathroom sink drain is an essential plumbing task that requires attention to detail and precision. It is crucial to understand the various aspects of this process to ensure a successful and leak-free installation.

Tools and Materials:

Wrenches (adjustable and basin)
Pliers
Putty knife
Plumber's putty or silicone sealant
Sink drain assembly
Strainer basket

Step 1: Remove Old Drain Assembly

Using an adjustable wrench, loosen the slip nut that secures the old drain assembly to the sink. Disconnect the drainpipe from the tailpiece using pliers. Remove the old assembly and clean the drain hole thoroughly.

Step 2: Apply Putty or Sealant

Roll a rope of plumber's putty or apply a bead of silicone sealant around the rim of the new drain assembly. This will create a watertight seal between the drain and the sink.

Step 3: Install Drain Assembly

Insert the new drain assembly into the drain hole, aligning it with the putty or sealant. Tighten the slip nut using an adjustable wrench until it is snug but not overtightened.

Step 4: Connect Drainpipe

Reattach the drainpipe to the tailpiece of the drain assembly. Tighten the slip nuts using a basin wrench to create a secure connection.

Step 5: Install Strainer Basket

Place the strainer basket into the drain assembly. It should fit snugly and prevent debris from entering the drain.

Step 6: Test for Leaks

Fill the sink with water and check for any leaks around the drain assembly. If any leaks are detected, tighten the slip nuts until the leaks stop.

Conclusion

Installing a bathroom sink drain requires a systematic approach and attention to detail. By following these steps and ensuring proper connections and sealing, you can effectively replace or install a sink drain, ensuring a functional and leak-free bathroom sink.
