A PVC pipe leak can cause severe damage to your house if it is not detected early and dealt with, leading to an expensive remodeling job. There are various reasons why a PVC pipe would leak. It could be that the workmanship was poor and left loose ends. Or maybe the glue used was not the correct type for a PVC pipe. It goes without saying that if you do not fix the leak early enough, you will end up straining your pockets in plumbing costs.
Some leaks occur around joints/fittings. In this case, dry the area first. Make sure that the surface is completely dry. You can use a heat gun to ascertain this. After drying, you can apply epoxy putty. Let it cure for some time. Then turn the water back on.
You can also use a compression coupling which is replaced in place of a cutout piece of pipe, where the leak was.
Step 1 - Halt Water Supply
Identify all the points that have leaks while the water is still flowing. Mark these spots using a marker. After noting all the leaking points, you can now turn off the water so that the repairing process can start. Make sure that you do not miss any leaks.
Step 2 - Relieve Pressure
You can then drain any water inside the pipes by opening the taps. It is important that there be no water left in pipes while you are doing the repairs. You can place a pan or basin below the pipe leak to prevent any more damage to the house.
Step 3 - Secure a Piece of Rubber
Neoprene couplers are rubber sleeves that are used to join/fuse two joints of a PVC pipe. Tie a piece of rubber at the point where there is a leak and then place the stainless-steel hose clamp or C-clamp strategically at that point. Adjust the clamp’s tightness using a screwdriver.
Step 4 - Wrap Fiberglass Tape around the Leak
Water makes the fiberglass tape soft. Tie the tape around the leaking point and ensure that the leak is completely sealed. If there is any visible leak, use more tape to stop it. Do not forget to use gloves for hygiene purposes. Let the tape stick to the pipe for a while. Give it 5 to 10 minutes then let the water flow back through.
Have tools ready before you commence the repairs. Collect everything that you need beforehand. Be careful to avoid injury. Hot water from the pipes can cause inflict serious injury, take extra care. PVC glue is acidic and if it lands on your skin, it is bound to burn so be sure to use gloves when gluing anything.
