Glendale Water and Power classifies the city’s supply as very hard — averaging over 12 grains per gallon. If you have lived in Glendale for more than a year you have already met the evidence: white crust on the faucets, spots on every glass out of the dishwasher, and soap that never quite lathers. We are a short drive away in Burbank, we hold a 4.9-star rating across 127 Google reviews, and we have been fixing Glendale hard water for over 20 years.

Why Glendale water is harder than most of LA
Glendale has a hardness problem that is specific to how the city sources its water, and the utility explains it openly.
Roughly 70% of the supply is imported through the Metropolitan Water District, and a large share of that is Colorado River water — which Glendale Water and Power describes as very hard. In wetter years, MWD blends in softer State Water Project water from Northern California before treatment, which brings the number down. In dry years there is little or nothing to blend with, and Glendale receives the Colorado River water close to full strength.
The other ~30% comes from local groundwater wells, and as GWP puts it, Glendale well water is generally harder than the Colorado River water. That well water is treated and blended back into the system.
The practical consequence is the part most homeowners never get told: hardness in Glendale varies by neighborhood and by season, depending on which blend is reaching your street. A reading in Adams Hill is not necessarily a reading in Montrose. This is why we test at your tap instead of quoting from a city average.
| Grains per gallon | Classification |
|---|---|
| Under 4 | Soft |
| 4 – 7 | Moderately hard |
| 7 – 10 | Hard |
| Over 10 | Very hard — Glendale sits here |
Glendale is past the threshold where water is classified “very hard” — and because the blend shifts by street and by season, your own reading can sit well above the city average. That is the case for testing at your tap rather than working from a published number.

What very hard water does to a Glendale home
- Scale in the water heater. Calcium bakes onto the heating surface and insulates it. The heater burns more energy for the same hot shower and dies well before its rated lifespan. Tankless units are the most vulnerable of all.
- Appliance failure. Dishwashers, washing machines, ice makers and coffee equipment fail at the scale line. Manufacturer warranties generally exclude scale damage, so the cost lands on you.
- Spotting you cannot clean away. Those aren’t water marks, they’re mineral deposits left after the water evaporates. No amount of rinse aid fixes the cause.
- Soap that will not work. Hard water binds with soap before it can lather, so you use more detergent and shampoo and get less from it.
- Dry skin, dull hair, stiff towels. The residue that films your shower door does the same thing to skin, hair and fabric.
- Restricted pipes. Over years, scale narrows the interior of your plumbing and drops your water pressure.
What we install in Glendale
Salt-based water softeners
Ion exchange is the only method that actually removes calcium and magnesium, and at Glendale’s hardness level it is what most homeowners genuinely want: real soft water, working soap, no more spotting. Our Praz Signature system delivers 58 gallons per minute with 225,000-grain capacity on a metered valve, so it regenerates on your actual usage rather than a clock — which matters more the harder your water is.
Salt-free conditioners (TAC)
Template Assisted Crystallization neutralizes hardness minerals so they cannot bond to your plumbing, without removing them. No salt, no drain line, no wasted water, almost no maintenance. It protects your equipment but does not produce the soft-water feel or stop spotting. A strong fit for Glendale’s many condos and apartments, HOA-restricted properties, and installs with no drain access.
Whole-house filtration
Hardness is one problem; chlorine, chloramine, taste, odor and sediment are another. A whole-house filter handles the second set. Most Glendale homes we work on get a softener and filter together — we build them as a matched combination system.
Reverse osmosis drinking water
An under-sink reverse osmosis system gives you bottled-quality water straight from the tap for drinking, cooking, coffee and ice — and ends the bottled water bill permanently. We also install alkaline systems.
Commercial water treatment
The restaurants along Brand Boulevard, the offices in the Americana and Glendale Galleria corridor, salons, dental and medical practices, and the light industrial properties in the south of the city all pay for hard water in equipment. Scale is the leading cause of early failure in commercial dishwashers, steamers, espresso machines, ice machines and boilers. Our commercial line runs 78 gallons per minute at 250,000-grain capacity, and we also offer bottleless cooler rentals and commercial reverse osmosis.
Repairs and service for existing systems
You do not need to be buying a new system to call us. We service and repair water softeners in Glendale regardless of who installed them: failed control valves, systems stuck in regeneration, salt bridging in the brine tank, resin that has reached the end of its life, leaking bypasses and units that were undersized for Glendale hardness in the first place. If a system can be economically repaired we will tell you so rather than sell you a replacement.

How it works
- Free water test at your home. We measure your actual hardness at your actual tap. Given how much Glendale varies by neighborhood, this matters more here than almost anywhere else in the county.
- A straight recommendation. Correct system, correct size, honest price — including telling you when the smaller option is enough.
- Professional installation. Typically one visit, clean work, proper bypass and drain, and a walkthrough before we leave.
- Ongoing service. Warranty on parts and labor, bi-monthly checkups, salt delivery, and a team a short drive away when something needs attention.

Frequently asked questions
How hard is the water in Glendale, CA?
Glendale Water and Power classifies the city’s water as very hard, averaging over 12 grains per gallon. Anything above 10 grains per gallon is very hard. Levels vary across Glendale because the city blends imported Colorado River water with local groundwater, and the groundwater is generally harder — so your street may test higher or lower than the city average.
Why is Glendale’s water harder in some years than others?
Most of Glendale’s imported supply is Colorado River water, which is naturally very hard. In wet years the Metropolitan Water District blends it with softer Northern California water before treatment, lowering hardness. In drought years there is little of that softer water available, so Glendale receives harder water.
How much does a water softener cost in Glendale?
It depends on your home’s size, your measured hardness and whether you add filtration or reverse osmosis. We quote a firm price after the free water test rather than a vague range over the phone, and new customers get 10% off.
Do you repair water softeners in Glendale, or only install new ones?
Both. We repair and service systems we did not install — control valves, resin replacement, brine tank issues, leaks and systems that were undersized. If a repair is the sensible answer, that is what we will recommend.
Can I install a water softener in a Glendale condo or apartment?
Often yes, but drain access and space are the constraints, and some HOAs restrict salt-based systems. A salt-free TAC conditioner needs no drain line or brine tank, which makes it the usual answer for these properties. We will confirm what is possible when we come out to test.
How quickly can you get to Glendale?
We are based at 3611 W Pacific Ave, Ste A in Burbank, a short drive away, and we generally schedule Glendale water tests and installations within the same week.
What is the difference between a water softener and a water filter?
A softener removes the calcium and magnesium that cause scale and block soap from lathering. A filter removes chlorine, taste, odor and sediment but leaves hardness untouched. They address different problems, and most Glendale homes need both.
