Slab Leak Warning Signs in Older Pennsylvania Homes
Short answer: A meter that moves with every tap off, a warm streak in the slab, and the sound of water with fixtures closed are enough to call for leak location - not a whole-floor demo.
Not every Pennsylvania home has a true slab plumbing grid. Many Johnstown houses have buried supply beside the foundation that gets called a “slab leak” in search. We still locate it the same way.
Meter test
Shut every fixture. If the low-flow indicator still ticks, water is leaving the system. Next stop: slab leak detection.
Do not ignore a warm floor in winter
A heated streak that is not a radiator pipe is often a pressurized leak. Cutting randomly is how tile jobs explode in cost.
After we mark it
Spot repair versus reroute depends on access and pipe material. We explain both on site.
