How to Repair a Broken Pipe Inside Your Wall

As a homeowner, the last thing you want to deal with is a burst pipe inside a wall. Thankfully, your broken pipe can be repaired, and the source of the damage can be addressed. To find a broken pipe inside a wall and repair or replace the broken part, you’ll need the necessary tools, skills, and knowledge.

What Causes a Pipe to Break Inside a Wall?

Freezing weather is the major cause of pipes bursting inside walls. When the temperature drops below a certain level, the water inside the pipes expands and comes dangerously close to freezing. When the pressure builds up, the pipe structure cracks, which occurs more frequently when the temperature dips below -6 degrees.

What Are the Signs of a Broken Pipe Inside a Wall?

Depending on where the pipe is broken and the extent of the fracture, the signals that your pipe inside the wall is damaged may go undiscovered or be all over the place. The following are examples of warning signs:

Mold

An excessive amount of moisture encourages mold growth. Mold could be a problem in your home. If, on the other hand, mold is growing at an exponential rate for the first time, the cause could be a broken pipe within your walls.

Find the Location of the Pipe

Inside the walls, water from a broken pipe often pools somewhere below where the pipe is truly broken. Follow the indicators of water damage, such as drywall damage, until you identify the source of the leak. Consider utilizing a moisture meter if you can’t determine the source visually.

Most notably, avoid cutting into the wall studs by locating them first. When knocked, studs usually make a solid sound and are frequently found near power outlets and switches.
