San Tan Valley was largely built after 2000, so most homes need a leak repair rather than a full repipe. A repipe makes sense when one house keeps springing leaks in different places or the same fitting type fails again and again.

San Tan Valley basics
This former desert and farmland in northern Pinal County filled in quickly with planned communities such as Johnson Ranch, Pecan Creek South and San Tan Heights, and it became an incorporated town in 2025. Water comes from EPCOR across much of the area, through the former Johnson Utilities system, while the Town of Queen Creek supplies water to some neighborhoods. EPCOR's San Tan system runs entirely on groundwater and reports hardness of 15 to 18 grains per gallon, which is hard enough to scale up valves and fittings over time.
What to do now
- Shut off the main if water is actively leaking. Most homes here have a shutoff near the front hose bib or in the garage.
- Look at the pipe where it is exposed, usually at the water heater and under sinks, and photograph it along with any fittings that look corroded.
- Turn every fixture off and watch the meter for a few minutes. Movement means water is escaping somewhere.
- Find your water provider on your bill. Homes on EPCOR and homes on Queen Creek water use different reports and contacts.
- Call for an assessment, and ask whether a repair, a section replacement or a full repipe fits the pattern you have seen.
Symptoms and what usually causes them
| Symptom | Likely cause |
|---|---|
| One drip at a crimp or fitting | A single faulty connection |
| Several leaks at the same fitting style | A product or installation problem across the system |
| Hot floor tile and a running meter | A leak on a line under the slab |
| Stiff valves and white crust at joints | Scale from 15 to 18 grain water |
| Stain in a ceiling below a bathroom | A leak at a fixture connection or a line in the ceiling |
Cost factors
- Whether you replace one problem section or every supply line
- Attic space for running new lines over a slab home
- Number of bathrooms, the kitchen, laundry and outdoor spigots
- Drywall and texture repair after the work
- Permits: the new Town of San Tan Valley handles building processes, with Pinal County providing permitting and inspection services under intergovernmental agreements
