City of Garden Grove Water Services
Garden Grove water measures 18 grains per gallon
That is extremely hard — 316 ppm as calcium carbonate, and 1.8× the 10 grain line at which water is officially called hard. City of Garden Grove Water Services publishes the figure in its 2024 water quality report.

What size fits
What size softener fits a home in Garden Grove
Installers all size softeners the same way. Here is what that means for your household — and the math behind it if you want to check our work.
For a 4-person home in Garden Grove
32,000 grainsoftener
At 18 grains, a household your size uses enough water each week that the softener has to remove about 25,200 grains of minerals before it rinses itself clean. A 32,000 grain unit handles that with room to spare.
Right size at 18 grains
How we worked that out
- How much water your household uses200 gal/day4 people × 50 gal
- Minerals removed each day3,600 grains200 gal × 18 gpg
- What builds up in a week25,200 grains3,600 × 7 days
- Unit size32,000 grain
A unit that is too small cannot keep up — scale keeps forming even with a softener installed. This is a starting point, not a specification. Actual sizing depends on your measured tap hardness, iron content, peak flow rate and how the plumbing is laid out — which is what the onsite test establishes.
Where Garden Grove’s water comes from
Predominantly Orange County groundwater at 18 grains, with imported Metropolitan water at 16 grains making up the balance.
At 18 grains per gallon, Garden Grove sits above the countywide typical figure of 13.9 grains. Among the hardest water delivered in Southern California.

What we install in Garden Grove
Same five systems everywhere in the county. Which one you need depends on what you are trying to fix.
Water softenersRemoves the calcium and magnesium that scale your pipes, water heater and fixtures.
The whole-home system. It is the only one of these that actually removes hardness, so it is the one that protects the building.
Reverse osmosis drinking waterA dedicated drinking and cooking tap, filtered down to the dissolved solids a softener leaves behind.
A softener treats the house; reverse osmosis treats the glass you actually drink from. Most households that install one install both.
Whole-home filtration & conditionersCarbon filtration for taste and odour, and salt-free conditioning where a softener is not an option.
Worth knowing before you buy: a conditioner prevents some scale but does not remove hardness. It cannot do most of what a softener does.
Tankless & tank water heatersSupply and installation, and the softener that keeps a tankless unit from scaling shut.
Hard water and tankless heaters are a bad combination. If you are installing one in Orange County, size the softener at the same time.
Commercial & officeCommercial softeners, commercial reverse osmosis, and bottleless office drinking water.
For restaurants, salons, offices and property managers. Bottleless coolers usually replace a delivery contract outright.

In their own words
“I can see why they have so many 5 stars. Got to give credit where credit is due, CCW was amazing. Quick to quote, quick to answer and easy to schedule. They arrived right on the dot and got my water softener system running fast. The guys who came were all honest, professional and friendly. Set up my unit outside and it looked super clean. I shopped around and their pricing was by far the best for the best system (Clack). I already recommended them to my family and now my sister is looking to get a system done by them too. Loving my soft water so far, thanks Tony and team!”
“Tony is very professional and knowledgeable. I spent $98 on an inspection from another technician, but they couldn't figure out why my water softener wasn't working. Another company then quoted me nearly $2,500 to replace the circuit board, resin, and other parts. Tony spent about 45 minutes and fixed everything for just a little over $300. Highly recommended!!!!”
“We had a wonderful experience with Crystal Clear Water. Tony came out and gave us a quote for a water softener and RO system hookup. The quote was detailed, competitive, and included everything we needed to make sure the softener worked properly. When it came time to do the job, the team showed up on time and asked clarifying questions to make sure it was done the way we wanted it. Once everything was all hooked up, they walked me through what was done and how we needed to care for it. I really appreciated how detailed they were and the fact that I received a text when they were on their way that included a picture and the name of the technician that would be arriving.”
Questions from Garden Grove homeowners
Is Orange County water hard?
Almost everywhere, yes. Published figures for most cities land between 11 and 20 grains per gallon, against a threshold of 10 grains at which the water districts themselves call water hard. Tustin publishes the hardest figure in the county at 22 grains and Yorba Linda is not far behind at 20. There are two real exceptions worth knowing: Mesa Water District, which supplies Costa Mesa entirely from local groundwater, publishes 6.6 grains, and Seal Beach reports its own groundwater at 3.9. If you are in either of those places, get the tap tested before you buy anything.

Do I still need a water test if you already show my city’s number?
Yes, and it is free. The published figure is a district-wide average across a year. Your actual tap depends on where you sit in the distribution system, which source was blended in that week, and what your own plumbing has accumulated. The number on this site tells you whether to bother; the test tells you what to install.
What size water softener do I need?
Multiply your water hardness in grains per gallon by roughly 50 gallons per person per day, by the number of people in the house, by a seven-day regeneration cycle, then round up to the next standard grain capacity. A four-person household on 14 grain water needs about 19,600 grains removed per week, which is a 24,000 grain unit. The calculator on this site does this for you using your city’s published hardness.
How much does a water softener cost installed?
It is quoted after a site visit, and we will not publish a number we cannot stand behind. Installed cost depends on the grain capacity your household needs, whether there is an existing loop, where the unit has to go, and whether drain and power are already close. The test and the quote are free and there is no obligation at the end of them.
