Truly Clean Drinking Water for Southern California Homes

Does your tap water taste bitter or metallic, leave cloudy ice cubes with white flakes floating in your glass, or have you hauling cases of bottled water home every week? Those are the classic signs of high total dissolved solids making it past the municipal treatment plant and into your kitchen. The Water Heater Company is ready to test your water and install a reverse osmosis system that fixes it at the tap.

Reverse osmosis is the deepest level of residential water treatment we offer. Where a whole-house carbon system handles chlorine, taste, and odor for every fixture, a reverse osmosis system forces water through a semi-permeable membrane and strips out what carbon cannot touch — dissolved solids, heavy metals, fluoride, and the microscopic contaminants responsible for that off taste in your coffee and cloudy film in your ice. It is the right tool when you want bottled-water quality from your own faucet.

Point-of-Use RO Installation

Most homes are best served by a point-of-use reverse osmosis system installed under the kitchen sink, feeding a dedicated drinking-water faucet and, in many cases, the refrigerator's ice maker and water dispenser. We mount the membrane and filter stages cleanly, route the drain line correctly with the required air gap so there is zero risk of cross-contamination from the sink drain, and pressurize the storage tank to the manufacturer's specification so you get a fast, steady fill at the tap.

Why professional installation matters:

• An incorrectly routed drain line wastes water and can violate plumbing code.
• A storage tank at the wrong pressure gives you a trickle instead of a stream.
• Missing air gaps create a real cross-contamination risk from the drain.
• Poorly seated membranes and O-rings cause slow leaks inside your cabinet.

RO Membrane & Filter Service

A reverse osmosis system is only as good as its membrane and pre-filters. The carbon pre-filter protects the membrane from chlorine damage, and once it is exhausted, the membrane degrades fast. We service all major residential RO brands — replacing sediment and carbon stages, sanitizing the system, testing the storage tank air charge, and verifying rejection rates with a dissolved-solids meter so you can see the numbers before and after.

Signs your RO system needs service:

• The dedicated faucet flow has slowed to a dribble.
• Water taste has drifted back toward the tap-water baseline.
• The system runs to drain constantly or you hear it cycling at night.
• It has been more than a year since the last filter change.

System Sizing and Water Quality Diagnostics

We do not guess at what is in your water. Before recommending any equipment we test hardness, chlorine, total dissolved solids, and pH right at your sink. If your dissolved-solids reading is genuinely high, reverse osmosis is the honest answer. If your real problem is hardness scale or chlorine taste, we will tell you that too — a water softener or whole-house filtration system may be the better fit, or the ideal setup may combine them, with RO polishing the drinking water after the softener has done the heavy lifting.
