Plumbing service in Rancho Cucamonga
Rancho Cucamonga became a city in 1977 when Alta Loma, Cucamonga and Etiwanda joined together.

We're veteran- and family-owned, based on Third Street in Riverside, about 19 road miles from Rancho Cucamonga City Hall.
Homes from the boom years
Rancho Cucamonga's median home was built in 1988, according to Census data. More than a quarter of its homes went up in the 1980s, and about 30% in 2000 or later. Homes from those years are into a predictable round of repairs:
- Water heaters. Original and first-replacement tank heaters wearing out, and plenty of homeowners switching to tankless. See water heater repair.
- Valves, supply lines and fixtures reaching the end of their life.
- Slab and hidden leaks. A warm spot in the floor or a climbing water bill. See leak detection.
Rancho Cucamonga's online permit center lists water heater and tankless water heater permits as no-plan-check permits that can be issued online.
Rancho Cucamonga's water
Cucamonga Valley Water District supplies water and sewer service. Its 2025 water quality report shows an average hardness of 125.5 mg/L, with a range of 109 to 142. The supply is a mix of imported water, groundwater and canyon water. That's hard water, enough to scale tankless units and fixtures over time. See water treatment.
The district is replacing about 3,800 feet of 12-inch waterline under Baseline Road with federal funding announced in February 2026. The water line between the meter and your house is yours. If it leaks, see water line repair & replacement.
