Fixing slab leak problems in inaccessible areas of the house can be a tiring plumbing job as it may require digging holes through the slab to reach water lines. To make your work easier, you should first conduct a leak detection test to figure out the exact location of the leak.

Detect and Map the Leaking Area

First, you need to locate where the leak could be coming from. That may include listening to all the angle stops throughout the house. Map the loudest area as it indicates where the leak is. Once you have established the leak’s location, you need to figure out the best way to reach and repair it. Rerouting is often recommended. The leaking section is replaced with a new insulated pipe that does not run under your slab but is instead installed above the ceiling. However, rerouting is not always an option, like in two-storied buildings. Alternatively, you can get to the leak from outside by making an access hole and tunneling over. If those options are not possible, you’ll have to dig through the floor to get to the leak. Using a chipping hammer with a wet rag, dig a hole in the mapped area. Remember to lay a plastic sheet outside where you’ll place the dirt from the hole you’re digging to avoid dirt piling up the house.

Locate the Actual Leak

Dig the hole about three to four feet deep to the water lines where you’ll find the leak. If you can’t locate the leak directly, turn on the water and let it flow through the pipes, where you can quickly identify the leak. Remember to switch off the water heater to prevent any electrical problems.

Fix the Leak

Now, fix the leak depending on the type of damage. For instance, if there’s a hole in the pipe, remove that section and slide it apart, place a new piece where it’s leaking, put two couplings and then braise it. Ensure the pipe is steady on the slab to avoid any problems when placing back the dirt and sealing the hole.
