When you develop a leak in a PVC pipe or fitting, you cannot always cut the pipe to install a splice. While the process of repairing a leak without cutting is labor-intensive and will take longer to complete, the result will last as long as a splice and not require any additional sealing.
Things You'll Need
- Grease pencil or marker
- PVC plugs
- Vacuum cleaner
- PVC primer
- PVC glue
Locate the leak in the PVC pipe and mark with a grease pencil or marker it so you can locate it later. It's easier to locate the leak if you still have water or fluid running through it. Turn off the supply of fluid to the PVC pipe via the shut-off valve if the PVC pipe is a supply line. If the PVC is part of the drainage system, don't run water into the drains during the repair.
Cover or plug all holes in the pipe--drains or access holes--using the drain stoppers built into the sink's drain. You can also push PVC stoppers or rubber plugs into open holes in the pipe. You must have the ability to create a suction inside the pipe. Leave one access hole or drain unplugged.
Place the end of a wet/dry vacuum hose over the open hole in the PVC pipe and turn it on. This will create suction inside the PVC pipe.
Dip the supplied brush into the PVC primer and place the brush over the leak in the pipe. The suction will pull the primer into the crack, removing dirt and fluid in the crack.
Dip the supplied brush supplied into the PVC glue and place the brush over the leak. Again, the vacuum will suck the glue into the crack. Shut off the vacuum once you see the glue suck into the crack. Allow 30 minutes to cure before removing the plugs and running fluid through the pipe.
Repeat the process if you still have leaks in the PVC pipe.
