A slab leak in San Tan Valley is a water supply line leaking beneath or inside the home's concrete foundation. Most homes get water from EPCOR, some from the Town of Queen Creek, but either way the plumbing past the meter is the owner's.

San Tan Valley at a glance
San Tan Valley was desert and farmland in northern Pinal County until rapid growth after 2000 filled it with planned communities such as Johnson Ranch, San Tan Heights and Pecan Creek South. Voters approved incorporation in 2025, and the new town works with Pinal County, which provides building safety, plan review, permitting and inspection services under intergovernmental agreements. Homes here are mostly built on slabs, and their plumbing is relatively young, which keeps slab leaks less common than in older parts of the Valley but not rare.
EPCOR's San Tan system, the former Johnson Utilities, runs on groundwater and reports hardness of 15 to 18 grains per gallon. That scale is mainly a water heater and fixture issue; EPCOR's report doesn't link it to slab leaks.
What to do now
- Shut down water use. Faucets, appliances, irrigation and any pool fill all off.
- Read the meter. A moving leak indicator means water is escaping somewhere.
- Close the house shutoff. If the meter stops, the leak is inside the home.
- Feel the floors. Walk barefoot near the water heater, kitchen and baths for warm spots.
- Protect belongings. Move rugs and furniture off damp areas and leave the main closed if water is visible.
- Know your provider. Water coming up near the meter or street goes to EPCOR at 1-800-383-0834, or to Queen Creek if it serves your address.
Symptom guide
| Symptom | Likely cause |
|---|---|
| Warm strip of floor | Leaking hot water line in or under the slab |
| Meter moves with the house shutoff open but stops when closed | Leak inside the home, often under the floor |
| Meter keeps moving with the house shutoff closed | Leak in the yard line between meter and house |
| Bubbling or cracked grout in one area | Water pushing up from beneath the slab |
| Hot water runs out faster than it used to | Heated water escaping through a buried line |
What affects the cost
Price depends on locating time, whether the fix is a spot repair or a reroute above the slab, the flooring that has to be opened, pipe material and any water damage to dry out and repair. Permit needs also factor in; in San Tan Valley, those run through the town's arrangement with Pinal County, and the plumber can confirm what applies.
