In much of San Tan Valley, EPCOR handles wastewater, and the drain pipes inside your home plus the line out to EPCOR's main are the owner's to maintain. A plumber clears the clog on your side and can tell you if the trouble goes past it. 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 from desert and farmland in northern Pinal County into a large collection of planned communities, most of it after 2000, and it became an incorporated town in 2025. The housing is mostly newer slab construction with plastic drain lines, so clogs usually come from use rather than worn pipe. EPCOR runs the San Tan Wastewater district, the former Johnson Utilities system, and treats wastewater at its enclosed Copper Basin Water Reclamation Facility. Some neighborhoods get water from the Town of Queen Creek instead of EPCOR, but Queen Creek provides water only there, not sewer. EPCOR's San Tan water measures 15 to 18 grains per gallon of hardness, so soap and mineral film in bathroom drains is common.
What to do now
- If two or more drains are backing up, stop using water everywhere in the house.
- Turn off the supply valve behind a toilet that is filling toward the rim.
- Look at the outdoor cleanout near the foundation. Water at the cap means a main line clog.
- Move towels, rugs and anything stored near the tub or shower that may take on water.
- If sewage is coming out of a manhole or the street rather than your own drains, contact EPCOR.
- Leave chemical openers on the shelf and call a plumber.
Symptoms and what they usually mean
| Symptom | Likely cause |
|---|---|
| Shower drains slowly, others fine | Hair and soap film in the shower trap |
| Kitchen sink fills from the other basin | Grease or food lodged in the kitchen line |
| Toilet gurgles when the washer drains | Partial blockage in the main or a venting issue |
| Water at the outdoor cleanout | Main line blocked between the house and EPCOR's main |
| Recurring clog every few months | Sag, offset joint or roots; a camera confirms |
What affects the cost
Price turns on where the blockage is, how easy it is to reach and which tools the job needs. A sink trap cleared from under the counter is a short visit. A main line opened from the cleanout takes a larger machine, and jetting or a camera inspection usually adds to the bill. If the plumber finds a broken section that has to be replaced, that becomes a permit job; Pinal County provides building safety and permitting services for the new town under an agreement with the Town of San Tan Valley. Evening and weekend calls generally cost more.
