The sound of running water, when no water should be running, could indicate a slab leak.
If you hear running water in your home when all should be quiet, means there is flowing water somewhere.
Your home’s plumbing is pressurized and static when all appliances and faucets are in the off position. The sound of running water is created by the vibration of the flow of water against the piping system. It means an outlet from the system is allowing flow. You will need to check all faucets, toilets, sprinklers, as well as water connected appliances like refrigerators, clothes washers, dish washers, or water purification systems.
If you don’t find visual clues to the source of the sound of water, it could mean you have a hidden leak in the wall or under the slab.
Hot water lines are usually insulated and don’t heat the floor unless it was built as a radiant heating system.
If you have pets, you may notice they gravitate to a certain spot on the floor. Check to see if it feels warmer than usual.
Cracks in walls or floors could be damage from a slab leak.
There are several possible factors in the appearance of cracks in walls and floors. If you live in a seismically unstable area, it could instead have to do with shifting ground due to earthquakes.
Even if ground shifting is due to unstable ground, it could also mean the area under your property has been compromised by water flow from a leak under your slab. If untreated, a water leak could create a massive void under the foundation. This void can put stress on the foundation, and increased stress on the foundation can cause cracks in the floors and walls.
Mildew or excessive moisture under carpets could indicate your slab is cracked and the pipes inside are leaking.
Cracks in a slab due to a leak allow moisture into the flooring. Drywall will wick the moisture up, and create an ideal environment for mold to grow behind the wall. Mold is an environmental hazard and you need to make sure that proper clean up and restoration of the property is performed. Before the restoration is performed, the mold needs to be removed. Then, the location of the source of moisture that feeds the mold can be identified and repaired.
High water bills could indicate a leak. Although a high water bill could indicate a water leak behind the wall or in your pool, plumbing under the slab is also suspect.
Unusually high water bills could occur for several reasons. Sometimes the meter is not working properly and needs to be replaced. You will need to contact your water authority for this kind of issue.
If your meter is working properly, then it comes down to usage.
Conduct the meter test to see if your toilets are leaking or if you have a hidden water leak.
