Signs You Need Service
Watch for these common issues indicating professional attention is needed.
What Is Behind These Problems
Underground Copper Pinhole Pitting
Possible causes: Chemical reactions between water minerals, soil acidity, and copper tubing create microscopic pinholes under concrete slabs.
What to check: Shut off all taps and observe the water meter leak indicator.
When to call a plumber: When water bills soar or floors develop warm, damp patches.
Failing Concealed Pipe Joints & Fittings
Possible causes: Thermal expansion, excessive water pressure, or poor solder joints cause elbows and couplings inside walls to weep.
What to check: Check around baseboards and crawlspace framing for moisture staining.
When to call a plumber: When moisture meters or thermal cameras detect cold or warm plumes behind walls.
Soil Shifting & Pipe Shearing
Possible causes: Expansive clay ground movement exerts lateral shearing forces against buried water service laterals entering the home.
What to check: Inspect front yard lawns for soggy depressions or unusually green grass.
When to call a plumber: When main incoming pressure drops or yard soil becomes saturated.

Charleston Leak Repair Questions
How do plumbers find hidden water leaks without tearing up floors?
Plumbers use electronic acoustic listening gear, ground microphones that amplify sound frequencies of pressurized escaping water, thermal imaging cameras, and tracer gas detectors to pinpoint leak locations non-invasively.
What is the simple water meter test for leaks?
Shut off every tap and water-using appliance in your home. Go to your water meter box. If the low-flow indicator dial (often a small triangle, star, or digital gallon sweep) is spinning, pressurized water is escaping somewhere on your property.
Will my homeowners insurance cover leak detection and repair?
Many insurance policies cover the cost of locating the leak and repairing resulting water damage to floors and walls, though repairing the plumbing pipe itself is typically the homeowner's responsibility. Verify with your carrier.
What is the difference between a spot repair and a pipe reroute?
A spot repair involves opening concrete directly above the leak to repair the section. A reroute abandons the damaged underground line entirely and routes a new, seamless PEX line through walls and ceilings, avoiding floor demolition.
How urgent is a slab leak?
Very urgent. Leaking pressurized water erodes supporting soil beneath your foundation, creating voids that can cause foundation cracking, structural shifting, and thousands of dollars in property damage.
