Needless to say that even the smallest leak in a pipe can cause damaging effects when not addressed immediately. In fact, a small hole on a PVC elbow can progress to a bigger one when you continue ignoring the problem. Unsightly water stains, flooding, and wood rot can all start from a simple pinhole leak in your pipe. Fortunately, there are easy and simple ways to protect your home from the potential dangers of pipe leaks. In particular, this article will thoroughly discuss how to repair a pin-hole leak in a PVC elbow-shaped pipe.
Before anything else, you have to gather all the materials needed, which will most likely include the following:
- PVC primer and glue
- Caulky gun or epoxy dispenser
- Spare PVC pipe
- Heat gun
- Protective gloves
After preparing the materials, you can now start with the actual leak repair. The first thing to do is to locate the source of the pipe leak, which in this case is the PVC elbow. Turn off the main water valve to impede the flow of water. This is very important to alleviate the damaged PVC elbow pipe from water pressure. Drain the remaining water on the pipe and let it dry before you start repairing the hole.
Next, fill the pinhole with a PVC primer and then followed by the PVC glue. You may also opt to use plumbing adhesives that already combine the primer and glue in one solution, such as the Gorilla PVC glue. Remember that when working with chemical adhesives, it is vital to wear protective gloves.
Apply an epoxy glue stick unto the leaking pinhole with the use of a caulk gun or epoxy dispenser. Allow the epoxy glue to dry before turning on the main water valve. After that, open the water connection and check if there is still any sign of leaks. If the leaking problem persists, you might need to replace the damaged PVC elbow pipe with a new one.
