The City of Chino Hills supplies a blend of imported State Water Project water and groundwater from city, Monte Vista Water District and desalter wells, disinfected with chloramine. A softener handles the hardness minerals; the City's annual water quality report lists the hardness figure. Call the number on this page to be connected with a local plumber in Chino Hills.

How the call works
You are connected with an independent plumber serving Chino Hills. Be ready to describe what is bothering you, such as spotting, crusty fixtures or a water heater that has started to rumble, plus how many people live in the home and where the main water line enters. Most plumbers test a sample at your tap so the unit is sized to your water, not a guess.
A small number of Chino Hills properties are sewer-only accounts with the City and get water from a separate agency. If that is you, mention it, because your hardness figure will come from that agency's report, not the City's.
Cost drivers
- Hardness and household water use, which set tank and resin size
- Main line location, often a garage wall or exterior side yard
- Distance to a drain and outlet
- Whether you add catalytic carbon for chloramine
- Bypass plumbing for landscape irrigation
- Salt or potassium over time
Local water conditions
Chino Hills water is a mix. Imported State Water Project water from Metropolitan, treated and delivered through the Water Facilities Authority and Monte Vista Water District, is blended with groundwater from City wells, Monte Vista wells and Chino Basin Desalter Authority wells. Recycled water from the Inland Empire Utilities Agency goes to irrigation, not to homes. The City's Consumer Confidence Report lists hardness, and this page does not quote a figure, so check the report or test at your tap.
The City's report lists chloramine as the disinfectant. Softening leaves chloramine in the water, so if taste is part of your complaint, pair the softener with carbon. The City's service line inventory found no lead service lines in its area. Plumbing permit items such as water heaters and water supply line work are listed on the City's Building Services fee schedule; the plumber can confirm whether a softener installation needs a permit.
For a water or sewer emergency after 4:45 p.m. or on weekends, the City lists (909) 364-2860.
