If you have a PVC pipe leak, it needs to be fixed right away to avoid water damage. It is easy for novices to fix a PVC pipe, since it requires no soldering. PVC is strong, but it can spring leaks due to temperature changes. Here are tips to fix a leaking PVC pipe.
Prepare to Work
For this project, you need:
- work gloves
- sponge rag
- emery cloth
- PVC solvent
- PVC glue
- PVC cutters
- PVC fittings
Find the leaking pipe section. Wipe the suspected pipe with a dry rag to find if the leak is on the joint or elbow.
Shut off the water supply to the home by turning the valve clockwise with the crescent wrench. The home's main water supply valve is commonly located near the water meter. Turn on the tap of a faucet close by to relieve water pressure.
Cut the Old Pipe
While you can use a hacksaw, PVC cutters don't leave the fuzzy edges, which may clog small valves on other devices. With the marker, make two marks three inches from the leak on both sides.
Cut the PVC pipe on the marks with the cutters held at a 90-degree angle. Roughen up the ends of the intact pipes slightly by rubbing them with an emery cloth. Dry excess water at each intact pipe end with a rag, so the sealant will hold better.
Install the New Pipe
Cut the new pipe to match the size of the old pipe. Rub the end of the new PVC pipe piece with the emery cloth. Dry fit the parts in the existing pipe, and adjust, if needed.
Check the label on the pipe to determine the correct type of solvent to buy. Do not use solvents on main water lines. Open a window, so you won't breathe solvent fumes. Add the solvent to the inside of the pipe fittings and the exterior of the pipe, using the applicator provided.
Add a thin coat of PVC glue to the inside of the pipe fittings and the outside of the pipe. Dab extra glue with a sponge. Attach the pipe pieces with a twisting motion to help spread the glue in the joint.
Hold the pipe in place for ten seconds, so it won't slip. The glue commonly has to cure for around fifteen minutes.
Check the system for leaks after the glue has dried. If it still leaks, there's a leak in the main water line, or you don't trust your skill, contact a plumber.
