Plumbers in Sun City, AZ

Sun City is a Census-designated place, not an incorporated city, so there is no city water department or city building office. Water here comes from EPCOR, a private utility. Its 2025 water quality report says the system serves nearly 24,000 connections here and in the Town of Youngtown, using groundwater pumped from the West Salt River Valley sub-basin. If you are not sure who supplies your address, check the name on your water bill or EPCOR's Find your district map.

There is no city sewer utility either. EPCOR says homes in the community that receive wastewater service from it fall under its Sonoran Wastewater District, and it describes an ongoing program of video inspections of sewer mains and manholes in the Sun Cities. For an outage or other water trouble, EPCOR takes reports at 1-800-383-0834, 24 hours a day. Leaks, clogs and water heater faults inside the house are plumbing work, and that is where our team comes in.

Census estimates count 26,626 homes in the community, with a median build year of 1973. About 58% were built in the 1970s and another 29% in the 1960s; in all, roughly 94% predate 1990. About 84% of occupied homes are lived in by their owners, and the average household is 1.63 people. A home built in 1973 has had its plumbing in service for more than 50 years, so it pays to know which parts are original and which have been replaced.

Permits run through Maricopa County, not a city. The County's Planning and Development Department regulates development in unincorporated areas. Its permit page says a permit is no longer required to replace an existing water heater when the work follows the manufacturer's specifications, and it lists water, sewer and gas line repair among its web-issued permits. The County also reminds owners to review their HOA's CC&Rs before modifications. Trident is licensed in Arizona under ROC 331536.

EPCOR's 2025 report puts hardness at 7 to 11 grains per gallon. On EPCOR's own scale, 7 to 10.4 counts as hard and anything above 10.5 as very hard. Calcium in its samples ranged from 25 to 42 parts per million and magnesium from 13 to 20. EPCOR states that it does not treat drinking water for hardness, and it says the white deposits left on dishes and faucets are calcium carbonate in most cases.

Those minerals settle in tank bottoms, coat tankless heat exchangers and crust aerators. A softener reduces scale at the source, while filtration handles taste and drinking water. EPCOR's report also warns that skipping maintenance on a home softener or reverse osmosis unit can result in poor water quality. Our salt service membership adds softener salt every 6 to 8 weeks, and the reverse osmosis plan includes a filter change each year for five years.
