How To Detect A Slab Leak

How To Detect A Slab Leak

The concrete foundation beneath your house is a slab in the plumbing and home services industry. Your home’s water lines run beneath this concrete slab. A leak in these water lines can result from a shift in your foundation (possibly caused by an earthquake or other disaster), poor placement/installation, or general corrosion. Because plumbing slab leaks can occur on either the pressure or drainage side of your foundation, you may notice them on either side of your property.

Tips for Detecting Early Slab Leaks

Floor Splotches

A spot does not always indicate a dry paste that fell on the floor a few days ago. It could tell something serious, such as a leaking slab. Spots suggest that the hot water lines running beneath the slab are broken or have holes. Warm spots are common because hot water accelerates corrosion caused by chemical reactions on the pipe.

Water Bills Have Increased

Your water bill may occasionally increase for no apparent reason. If your consumption rate is consistent and you notice a sudden increase in water bills, you should look into it further because it could be a slab leak. 

Water Rushing Against The Walls

The sound of running water in your walls is a dead giveaway that you have a slab leak. Close all running faucets in the house and listen for any sounds from the walls to determine if this is the source of the problem. Examine the water meter on the wall. If you see the pointer running, this indicates a hidden running source, which could be a slab leak.

Low Water Pressure 

Debris in the water, faulty valves, mineral buildup in the pipes, and water leaks are all common causes of low water pressure. If all other possibilities have been exhausted, the low water pressure will most likely result from a slab leak. Determine all water points in your home to determine the specific cause of low water pressure. Run the water to identify the low-pressure areas.

The Foundation’s Motion

A leaking slab can cause foundation cracks and movement. Water seeps through the slabs and moves downward until it reaches the foundation. It disrupts the overall stability of the concrete and contributes to settlement. Settlement causes movement and cracks due to the house’s instability and overlying pressure. As a result, don’t dismiss any foundation issues.

General Household Issues

Aside from foundation issues, slab leaks cause general house problems. Cracks in the walls and floors and the general odor in the compound and inside the house are examples of such issues.
