Most San Tan Valley homes get water from EPCOR's San Tan system, which relies entirely on groundwater, while some areas are served by the Town of Queen Creek. Either way the wells belong to the utility, so a household well pump is uncommon here and pressure trouble usually starts at the regulator, a leak or scale. Call the number on this page to be connected with a local plumber in San Tan Valley.

San Tan Valley in brief
San Tan Valley grew from desert and farmland into a string of planned communities like Johnson Ranch, Pecan Creek South and San Tan Heights, and became an incorporated town in 2025. Water service depends on the address. EPCOR runs the former Johnson Utilities systems as its San Tan Water and Wastewater districts, with about 31,000 water connections fed solely by groundwater. The Town of Queen Creek provides water, but not sewer, to some San Tan Valley neighborhoods. EPCOR reports hardness of 15 to 18 grains per gallon, which is high enough to leave visible scale.
What to do now
- Find your bill. EPCOR or Queen Creek means you are on a public system with no pump of your own.
- Check with a neighbor. If the street is dry too, report it to your provider; EPCOR's customer care line is 1-800-383-0834.
- With every fixture off, look at the meter. If it is still turning, there is probably a leak between the meter and the house or under the slab.
- If only one tap is weak, unscrew and rinse its aerator. Scale from hard groundwater collects there first.
- If you have a private well or a booster pump, check its breaker and the tank gauge, and leave the wiring and wellhead closed.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Whole house slowly lost pressure | Regulator wearing out or scaled up |
| Sudden drop, higher water bill | Leak on the service line or under the slab |
| Shower or faucet sputters | Scale in the cartridge or aerator |
| Pump clicks on and off quickly | Pressure tank lost its air charge |
| Pump hums but nothing flows | Bad capacitor, seized motor or a dry well |
What moves the cost
- Whether the fix is a fixture, a regulator, a buried line or pump equipment
- Where the leak sits: under a yard, a driveway or the slab
- How much scale has to be cleared from valves and cartridges
- For a private pump: depth, tank size and the condition of the controls
- Permits: the Town took over building processes from Pinal County, which still provides plan review, permitting and inspection services under agreements with the Town
The call is free and goes through a referral service, not a plumbing company, to an independent plumber who works in San Tan Valley.
