Repair a Small Leak with Epoxy Putty
Epoxy putty can provide an effective way to fix a small leak. It holds up well and it is relatively easy to use and install. Follow this simple guide to plug leaks, whether in pipes or walls.
Step 1 - Locate the Leak
Before you can apply any fix, you have to find the source of the problem. Run a dry paper towel along the edge of the area you think is leaking. Remove the paper towel periodically and take a look at its surface. If there are signs of wet spots, you have narrowed down the location of the leak. Continue with this process until you have uncovered all the leaking areas.
Step 2 - Mark the Leaks
Once you have found the leaks, clearly mark them with a pencil or marker. This will help you when you go to seal the leak.
Step 3 - Turn off Water
Turn off the water supply to the house. Go to the primary water main that is responsible for bringing water into the house and shut it off (you can shut the valve off at the source or if you have flexible piping).
Step 4 - Sand the Pipes
Use sandpaper to sand down the pipes. Clean the pipes after you have completely sanded them. You want to make sure the pipes do not have any debris or grit on them from the sanding. If you have copper water lines, they should be shiny in appearance. If you have PVC piping, it should look roughed up from the sanding.
Step 5 - Cut the Epoxy
Step 6 - Press Epoxy onto Pipe
- Never allow the epoxy to sit over a long period of time. You should ideally use the epoxy within 3 to 4 minutes after it has been mixed.
- Do not turn your water back on until the epoxy has cured. It may take a couple hours for it to set properly
