If you have a leak in your plumbing you may want to use coupling to fix it. Coupling covers the leaking section of pipe with a new pipe that can be tightened or sealed into place. PVC coupling is the most common.
- Shut off the water source and drain the water from the pipes you will be working with.
- Cut a piece of PVC piping off where the leak is at least a foot long. There are special tools to help you make a clean cut, but a hack saw will also work.
- Clean the ends of PVC piping, the replacement piping, and the coupling with PVC cleaner. This is a special type of cleaner that will help the glue adhere.
- Your replacement piping should be at least 12 inches long so there is room for the couplings. It should also be 1/4 inch smaller than the missing piece.
- Use PVC glue on the edges of all of the pipes and slide on a coupling on both sides of the new piping.
Coupling Drying Time
PVC glue is fast drying and it should only take about 30 minutes to dry. Turn the water back on and check to see if there are any leaks around the coupling.
