If you've got a leak in your shower, you might need to patch your PVC pan liner. It can be hard to tell where a leak is coming from, as water can flow in many directions. A properly installed liner, tightened to the clamping drain, should be waterproof. However, some people use silicon around the ring for added protection. If you're looking to patch a small hole, you can use PVC primer and PVC hot glue, which chemically welds PVC together. For larger jobs, you may want to use a product such as KerdiFix, a urethane sealant, or Oatey PVC Shower Pan Liner Adhesive Cement.

What You'll Learn
Using PVC primer and hot glue
To patch a PVC pan liner using PVC primer and hot glue, you can follow these steps:
First, ensure you have the correct materials. You will need a PVC primer, also known as PVC glue or cement, and hot glue or PVC bonding adhesive. Make sure the work area is well-ventilated, as the solvent vapors from the primer and cement can be dangerous to your health.
Next, prepare the surface of the PVC pan liner. Wipe the area that you will be patching with the PVC primer. Allow the primer to dry for about 10 seconds.
Once the primer is dry, apply an even layer of the solvent PVC cement or hot glue to the surface. Ensure that you cover the entire area that needs to be patched, but do not apply too much pressure to avoid excess glue.
Finally, carefully join the patched piece to the PVC pan liner, twisting and pressing gently to spread the solvent cement and ensure a solid joint. Hold the patched piece in place for about 15 seconds to prevent it from coming loose.
This method should create a strong, lasting bond and a watertight seal, making it an effective way to patch a PVC pan liner.

Using waterproof duct tape
Waterproof duct tape is a viable option for patching a PVC pan liner. It is a quick and simple solution that does not require extensive plumbing or construction knowledge. Here is a step-by-step guide on how to patch a PVC pan liner using waterproof duct tape:
Prepare the Area
Before applying the duct tape, ensure that the area is clean and dry. This is crucial to ensure that the tape adheres properly to the surface. Use a clean cloth to wipe down the area, removing any dirt, grime, or leftover residue.
Measure and Cut the Tape
Measure the size of the hole or damaged area in the PVC pan liner. Cut a piece of duct tape that is slightly larger than the measured area. The tape should overlap the damaged area on all sides to ensure a proper seal.
Apply the Tape
Peel the backing off the duct tape and carefully place it over the hole or damaged area. Smooth out any air bubbles or creases to ensure the tape adheres firmly to the surface. Apply pressure as you work your way around the patch to create a tight seal.
Overlap the Tape
For added strength and durability, consider overlapping multiple layers of duct tape. After applying the first piece of tape, slightly overlap the edges with subsequent pieces. This technique will reinforce the patched area and reduce the likelihood of leaks.
Maintenance and Monitoring
While duct tape can provide a temporary solution, it is important to monitor the patched area regularly. Depending on the location and severity of the damage, the duct tape may need to be replaced periodically. Check the tape for any signs of wear and tear, and replace it as necessary to maintain a watertight seal.
