Shower drains last a long time, but eventually they will need to be replaced. A plumbing professional can take care of the problem for you , or you can try to replace it yourself. You can complete this job yourself with a few materials from your local home improvement store. Replacing your shower drain is rather easy. You will need access to your basements, or crawl spaces in order to complete the work. Follow these steps to replace a shower drain.

Step 1 - Remove Old Drain

The old drain is sometimes challenging to remove. Use the hacksaw blade to cut as much of the drain out as possible. If there are parts that you can’t remove with the blade, use a screwdriver to force them off. Pull the drain completely out and remove the washer as well. You will have to stick your hand in the drain to get the washer out.

Step 2 - Put Components in Place

Place the nut and rubber washer in place. They need to be placed in the sink, down into the shower drain, below the tub line. Next you will add a soft flexible washer or plumber’s putty. Set the top of the drain into place and screw all of the components together. It is especially important that you don’t over tighten as you screw the parts together, because if you do, the threads will not work properly.

Step 3 - Test Fit the Drain

Test the drain to ensure it fits before you seal it into place. Connect the swivel connector to the p-trap of the pipes. Attach the female side of the trap to the drain pipe. Next, connect the swivel nut to the elbow pipe that measures a 90° angle. Once you’ve determined that all of the pieces fit together properly, separate them and set them aside to be sealed. If the new drain seems too short, you can add onto the drain pipe or shorten the base of the swivel connector.

Step 4 - Glue the Drain

Glue all of the pieces together using an all purpose cement. Glue the swivel connector to the p-trap. Next, glue the 90° elbow to the drain pipe. You have to make sure that it is in the proper position. Mark it with a grease pencil during the test fit. Then be sure to glue them together in the same way that you fit them together for the test fit. You want a good seal on these pieces, so apply glue generously. Screw the remaining pieces together and check for leaks. Replacing your old shower drain doesn’t have to be the job of a professional.
