How to Fix PVC Pipe Leak | How to Do PVC Pipe Repair

Leaky PVC pipes can be a drag for anyone. A busted PVC pipe can trigger water leaks and malfunctioning risks. How to repair PVC pipe without cutting it is one of the most common questions asked by plumbers and DIYers. PVC pipes are typically joined using PVC solvent glue. The connection is fast and permanent as it chemically fuses the parts together. The drawback is if you spot a leak in a PVC joint or pipe, it’s impossible to separate the joints to replace the leaky parts. A general permanent repair technique includes cutting back the pipe and installing new couplings and replacement parts.

However, there is a piece of good news; if there is a leak in your PVC pipe, often it can be repaired temporarily until the pipe is permanently fixed or joined. PVC pipes are generally used in low-pressure applications, making temporary repair work easy and effective.

I want to add that the methods mentioned in the piece will also be useful for ABS and PEX pipes. However, the same methods aren’t applicable on CPVC pipes as they are heavily used in high-pressure applications.

Best PVC Pipe Leak Repair Methods –

By Using Rubber and Silicone Tape:

Rubber and silicone tape is thick heavy-duty, stretchy, gummy, and can stick to itself. These tapes work best on cracks in the pipe but not in the joints. Keep that fact in mind to avoid making any mistakes.

To begin with, clean the pipe and fitting with a cotton rag or cloth to make it thoroughly cleaned and dried. Repair tape does work well but will work great if it forms a tight bond with PVC plastic, and that will happen when the plastic is perfectly cleaned before commencing it with the operation.

Cut a piece of repair tape and fold it around the damaged part of the pipe or joint. Keep the wrapping tight and make multiple layers, extending the wraps on both sides, covering portions beyond the leaky part. One major benefit of using a repair tape is that it can be folded around circularly for a significant distance when a medium to big crack appears in the pipe. However, applying the tape at tight spaces can be difficult; in that case, you might have to cut a length of tape and thread it around the pipe.
To check the quality of your work, you will need to test the repair by running water through the drain and watching the repair area for leaking. Repair tape is a temporary solution; you should replace the damaged part of the pipe or fitting ASAP.

PVC Pipe Repairing Using Fiberglass Wrap:

Fibreglass wrap or tape is a fibreglass cloth coated with water-activated resin. It’s a good temporary fix for leaking PVC pipe. The water-activated resin in the fibreglass, when applied, hardens around the pipe and slows the leaking.

Again cleaning and drying the pipe thoroughly of residue and moisture will be the first step. The patch fabric will bond best with the pipe which is dry and free of impurities.
Cut a piece of fibreglass tape or wrap to apply around the leaky area. Wet the fibreglass tape and wrap it tightly around the damaged area. Keep the tape extended at least two inches on both sides for best results. Following the manufacturer instructions will be advisable.
Give some time to the activated resin in the fibreglass to harden fully – It should not take more than 15 -20 minutes.

PVC Pipe Repair Using Epoxy:

Repair Epoxy is used to bond with both PVC pipe and joints, and it comes in both putty and liquid forms.

Utilize a clean cotton cloth to clean and dry the pipe well. The epoxy will bond with the pipe and fittings only when dry and clean.
Now you have to mix the epoxy by following the manufacturer’s instructions. Generally, all such products are two-part formulas where you need to mix a catalyst into an epoxy resin to create the mixture to be used as a patch material.

These products also have some syringe form which eliminates the mixing part for the users as they’re are self-mixing. Just press the plungers connected side-by-side. The liquid epoxy material created by the syringe can be spread over the area directly by the syringe applicator on the damaged area. Other epoxy products require hand mixing to make a putty-like material which needs to be manually applied to the damaged area of the pipe using a disposable putty knife.
Liquid epoxy is better than putty if you’re working with tight spaces. Once mixed, you will have little time to apply the epoxy to the damaged area as soon as the mixture is created.
Apply the mixture properly to the leaking area of the pipe. It is recommended to run a bead of epoxy around the entire joint.

Give the epoxy some time for hardening. So with manufacturers instructions for the required time. Generally, it takes around 20-30 minutes, but sometimes the bond might take up to a full hour to reach its full strength. Once the epoxy is hardened, run water through the drain to check for leaking.

Fix PVC Pipe Leak Using Rubber and Hose Clamps:

Rubber tapes and hose clamps utilize compression to repair small leaks in PVC pipes. It’s a great temporary solution for leak pipes without you having to visit the supply store. If the leak is restricted to one area, you stick a piece of rubber around it. Find a patching rubber (old bicycle tube works well, by the way)

This method is more suitable with the smooth sections of the pipe as they can make full contact with the pipe surface. It doesn’t work very well with the edges where pipes and fittings meet to join.

Clean the pipe properly using a cotton cloth and dry it, especially in the repair area.
Cut a piece of rubber using a utility knife or scissors to be applied around the leak in the pipe. Station the over the cracked area of the pipe.
Station a pair of worm gear hose clamps over the pipe and rubber patch. The clamps should be positioned directly over the ends of the crack in the pipe. Tightly hold the hose clamps until you see the rubber being fully compressed. Stationed perfectly, the clamps should close the crack completely.

As usual, run water through the drain and watch for leaks. The repair method is trustworthy, but only for a given time, meaning it’s a temporary fix. The rubber tape and hose clamps will become ineffectual as the leak grows.

Replacing PVC Pipe and Fittings –

Sometimes, A PVC pipe is so damaged that a simple repair is not viable. In that case, all you can do is replace the damaged part with a PVC pipe. First, turn off the water to the pipe using a local water shutoff switch found near the pipe or turn off the water at the main water supply.

Cut the pipe about 1-inch from both right and left sides to the damaged area using a hacksaw or ratchet cutter.
Drain any excess water from the pipe and clean it dry using a cotton cloth.
Once the affected PVC pipe is separated, dry-fit the replacement pipe in the hole, make sure the new pipe fittings fit correctly with the existing PVC.

Apply PVC primer solvent to the inside section of the replacement’s pipe fitting and to the outside section of the existing pipe.
Then apply glue to the inside of the replacement fitting and to the existing PVC pipe.
Push the pipe into the replacement fittings, using a twisting motion to make sure the pipe bonds with the glue.

Hold the pipe tightly for 10-15 seconds to ensure a strong bond.

Common Reasons for PVC Leaks –

Below are the most common reasons for most PVC repairing and replacements:

Improper Installation: PVC pipe not properly installed onto a joining pipe or fitting is a major reason for leaks. Loose fitting typically allows water to drip.

Incorrect adhesive glue: Make sure you purchase the correct quality PVC cement so it doesn’t wane ahead of time. Before buying glue, read the instructions properly to confirm that the glue is made to adhere to PVC. Most people think glues are the same for all pipes, and that misconception leads to poor pipe glueing and that leads to unwanted leaks.

Cold Temperatures: Although PVC can withstand freezing, it can still become brittle and damaged under extreme freezing temperatures. If you live somewhere with extremely cold temperatures, then insulate your pipings for prevention.
