If you live in Pomona, Rancho Cucamonga, Ontario, or anywhere in the Inland Empire, you have hard water. Pomona Valley municipal water typically measures 15–20 grains per gallon — well above the 7-grain threshold that the Water Quality Association considers "hard." Here's what that means for your plumbing and what you can do about it.
What Is Hard Water?
Hard water contains high concentrations of dissolved minerals — primarily calcium and magnesium. These minerals are picked up naturally as water flows through limestone and soil before reaching your tap. Hard water is not a health hazard, but it causes significant problems for plumbing, appliances, and fixtures over time.
How Hard Water Damages Your Plumbing
Water Heater Damage
Hard water is the #1 enemy of water heaters. Calcium and magnesium precipitate out when water is heated, forming a thick sediment layer at the bottom of your tank. This sediment insulates the water from the burner, making the heater work harder (higher gas bills), overheating the tank bottom (accelerating corrosion), and reducing effective capacity. In the Pomona Valley, water heaters without regular maintenance often fail 2–3 years earlier than expected.
Pipe Scale Buildup
Mineral deposits accumulate inside pipes over years, gradually narrowing the internal diameter. Galvanized steel pipes (common in pre-1970s homes throughout Pomona) are particularly susceptible — hard water scale combines with pipe corrosion to severely restrict flow. The result: low water pressure throughout the house, reduced flow at fixtures, and eventually, pipe failure.
Fixture Damage
Hard water leaves white, chalky deposits on faucets, showerheads, and toilet components. Aerators clog, showerheads lose pressure, and toilet fill valves fail prematurely. You've probably seen the white buildup on your faucets — that's calcium carbonate, and it's happening inside your pipes too.
Appliance Wear
Dishwashers, washing machines, and ice makers all suffer from hard water. Scale builds up on heating elements and valves, reducing efficiency and shortening appliance life. Hard water also makes soap and detergent less effective — you end up using more product to get the same results.
What You Can Do About Hard Water
Whole-Home Water Softener
A water softener is the most effective solution. It uses ion exchange to remove calcium and magnesium from your water supply before it reaches your pipes, water heater, and fixtures. A properly sized softener pays for itself over time through reduced plumbing repairs, longer appliance life, and lower energy bills. Call us for a free water quality assessment and we'll recommend the right system for your home.
Annual Water Heater Flush
Even with a softener, we recommend flushing your water heater annually to remove accumulated sediment. Without a softener, this maintenance is critical — it can extend your heater's life by 2–3 years and maintain efficiency. Our technicians include a tank flush with every water heater service call.
Anode Rod Replacement
The anode rod is a sacrificial metal rod inside your water heater that attracts corrosive minerals, protecting the tank. In hard-water areas like Pomona, anode rods deplete faster — typically every 3–4 years instead of the standard 5–6. Check it during your annual flush.
Regular Fixture Maintenance
Unscrew and clean your faucet aerators and showerheads every 3–6 months. Soak them in white vinegar to dissolve mineral deposits. This restores water pressure and extends fixture life.
