How to Fix PVC Pipe Leak
When leaks occur in the PVC joints, replacing defective pipes or fittings requires only a few tools and the right replacement parts.
Step 1. Locate the Leak
Whether a beginner learning how to fix PVC pipe leak or a seasoned veteran, the one thing that you need to be familiar with when it comes to locating a leak in a PVC pipe is that the source of the leak could be further away from where you think it is. Water will travel along the PVC pipe a long distance from the actual source of the leak before falling and appearing as a drip. Start by wiping down the area near that suspected leak with a clean dry cloth. Afterwards, look carefully again for the source of that leak.
Step 2. Replace the Pipe
Now that you have determined the exact location of the source of the leak, you can focus on how to fix leaking PVC pipe joint. Determine which part of the pipe needs to be repaired or replaced. Unfortunately, when it comes to the cheaper PVC material, there’s no simple fix for removing the damaged PVC pipe from any glued fittings.
If the leak has been determined to be at the joint, the easiest way to make this repair is removing the affected section of PVC pipe. You should also get rid of any of the adjoining fittings.
Step 3. Turn off the Water
The first thing to make sure of when learning how to fix leaking PVC pipe joint is to turn off the water supply to the affected pipe. If you have doubts that the valve turns off the water to the area that you will be working, locate the main water supply and turn it off there instead.
Step 4. Remove Damaged PVC Pipe
Use a good pair of PVC cutters to remove the damaged section of plumbing. If the leak is obvious, try to cut at least one inch on either side of the leak. This way, you make sure all the damaged area is removed.
By taking more than you really need to cut away, it helps to decrease the likelihood that this leak will reappear. Place the PVC cutter at the desired spot, hold the cutting jaws at 90-degrees, then make a straight cut through the pipe at least one inch on each side of the leak. Once the section of damaged pipe is removed, allow all of the water in both sides to properly drain. Dry both locations with a clean cloth.
Step 5. Dry Fitting New Pipe
Before we rush into replacing the damaged pipe, take a minute to loosely assemble the new PVC replacement pipe into position. In terms of how to fix leaking PVC pipe joint, dry fitting the piece into place. This step gives you the opportunity to make any adjustments before the priming and gluing begin.
The old saying about measuring twice and cutting once applies here perfectly. This is your chance to make all the adjustments before we reach that point of no return. Once the replacement PVC pipe is fitting perfectly in place, disassemble the pipe so it can be properly prepared for the primer and then the glue.
Step 6. Apply PVC Primer
Open the container of PVC primer. With the applicator brush, begin applying the solvent to the outside of the replacement pipe and the inside of the old fitting. This solvent primes the PVC so that the cement can better adhere. The primer will remove the shiny surface of the PVC pipe. It will create a matte-like finish that will allow the cement to work properly and begin the chemical process needed to create a secure bond.
Step 7. Apply the PVC Cement
Now that the pipes have been primed, it is time to apply the PVC cement. Repeat the same process as with the PVC primer. Use the applicator brush in the cap of the PVC cement to apply a generous amount to the inside of the fitting and the outside of the replacement pipe edges.
Start inserting one end of the replacement PVC pipe into the fitting by using a twisting and pushing motion. Not only will this get the pipe into the fitting, but it will also spread the cement to every inch of the joint. This allows the pipe to be lubricated so it slides in all the way into the neck of that fitting. Once the joint is together, hold it firmly for 15 seconds to ensure it does not slip out of place.
Step 8. Repeat the Assembly Process
Now that one end of the PVC pipe has been repaired, do the same for the other side. Continue until the damaged section is replaced with all new PVC pipe. The glue on each of the contact points should be allowed to cure for at least 15 minutes. Nonetheless, read the recommendations of the manufacturer on the label. These are the most important steps on how to fix leaking PVC pipe joint. Take it slow until everything is set and can not be moved.
In warmer locations, it might take longer for the cement to dry, so adjust the numbers accordingly.
These tips on how to fix leaking PVC pipe joint are easy if you take your time and slowly fit everything into position before primer and glue dries. Restore the water pressure and check for leaks. Everything should be dry and the repair complete by now. If you have any tips or tricks on how to fix leaking PVC pipe joint, please feel free to share your experience.
