Using Plumbers Epoxy Putty

Find the leaky section of the pipe. You will notice visible drops of water around the leaky pipe. Turn off the main water valve and use a rag to dry the leaky area.

Then, use sandpaper to smooth out any destruction or rust on the damaged pipe before cleaning and getting ready to apply the epoxy putty.

Epoxy putty is usually in two parts mixed to produce a reaction that creates the adhesive and toughening agents. Follow the package instructions on how to prepare it correctly. Don’t forget to put on latex gloves when handling the putty.

Once the putty is ready, apply it to the damaged basement pipe. And be sure to press it over the pipe leak to form a tight seal.

Allow the epoxy to dry for about an hour before turning the valve back on. Make sure that the putty remains in place and that you can’t detect any more leaks.

TIP: You may consider using a propane torch to heat up the pipe after drying it to help accelerate the curing/drying process of the epoxy. You may also consider wrapping up the repair area with duct tape.

2. Using Repair Clamps

Using Repair Clamps

The clamp used here is essentially a pre-rolled sheet of stainless steel with a rubber lining inside that is held in place with soldered bolts and nuts.

The clamp tensile force is transformed to direct pressure on the inner rubber layer, forming a secure seal around the leaky pipe.

To use a repair clamp to fix a leaky pipe, quickly place its rubber-lined part over the exact position where there’s a leak on the pipe before you tighten the screws and nuts that hold the clamp in place.

Once in place, tighten the screws and nuts of the pipe repair clamp. It will form a seal over the leaky area. A decent pipe repair clamp will last for many years if you use it properly.

3. Using Tape

You can also use tape to stop water from leaking from pipes in the basement. Depending on the pipe you’re working on, several kinds of tape, such as Teflon tape, duct tape, and electrical tape, could be effective at containing a minor leak.

The key to temporarily using tape to repair a leak is to make sure the leaky pipe is completely dry while taping, as it will help you create a good seal.

You should also completely compress the tape on the pipe to avoid water pockets forming inside your tape job. Please note that this method will only work on minor leaks, and you should not attempt to use it on significant leaks.

4. Using Coupling Connectors

Slip couplings are another effective way to fix a leak in your basement. They’re usually small, water-right connections and securely join two pieces of pipe to stop leaks.

If you go with this method, be sure to select a slip coupling that is appropriate for the size or type of your pipe.

Search for a slip coupling that is the same size as the pipe that needs to be repaired and is long enough to allow you to cut off the leaky part.

Before buying one, also ensure that it is made of the same material as the leaky pipe that you plan to repair, which could be PVC or copper.

Remember that these slip couplings offer a lasting solution for your leaky pipes and are also code compliant.
