In San Tan Valley, hidden leaks tend to show up as a bill from EPCOR or the Town of Queen Creek that keeps climbing, a meter that turns with nothing running, or a wet spot in the yard or on the floor. A plumber can confirm the loss and narrow it down without guesswork. Call the number on this page to be connected with a local plumber in San Tan Valley.
Most of San Tan Valley grew up after 2000 as planned communities on former desert and farmland, and it became a town in 2025. Water comes from EPCOR across much of the area, the former Johnson Utilities systems, while the Town of Queen Creek supplies water to some neighborhoods. EPCOR also handles wastewater. EPCOR's San Tan system runs on groundwater and reports hardness of 15 to 18 grains per gallon, which is hard on valves, fill valves and water heater fittings.
First steps when you suspect a leak
- Look at the top of your bill to confirm who supplies your water: EPCOR or the Town of Queen Creek.
- Turn off taps, appliances, the softener regeneration and the irrigation controller.
- Watch the meter's leak indicator for a few minutes. If it moves, water is going somewhere.
- Close the house shutoff. A meter that keeps turning points to the yard line or irrigation; one that stops points inside.
- Check each toilet with a few drops of food coloring in the tank.
- If water is pooling at the meter box or in the street, call your provider. EPCOR customer care is 1-800-383-0834.
Matching symptoms to causes
| Symptom | Likely cause |
|---|---|
| Warm tile near the kitchen or a bathroom | Hot water line leaking under the slab |
| Meter moves with the house valve closed | Service line between the meter and the house, or irrigation |
| Faint hiss at night, tank refilling | Toilet flapper or fill valve worn by scale |
| Crust and drips at the water heater | Corroded fitting or relief valve weeping |
| Soft, sunken ground along the side yard | Cracked irrigation lateral or yard line |
What moves the price
- How many isolation tests and which tools it takes to find the source
- Whether the leak sits under a slab, behind a wall or out in the landscaping
- The repair approach: a spot fix, a reroute or replacing a run
- Permit needs, which the new Town handles with building services provided by Pinal County under intergovernmental agreements
EPCOR keeps a service line material inventory you can view at epcor.com/safety, and it reports that lead and copper sampling in its San Tan system met federal standards.
If a leak turns out to be on the line between the meter and the house, ask the plumber whether a repair or a new run makes more sense. In newer subdivisions a single bad coupling is common, while a line damaged by settling soil or landscaping work may need a longer section replaced.
