Method 1of 4: Rubber Or Silicone Repair Tape

Rubber or silicone repair tape is the way to go if you’re dealing with a little leak. It comes in a roll like regular tape and is super easy to apply. 

It’s a thick, heavy-duty tape that adheres to itself rather than the pipe. It’s flexible and gummy. So it may be stretched and attached to itself to increase the tape wraps’ compression.

Before you use the tape, lightly sand the leaked PVC surface to make it smooth. Then wrap the tape around the leak. Use the tape to cover a bit of extra space on both sides of the damaged region. 

The tape uses compression to stop the leak. Make sure the wrap is tight and secure before using the pipes again.

Method 2 of 4: Rubber And Hose Clamps

Looking for a temporary repair without needing to go to the store? Obtain a thick piece of rubber as well as a couple of hose clamps.

If the leak in question is in a specific spot, a piece of rubber can fix it. This is a great way to connect PVC pipes without glue.

Fully open the hose clamps to separate them and get them around the pipe. Wrap the rubber around the leaking region and fasten it on both ends with a hose clamp. The rubber should be compressed around the leak while you’re securing it with the hose clamp. 

This should usually stop or significantly slow the leak. Which will give you enough time to develop a permanent fix.

Method 3 of 4: Epoxy Repair

Epoxy repair is a putty-like substance that can be used to repair PVC pipe leaks. Before applying the epoxy repair, make sure the damaged area is clean and dry. Also, ensure that water can’t get to it. This is quite important, or the epoxy won’t cure properly.

After that, apply the epoxy and wait ten minutes for it to cure. After the pipe has been cured, run water through it to check for leaks. You may also follow the manufacturer’s instructions for mixing the putty for more clarifications. 

Make sure to only use good quality epoxy, or it won’t hold up for long. Here are some epoxy repair options you can try:

Fiberglass resin tape is a great way to solve minor leaks in your PVC pipe. This is a very durable material that works for different types of PVC pipes. It employs a water-activated glue that hardens around the pipe and inhibits leakage. The fiberglass tape makes the repair straightforward. 

Clean the damaged section of the PVC pipe with a moist rag before putting the tape. While the resin is still wet, wrap the tape around the leaking spot. After that, let the resin set for 15 minutes.

Follow the manufacturer’s application instructions for the best results. Try to wrap the tape around the leaking location at least 2 inches on each side.

That’s it! By following the above-mentioned methods you can repair PVC pipe leaks easily. If you have a leaking pipe just pick one of the methods and fix it in a few minutes.


Question: Can you use PVC cement to stop a leak?

Answer: No, you cannot use PVC cement to stop a leak. It is made to work hand in hand for PVC pipes. It is not made to be used as a sealer. So it won’t be effective against a pipe leak. 

Question: How long does PVC piping last?

Answer: PVC pipes are extremely resistant to freezing. And, after 25 years, meet almost all new pipe criteria. At 47 years old, the average lifespan is dwindling. Depending on the application and environment, there may be leaks or cracks.

Question: Will a small leak seal itself?

Answer: No it won’t. Leaks that go unaddressed tend to get bigger, so they won’t be tiny for long. And you don’t want water gushing into your home. So it is better to seal it instead.


Now you know all about how to repair PVC pipe leak at joint. If you have any leaking pipes at your home, don’t panic anymore. Simply follow any of the strategies listed above.
