How to Patch a Leaking Flexible Plastic Pipe
Repairing a leak in your flexible plastic pipe can be costly. Allowing a leak to continue with temporary fixes can cause increases to your utility or water bill and cause other other costly repairs. With the proper instructions and material, you can repair a leaking pipe yourself and save a significant amount of money in the process.
Step 1 - Mark the Leak
Put on your safety glasses and gloves and find the area of the pipe where the leak is. Use your sharpie to mark the spot on the opposite side of the leak.
Step 2 - Shut off Water Supply
Locate the water supply shut-off valve and turn it clockwise to prevent the water from flowing as you conduct repairs on the pipe.
Step 3 - Place Bucket Beneath Leak
Use your small bucket to place beneath the area of the spot you marked on the pipe. This will allow you to keep your floor as dry as possible as you move on to Step 4.
Step 4 - Cut Pipe With Hacksaw
With the hacksaw, cut the pipe 2 inches on both sides of the mark you made with the sharpie. Allow excess water to drain into the bucket as you are cutting.
Step 5 - Scrape Away Debris
Take the utility knife and scrape away any debris from the surface of the pipes and smooth out the edges of where the cuts were made on both ends of the pipe.
Step 6 - Thoroughly Dry Both Ends of the Pipe
With your dry rag, wipe away any moisture from the pipe on both ends that may have been left from the water. Ensure the pipe is thoroughly dry to enhance the effectiveness of the PVC cement.
Step 7 - Check the Fit and Measure
Use the PVC couplers to check the fit by placing one of each on each end of the pipe. Do not cement the couplers at this time. Measure from the middle of one coupler to the middle of the other coupler on both ends of the pipe. This will determine how much PVC pipe you will need for the repair.
Step 9 - Cut PVC Pipe
In accordance to the measurements made in Step 8, use your hacksaw to cut the 8 foot section of PVC pipe to specifications. Use the utility knife to smooth out the edges.
Step 10 - Apply PVC Cement
Apply PVC cement to the outside of one end of the cut pipe and the outside end of the repair pipe and then to the inside of both ends of one of the couplers. Place the coupler on one end of the damaged pipe and insert repair pipe in the other end. Repeat this process at the other end. Allow the cement to dry for not less than 2 minutes. Turn on water and check for leaks.
