What the City report says about your water
In its 2023 Consumer Confidence Report, the City Water Division says the tap comes from deep local groundwater wells. Hardness averaged 174.4 mg/L and ranged from 121 to 212. Dividing by 17.1 gives roughly 10.2 grains per gallon.
Your own tap may sit at either end of that range, or outside it. Some addresses belong to Pico Water District instead, and the City's provider lookup page shows which utility bills you. Check that before you buy anything.
Where Pico Rivera sits on the hardness scale
Cal Water publishes a simple scale in its water reports. We use it as a plain reference.
| Category | Hardness (ppm or mg/L) | Where Pico Rivera falls |
|---|---|---|
| Soft | Under 75 | Below the city's lowest reading |
| Moderately hard | 75 to 150 | Lower end of the city range sits near here |
| Hard | 150 to 300 | The 174.4 average lands here |
| Very hard | 300 and above | Above every reading in the City report |
The scale comes from the Cal Water Commerce 2025 report. The Pico Rivera numbers come from the City's 2023 report.
Test your tap, then decide
A report gives an average. A cheap test strip or a lab test tells you what your house gets. Test before you buy so you size equipment to your water, not to a brochure.
Read your utility's annual report and ask the utility if you have questions about the water itself. We stay on the plumbing side. Bring your results and call {phone} if you want to talk through options.

Two towns, two very different reports
Hardness changes from town to town. These two nearby reports show how far.
Norwalk
The Golden State Water Norwalk system report lists hardness from 137 to 505 mg/L, averaging 310 mg/L, or about 18 grains per gallon. That is in the very hard category on Cal Water's scale.
Commerce
The Cal Water City of Commerce report shows groundwater hardness of 140 to 155 ppm, averaging 146 ppm. That is moderately hard.
Why it matters to you
A softener sized for Norwalk would be oversized in Commerce. Equipment should follow your tap, not your zip code.
If you live or work near Norwalk, we help there too, but test your tap anyway.
Softener, filter, or both
A softener removes hardness minerals through ion exchange. A filter targets other things such as chlorine taste or sediment. They solve different problems, and many homes want only one.
Cal Water's report says hard water may build up in pipes or water heaters. If that worries you, see Tankless Water Heater for how buildup affects a heat exchanger. We make no health claims about any water treatment.
The salt caveat
Cal Water's report notes that some softeners add salt that causes problems at wastewater treatment plants. It also notes they can raise sodium for people on low-sodium diets.
Ask about those trade-offs before you buy, and ask your utility if local rules affect softener discharge. We will not guess at rules we have not read.
What affects the cost of a treatment system
The price is clear before work starts. Five things shape it.
If your conditioner stops working
A softener or conditioner that stopped softening is a common service call. We work through it in this order.
- 1
Check the basics
We confirm power, bypass position and salt level.
- 2
Look at the brine tank
A salt bridge or sludge can stop regeneration.
- 3
Test the output
A hardness test before and after tells us if the unit is working.
- 4
Check valves and drain
Stuck valves and clogged drain lines are common causes.
- 5
Repair or replace
We tell you whether a repair makes sense or a new unit is the better call.
Questions to ask any installer
Use these with us or anyone else.
- What hardness number are you sizing to, and where did it come from?
- Where does the drain line go, and how is it protected?
- Will the unit have a bypass valve?
- What does the salt and maintenance schedule look like?
- What happens to water for the outdoor taps and the water heater?
Treatment equipment ties into your plumbing, so also read Plumbing Installation for how we plan new connections.
Standards and sources behind this page
Hardness figures come from the City of Pico Rivera 2023 water quality report and the scale Cal Water publishes.
Questions we hear most
The City's 2023 report lists an average of 174.4 mg/L, about 10.2 grains per gallon. That is hard on Cal Water's scale. Test your tap, since your address may differ.
Not always. A softener helps with mineral buildup, but it adds salt and a drain connection. Test first and weigh the trade-offs.
Use the City's provider lookup page and type in your address. The map shades City service green and Pico Water District red.
Yes. We check power, bypass, brine tank, valves and drain, then tell you if repair is worth it. Call us with the brand and symptoms.
Cal Water notes some add salt that causes problems at wastewater plants and raises sodium for people on low-sodium diets. Ask about those trade-offs.
The Golden State Water Norwalk system report averages 310 mg/L, higher than Pico Rivera's 174.4. Each tap is different, so test yours.
