Much of San Tan Valley is on EPCOR's groundwater system, which reports hardness of 15 to 18 grains per gallon, so faucet cartridges and aerators here scale up quickly. A drip or stiff handle is usually a parts repair. Call the number on this page to be connected with a local plumber in San Tan Valley.
San Tan Valley at a glance
San Tan Valley grew fast after 2000 out of northern Pinal County desert and farmland and became a town in 2025. Because so much of it was built in a short span, many neighborhoods have faucets of similar age, and they tend to need attention around the same time. Most homes sit in planned communities such as Johnson Ranch, Pecan Creek South, San Tan Heights and Archer Meadows. Water depends on the address: EPCOR's San Tan district, the former Johnson Utilities, provides water and wastewater across much of the area, while the Town of Queen Creek provides water only to some neighborhoods. EPCOR's San Tan system runs entirely on groundwater, uses chlorine, and reports hardness of 15 to 18 grains per gallon.
Steps to take now
- Close the stops. Turn the valves under the sink clockwise until the faucet stops. If they are stuck, shut the main.
- Look before you call. Note whether water comes from the spout, under the handle, at the base or under the sink.
- Clear the aerator. Unscrew it and rinse out scale; in water this hard, it may be the whole problem behind weak flow.
- Check the softener. If you have one, make sure it has salt and is regenerating. A softener that quit is a common reason scale suddenly gets worse.
- Find the brand. A logo or model number helps the plumber bring the right cartridge.
Symptom guide
| Symptom | Probable cause |
|---|---|
| Spout drips with handle off | Cartridge seals worn or scaled |
| Handle stiff or gritty | Mineral buildup in the cartridge |
| Leak at the spout base | Spout O-rings worn |
| Spray head drips | Worn hose seal or check valve |
| Stream weak at one sink | Aerator or cartridge clogged with scale |
| Water under the sink | Supply nut, hose or drain connection |
What affects the price
- Cartridge or seal repair versus a new faucet
- Scale that has seized parts, common in water this hard
- Availability of parts for builder-grade models
- Replacing old stops and supply lines at the same time
- Permits for larger plumbing changes: the Town now handles building processes, with Pinal County providing permitting and inspection services under agreements, so the plumber can say whether your job needs one
