Cucamonga Valley Water District supplies water to Rancho Cucamonga, and its water quality report is where to find the hardness figure that sets the size of a softener. A plumber can test your tap, recommend a unit and install it. Call the number on this page to be connected with a local plumber in Rancho Cucamonga.
Rancho Cucamonga stretches from Foothill Boulevard, the historic Route 66, up through Alta Loma and Etiwanda toward the foothills. The City lists Cucamonga Valley Water District (CVWD) as its water provider, reachable at (909) 944-6000. This page does not quote a CVWD hardness figure, so the first job is finding your number, either from the district's report or from a test at your own sink. Electric service, which the softener's control valve needs, comes from either Southern California Edison or the city-owned Rancho Cucamonga Municipal Utility depending on the area.
What to do now
- Look up your hardness. Find CVWD's annual water quality report or call the district and ask for the hardness figure.
- Test at the tap. Simple test strips give a rough reading; the plumber can do a more precise test.
- Check your water heater. Note its age and whether it rumbles. If it is near the end of its life, plan to install the softener first.
- Find the main and a drain. Most softeners go in the garage on the main line, close to a laundry standpipe or other drain and a power outlet.
- Decide on outdoor water. Lawns and plants do not need softened water, so plan to keep irrigation and hose bibs on the bypass side.
- Think about drinking water. If taste is a concern, ask about adding carbon or an under-sink reverse osmosis unit at the same visit.

|---|---|
| White crust on faucets and showerheads | Calcium and magnesium deposits |
| Cloudy glasses after the dishwasher | Mineral film from hard water |
| Popping sounds from the water heater | Sediment and scale on the tank bottom |
| Weak shower spray | Scale narrowing showerhead openings |
| Salt piling up in the brine tank of an existing softener | Salt bridge or a failed control valve |
Cost factors
- Unit size, set by hardness and household water use
- Whether the garage has an existing softener loop
- Pipe and drain work needed at the install spot
- Metered versus timed regeneration
- Filtration add-ons
- Removing an old unit
The City of Rancho Cucamonga Building & Safety handles permits through its Online Permit Center; the plumber can confirm whether your installation needs one.
