In 2023, it is still common for homeowners to encounter leaky PVC pipes under the sink. This is due to the fact that PVC pipes are prone to wear and tear over time, and are very susceptible to moisture and temperature changes. When a PVC pipe begins to leak, it is important to address the issue immediately and take the necessary steps to repair the pipe. This article will provide a step-by-step guide on how to fix a leaky PVC pipe under the sink in 2023.

Step 1: Identify the Leak

The first step in fixing a leaky PVC pipe under the sink is to identify the source of the leak. Before attempting to repair the pipe, it is important to determine if the leak is caused by a crack, split, or other form of damage. To do this, inspect the pipe for any visible signs of damage. If the pipe appears to be cracked or split, the leak can be repaired using the appropriate materials. If the pipe does not appear to be damaged, the leak may be caused by a loose joint or other similar issue.

Step 2: Prepare the Area

Once the source of the leak has been identified, the area must be prepared for the repair. Begin by shutting off the water supply to the area and draining the pipes. This will help to reduce the amount of water that can flow through the pipes while the repair is being done. Once the area is prepared, the next step is to gather the necessary supplies for the repair.

Step 3: Gather the Repair Materials

In order to repair the leaky PVC pipe under the sink, you will need the following materials: PVC pipe, PVC glue, PVC primer, a wrench, and a utility knife. All of these materials can be found at most hardware stores. Once you have gathered the necessary repair materials, you are ready to begin the repair.

Step 4: Remove the Damaged Pipe

Using the wrench, disconnect the damaged pipe from the system. Carefully remove the damaged pipe and set it aside. Once the damaged pipe is removed, use the utility knife to clean the area of any remaining residue or dirt. This will ensure that the area is clean and ready for the repair.

Step 5: Apply the PVC Primer and Glue

Once the area is clean, apply a thin layer of PVC primer to the area where the new pipe will be inserted. Once the primer has been applied, use the PVC glue to seal the new pipe into place. Make sure to apply a generous amount of glue to ensure that the pipe is properly sealed.

Step 6: Insert the New Pipe

Once the glue has been applied, insert the new pipe into the area and tighten the connections with the wrench. Make sure to tighten the connections firmly, as this will help to prevent future leaks. Once the connections have been tightened, the new pipe is secure and ready to use.

Step 7: Allow Time to Cure

Once the new pipe has been inserted, it is important to allow the glue to cure completely. This can take up to 24 hours, so be sure to allow plenty of time for the glue to cure before turning on the water supply. Once the glue has cured, the pipe should be secure and the leak should be fixed.

Step 8: Test the Repairs

Once the glue has cured and the new pipe is secure, the next step is to test the repairs. To do this, turn on the water supply and check for any leaks. If the repair has been successful, the pipe should remain sealed and the leak should be gone.

Step 9: Clean Up the Area

Once the repairs have been tested and the leak is gone, the final step is to clean up the area. This includes removing any excess glue and debris, and wiping down the area with a damp cloth. This will help to ensure that the area is clean and free of debris.


Fixing a leaky PVC pipe under the sink in 2023 is not as difficult as it may seem. By following the steps outlined above, you can easily repair the leak and save yourself the time and expense of calling a plumber. Just remember to always turn off the water supply before attempting any repairs, and to use the proper supplies and materials to ensure a successful repair.
