How to Fix a Pinhole Leak in Pex Pipe

Summary: If you see water or gas coming out of your pex pipe, there is a good chance that you have a pinhole leak. To fix this leak, you will need to remove the damaged section of pipe, seal the hole with a patch, and then replace the section of pipe.

Five Reasons That Causes Pinhole Leaks in Pex Pipe

1. Improper Installation of the Piping

Improper installation of the piping is one of the most common causes of pinhole leaks in Pex pipe. This happens when the piping is not installed correctly and causes small cracks that can lead to a pinhole leak.

2. Corrosion

Pex pipes are prone to corrosion over time because of their metal content. This can cause small holes to form, which will eventually leak. If you suspect that your Pex pipe has begun to corrode, you can test it by pouring a vinegar and water solution over the pipe. If the pipe fizzes, it is corroded and needs to be fixed. To fix a corroded Pex pipe, you will need to cut out the corroded section and replace it with a new pipe.

3. Kinking

If your Pex pipe has a kink in it, this can cause a small hole to form and eventually lead to a leak. To test if your pipe has a kink, fill it with water and look for any leaks. If there are leaks, the pipe has kinked and needs to be fixed. To fix a kinked Pex pipe, you will need to remove the kink and replace the section of the pipe.

4. Freezing:

If the Pex pipe freezes, it can crack and eventually leak. To prevent this, take precautions such as installing insulation around the piping if you live in a climate where the temperature often drops below freezing. If your Pex pipe has already frozen and cracked, you will need to replace the section of the pipe.

5. Pipe Is Crimped Too Tightly

The Pex pipe can get a small hole in it if it’s crimped too tightly. This hole will cause the pipe to leak. To fix the pipe, you need to loosen the crimp and replace the section of the pipe that has the hole.

10 Ways on How to Fix a Pinhole Leak in Pex Pipe

1. Use a Clamp or a Sleeve

A clamp or a sleeve can be used to fix a pinhole leak in Pex pipe. Slide the clamp or sleeve over the pipe and tighten it until the leak is fixed.

2. Apply Pipe Tape

If a clamp or sleeve isn’t available, you can use pipe tape to fix the leak. First, wrap the pipe tape around the leak area and then apply pressure. The pipe tape will create a seal and stop the leak.

3. Use a Hose Clamp

A hose clamp can also be used to fix a pinhole leak in the Pex pipe. This is a less common method, but it can be effective in certain situations. First, use a screwdriver to remove the screw from the clamp. Next, slip the clamp over the leaky section of the pipe and reattach the screw. Finally, tighten the screw until the clamp is snug against the pipe. This will help to seal the leak.

Hose Clamp Can Also Be Used

4. Use a Rubber Band

If you don’t have a hose clamp or a sleeve, you can use a rubber band to fix the leak. Stretch the band around the leak and hold it in place while you twist the pipe with your other hand. The band will create enough pressure to seal the leak.

5. Use a Sleeve

If you have a hose clamp or sleeve, you can use it to fix the leak. Slip the hose clamp over the pipe and tighten it until the leak is sealed. If you don’t have a hose clamp, you can use a piece of electrical tape or duct tape to seal the leak. If you have a sleeve, you can also use it to fix the leak. Slip the sleeve over the pipe and tighten it until the leak is sealed.

6. Use a String

If you don’t have any of the above options, you can use a string to fix the leak. Tie one end of the string to an object that is close to the leak. Bring the other end of the string to a faucet and turn the water on. When the water pressure is strong enough, it will push the string into the hole and fix the leak.

7. Use a Zip Tie

If you have a zip tie on hand, this is a quick and easy way to fix a pinhole leak in the Pex pipe. Cut off a section of the zip tie long enough to fit around the pipe, then use the pliers to crimp it tightly around the leak. The zip tie will help to seal the hole and stop the leak.

8. Try a Duct Tape Patch

If you don’t have a zip tie on hand, you can also try using duct tape to patch the hole in the pipe. Cut a piece of duct tape that is big enough to cover the hole, and stick it to the pipe. Ensure that the duct tape is securely stuck to the pipe, and that there is no leakage.

9. Use a Heating Pad

If the leak is small and you can’t seem to get it to stop, you can try using a heating pad. Place the heating pad over the area of the leak and hold it in place with some tape or a bandage. The heat will help to seal the leak and stop the water from coming out.

10. Use a Hair Dryer

If the pinhole leak is small, you can try to fix it yourself by using a hairdryer. First, heat up the area around the leak until it’s hot. Then, put a piece of plumber’s tape over the hole. The heat will cause the tape to stick to the pipe.
