Even though plumbing jobs are not exactly the most exciting aspect of a restoration or repair job, they must be completed. There are several tasks that you should probably delegate to trained professionals. However, the ability to repair or install a drain for a bathroom sink is a skill that any do-it-yourselfer should be able to handle. 

It is a simple and quick process to connect the drain pipe from a bathroom sink to the drain plumbing in your home. The drain and water-supply connections are often placed in this fashion, which is true regardless of the style of sink one purchases.

Things to Consider Before Installing a Bathroom Sink Drain

  • Before you commit to the final installation, you should always run a preliminary test fit, take measurements, and make cuts. 
  • The angle on slip washers and gaskets should always face the connection joint when installed (or where the two ends will meet).

The Process To Install A Bathroom Sink Drain Pipe

Step 1: Form a piece of plumber’s putty roughly the size of a gummy worm by rolling the putty between your hands. Putty should be rolled out and wrapped around the sink flange’s underside. In the sinkhole, insert the flange. Firmly secure with pressure. 

Step 2: If not already completed for you, put the locking nut and flat washer over the pop-threads to put the pop-up body together. The rubber gasket should be added last. The tapered end of the gasket needs to face up. 

Step 3: Using the hole on the underside of the sink, screw the pop-up body to the flange. Ensure that the pivot rod opening is facing the sink’s rear. 

Step 4: Hand tighten the pop-up body’s locking nut until the gasket is snugly affixed to the sink’s underside. Two or three more rotations should be compressed using the channel lock pliers. Avoid over-tightening. If necessary, remove any extra putty from the flange. 

Step 5: Insert the pop-up stopper into the drain opening. Make sure the pivot rod hole is facing the back of the sink.

Step 6: Pass the lift rod through the sink faucet’s top. 

Step 7: Secure the lift rod with the extension strap underneath the sink. 

Step 8: Insert one end of the pivot rod through the stopper’s hole and into the pop-up body. Over the aperture for the pivot rod, tighten the nut. 

Step 9: Insert the other end of the pivot rod through the attachment clasp and extension strap, as depicted above. Connect the pivot rod and the extension straps, test the pop-up, and make any necessary changes. 

Step 10: Screw the tailpiece to the pop-up body after wrapping thread tape across the tailpiece’s threads. (Your drain kit ought to come with thread tape.) 

Step 11: Slide a slip nut, then a reduction washer, over the tailpiece’s end if required. Ensure that the washer’s beveled edge is pointing downward.

Most sinks, whether in the kitchen or bathroom, will operate in this manner. There can be a few minor variations for unique circumstances or designs, but once you comprehend the procedure, it should be simple to identify any necessary adjustments.
