How to fix broken pvc pipe in concrete

PVC pipes are a common choice for plumbing and irrigation systems due to their durability and cost-effectiveness. However, even the strongest PVC pipes can become damaged or broken, mainly if buried in concrete. If you have a broken PVC pipe in your concrete slab, it can be frustrating and costly to repair. However, with the right tools and some know-how, you can fix the problem yourself.

Here is a step-by-step guide on how to fix a broken PVC pipe in concrete:

Locate the broken pipe

The first step in fixing a broken PVC pipe is to locate the exact location of the break. It can be challenging if the pipe is buried deep in the concrete slab. One way to locate the break is to turn off the water supply to the pipe and then check for any leaks or wet spots on the surface of the concrete. You can also use a pipe locator tool, which sends a signal through the pipe and allows you to locate the break using a receiver.

Cut out the section of the pipe that is broken

Once you have located the break, you will need to cut out the damaged pipe section. You can use a circular or reciprocating saw to cut through the concrete and expose the pipe. Wear protective gear, including goggles, gloves, and a dust mask, to avoid injuries.

Remove the damaged section of the pipe

Once you have exposed the broken section of the pipe, you will need to remove it. You can use a pipe cutter or a saw to cut the pipe into manageable pieces and then carefully remove the pieces from the concrete slab.

Measure and cut a new section of pipe

To fix the broken pipe, you must replace the damaged section with a new piece of PVC pipe. Measure the section length that you need to replace, and then cut a new piece of pipe to fit. You can use a pipe cutter or a saw to cut.

Glue the new section of pipe in place

You will need to use PVC cement to attach the new section of pipe to the old pipe. Follow the manufacturer’s instructions for applying the cement, and use enough to create a strong bond. Allow the cement to dry for the recommended amount of time before continuing.

Cover the repaired section of the pipe

Once the new section of pipe is in place, you will need to cover it with concrete to protect it from damage. Use ready-mix concrete or mix your own using cement, sand, and water. Follow the manufacturer’s instructions for mixing and applying the concrete, and smooth it out to match the surrounding surface.

Test the repaired pipe

After the concrete has had time to set and dry, you can test the repaired pipe by turning the water supply back on. Watch for leaks or issues, and make any necessary adjustments to ensure the repair is secure.
