How do I know if I have a hidden water leak in my San Marcos home?

Signs of a hidden water leak in San Marcos homes include an unexplained increase in your monthly water bill, the sound of running water when all fixtures are off, musty or mildew odors in walls or cabinets, discoloration or bubbling paint, soft spots in walls or flooring, and visible mold growth. If you notice any of these signs, call Phoenician Plumbing for professional leak detection.

How long does leak detection take in San Marcos, CA?

Most residential leak detection jobs in San Marcos are completed in 1 to 3 hours depending on the size of the home and the number of areas to investigate. Complex situations involving multiple suspects or hard-to-access areas may take longer. Phoenician Plumbing schedules same-day or next-day leak detection appointments for San Marcos homeowners in most cases.

Can you detect leaks under my concrete slab in San Marcos?

Yes. Phoenician Plumbing provides slab leak detection throughout San Marcos, CA using electronic leak detection amplifiers and thermal imaging cameras that reveal temperature anomalies caused by water escaping under the foundation. We can pinpoint slab leak locations with precision, reducing the concrete cutting needed for repair.

What causes hidden pipe leaks in San Marcos homes?

Hidden pipe leaks in San Marcos are commonly caused by pinhole corrosion in copper pipes from local water chemistry, failed pipe joints from age or movement, improper original installation, high water pressure stressing pipe walls, and physical damage from renovation work. Homes built before 1990 with original copper or galvanized pipes are most susceptible to hidden leaks.
