How to Patch a Leaky Pipe While You Wait for a Plumber

A leaking pipe can be temporarily stopped with a pipe clamp, epoxy putty, self-fusing silicone tape, or a rubber hose clamp. These are emergency repairs only. All pipe leaks require a permanent fix by a licensed plumber to prevent water damage and further pipe failure.

A leaking pipe can be migraine-inducing for any Ontario homeowner.

Aside from causing water damage to your floors, walls, and furniture, it can also drive up your utility costs. A hole in a water pipe as small as 1.5 mm can waste up to 3,570 litres of water per day and cost you $14.54. That pesky leak adds up fast.

It’s also worth knowing that the fix method depends on your pipe material. PVC, PEX (cross-linked polyethylene), and copper pipes behave differently under pressure, and the pipe diameter affects which repair products will fit properly. We’ll flag which methods work across pipe materials as we go.

If you notice a burst pipe or suspect a serious problem, call a professional plumber and access emergency plumbing services right away. 

While licensed plumbers fix pipe leaks quickly and efficiently, it still takes time for them to arrive, so knowing a thing or two about patching a leaky pipe in the meantime can help you limit the damage until your plumber arrives.

Here are seven DIY ways to do it.

Patching a Leaking Pipe: 7 Temporary Fixes

Assuming things haven’t gotten too bad and you don’t need immediate emergency repairs, these are seven approaches Ontario homeowners can try. 

Disclaimer: DIY pipe repair can help manage a situation temporarily, but always consult a professional plumber before attempting any fix. Mistakes can cause further damage, increase water pressure issues, or void your home insurance. When in doubt, call before you act.

1. Use a Pipe Clamp 

One of the easiest and most effective ways to temporarily fix a leaking pipe is with pipe clamps. They work as their name implies, clamping the pipe to stop the leak. Adjustable pipe clamps are available at any local hardware store and work well on copper, PVC, and most standard pipe diameters.

You’ll need a rubber sheet or rubber gasket, a screwdriver, and a wrench.

How to patch a leaky pipe using a clamp:

1. Turn off the water supply valve to the pipe and drain.
2. Cut a piece of a rubber sheet or pad slightly larger than the leak, and place it over the hole.
3. Wrap the clamp around the pipe and the rubber seal, then tighten the screws with a screwdriver.
4. Use a wrench to tighten the clamp further until the leak stops.

🔧 Pro tip: Be careful not to overtighten the clamp to avoid damaging your pipe.

2. Apply Epoxy Putty

Another approach to pipe repair is epoxy putty, an adhesive that bonds to metal and plastic surfaces when hardened. Epoxy putty works well on minor leaks and is suitable for use on copper pipe and PVC pipe. You can find the putty components at your local hardware store.

You’ll need gloves, sandpaper, and a knife for this fix.

How to patch a leaky pipe using epoxy putty:

1. Cut off the water supply to the leaking pipe and dry the area around the leak.
2. Use sandpaper to roughen up the area around the pipe near the leak, then clean it with a cloth.
3. Put on gloves and knead the epoxy putty until it becomes soft and pliable.
4. Press the putty over the leak and smooth it out with your fingers or a knife, making sure to cover at least an inch around the hole.
5. Let the epoxy putty cure for at least an hour or as instructed on the package.

3. Use Plumber’s Tape

You can also approach patching a leaky pipe with tape. We recommend plumber’s tape, such as Teflon tape or thread seal tape, designed for plumbing applications, which provides a watertight seal around pipe joints. 

Self-fusing silicone tape is an even stronger option: it wraps around the pipe without adhesive, fuses to itself under tension, and creates a waterproof seal on copper, PVC, and PEX pipes.

Duct tape or pipe tape can work in a pinch, but they are very short-term fixes. Duct tape is not designed for plumbing, will not hold under pressure, and should be replaced by a proper repair as soon as possible. 

This tape method is best for small leaks in threaded pipes or fittings.

How to patch a leaky pipe using plumber’s tape:

1. Turn off the water supply and drain the remaining water in the pipe.
2. Wrap the tape tightly around the joint several times.
3. Unscrew the joint and wrap the tape around the threads.
4. Make sure to cover all the threads and press it firmly into place.
5. Screw the joint back on and tighten until secure.

4. Use a Rubber Hose

Another way of patching a leaky pipe involves a rubber hose. You may already have one on hand, and it can work across different pipe materials.

For this method, you’ll also need a hose clamp, scissors, and a knife.

How to patch a leaky pipe using a rubber hose:

1. Turn off the water supply valve and dry the leaky area.
2. Cut off enough hose to cover at least two inches on either side of the leak.
3. Slit one side of the hose lengthwise with a knife so it can open and fit over the pipe.
4. Slide the rubber sleeve over the leak and secure it with hose clamps at both ends to create a tight seal.

5. Use Repair Sleeves

Repair sleeves are another option for a temporary patch on a pipe leak. These are metal tubes that slide over pipes and seal leaks with rubber gaskets or O-rings. Check the pipe diameter before purchasing to make sure the sleeve fits properly around the pipe.

How to patch a leaky pipe using repair sleeves:

1. Cut off the water supply, then drain the remaining water.
2. Use pliers to remove any burrs or sharp edges from the pipe around the leak.
3. Slide the repair sleeve over the pipe until it completely covers the leak.
4. Tighten the nuts at both ends with a wrench until snug, forming a tight seal against the damaged pipe.

6. Apply Self-Fusing Silicone Tape

Self-fusing silicone tape is one of the most reliable options for a temporary repair on leaking pipes because it requires no adhesive. It works by fusing to itself as you wrap it, creating a waterproof seal that holds on copper, PVC, and PEX pipes alike.

How to apply self-fusing silicone tape:

1. Turn off the water supply and thoroughly dry the area around the leak.
2. Stretch the tape slightly as you wrap it tightly around the pipe, starting a few centimetres before the leak.
3. Overlap each layer by about half the tape width as you work your way around the pipe.
4. Continue wrapping a few centimetres past the leak, then press the end firmly to fuse it in place.

This method works well for emergency repairs on leaking pipes in tight spaces and is a solid temporary fix while you wait for a plumber.

7. Use a Slip Coupling

A slip coupling is a more involved pipe repair method suited for a split or badly cracked section of pipe. Unlike the other temporary fixes on this list, using slip couplings requires basic plumbing confidence and the right tools. If you have any doubt, skip this one and call a local plumber.

For PEX pipes specifically, you’ll also need a crimp ring and crimp tool (also called a crimping tool) to secure the internal fitting properly at the correct depth.

How to use a slip coupling for pipe leak repair:

1. Turn off the main water supply valve and drain the line completely.
2. Use a pipe cutter to cut out the damaged section of pipe, keeping the cut pipe end clean and free of sharp edges.
3. Measure the cut pipe length to confirm the slip coupling will span the gap correctly.
4. Slide the slip coupling over the cut pipe on one side, align it, then slide it back to bridge both ends.
5. For copper pipe, solder or use compression fittings to secure slip couplings. For PEX pipes, use a crimp ring and crimp tool at each end, inserting the internal fitting to the correct depth before crimping.
6. Restore the water supply slowly and use a test gauge to check water pressure and confirm the repair is holding.

Important: Slip couplings provide a more permanent fix than the other methods listed here, but any pipe replacement still warrants professional review. For anything beyond a small split, contact a plumber.
