Spots on every clean dish
If glassware comes out of the dishwasher covered in white film or rings, that's dissolved calcium, and it's the same scale building up inside your pipes and water heater.

Why Water₂O
Engineered for Your Home.
We measure your GPM, map your peak-hour demand, and engineer a system sized to how your household actually uses water. Backed by a 12-year warranty, a $500 annual maintenance plan, and true 24/7 support.
True 24/7 Support
Call or text any time. Nights, weekends, holidays. You reach the same team that built your system, not a call center. That's support you can actually count on.
Sized to Your Home
We calculate your GPM, count how many showers run at peak hours, and check for high-flow fixtures. Then we engineer a system matched to your actual water usage, not pulled off a shelf.
Custom Installation
Choose your tank color, have it painted to match your home, or bury the system out of sight. Every install is tailored to your space so it looks like it belongs.
Best Price Guarantee
Installation runs $500 to $2,000 depending on your setup. Bring us any written quote and we will match or beat it. Premium engineering at a price that is fair and transparent.
The numbers behind Southern California's water crisis , backed by peer-reviewed research and EWG data.
According to the U.S. Geological Survey (2024), approximately 85% of American homes have hard water. The average household spends over $1,000 per year on bottled water (IBWA, 2024), and hard water costs homeowners up to $800 annually in increased energy bills and appliance damage (U.S. Department of Energy, 2023).

When to Test Your Water
You should schedule a water test if…
Any one of these is a sign your water is working against your home, your appliances, and your family. Most homeowners check more than one box.
Skin feels tight or itchy after showering
Chlorine and hard minerals strip your skin's natural oils. If you moisturize daily and still feel dry, your water is the cause, not your skin.
Hair feels straw-like or color fades fast
Hard water minerals coat the hair shaft, blocking conditioner and locking in chlorine. Salon color and keratin treatments wash out in weeks, not months.
Crusty buildup on faucets and shower glass
If you're scrubbing fixtures every week and the white film keeps coming back, that mineral scale is the visible part of what's happening inside your plumbing.
Water heater is loud, slow, or leaking
Rumbling, popping, or a heater that needs replacing every 6-8 years instead of 12+ is a classic sign of scale collapse. Hard water cuts heater life in half.
Water smells like a pool
That chlorine scent is the same disinfectant used in pools, your lungs and skin absorb it in every hot shower. Chloramine doesn't dissipate with boiling.
Eczema or sensitive skin in the household
Pediatric dermatologists routinely flag hard, chlorinated water as a trigger for childhood eczema flares. A water test should come before another round of creams.
You're buying bottled water every week
If you don't trust what comes out of your tap, you're already paying for water filtration, just the most expensive, least convenient version of it.
