What Coronado water projects actually look like
Coronado is an island city where salt air comes from every direction and the water supply delivers the same hard, chloraminated municipal blend as the rest of San Diego. For homeowners in a city where homes are older, investment-grade, or both, protecting the plumbing infrastructure from hard water damage is a practical concern. Scale builds in supply lines, water heaters fail before they should, and glass surfaces in older bathrooms take on a permanent cloudy appearance when nothing treats the water coming in.
Filter Pros installs whole-home water treatment systems using stainless steel tanks specifically because Coronado's environment is one of the most aggressive in the county. Fiberglass-and-liner equipment corrodes faster in this salt-air exposure, and the liner degrades with hard, chloraminated water. Stainless eliminates both problems. The free in-home water test is the starting point, and older Coronado homes sometimes reveal additional concerns (pipe material, legacy plumbing) that the conversation around water quality surfaces.
What does Coronado water need?
Coastal San Diego homes run on very hard imported water, around 17 to 20 grains per gallon, disinfected with chloramine. Salt air also corrodes standard equipment housings, so the tank material matters. We install medical-grade stainless steel tanks that don't rust or break down, paired with catalytic carbon for the chloramine and salt-free conditioning that leaves no sodium in your water.
Working details for Coronado water systems
The Village historic district has a high concentration of older homes with original or partly original plumbing. Hard, chloraminated water is harder on older copper and galvanized steel supply lines than on newer PEX or CPVC. A whole-home conditioner on the main line reduces scale buildup throughout the distribution system and extends the useful life of the plumbing. Coronado Cays and Coronado Shores have newer construction but the same supply, and the scale and chloramine complaints are identical. The free in-home test is the right first step regardless of home age.

What do Coronado homeowners ask about their water?
Does Coronado have hard water?
Yes. Coronado draws from the same San Diego municipal supply as the mainland, and hardness levels typically run 17-20+ grains per gallon. That's in the very hard range. Scale from that water builds on fixtures, glass, and the inside of supply lines and water heaters throughout the home. The free in-home water test confirms the exact level at your tap.
Is chloramine in Coronado tap water and does it matter?
Yes, San Diego water utilities disinfect with chloramine, and Coronado water carries it. Chloramine produces a chemical taste and smell that many people notice. Standard carbon filters don't fully remove it. Catalytic carbon, which Filter Pros uses, does. If you're sensitive to the taste or smell of tap water in Coronado, that's the likely source.
Will a water conditioner help older Coronado Village homes with legacy plumbing?
Yes. Hard water is harder on older copper and galvanized steel supply lines than on newer materials. Scale builds up inside the pipes, narrowing the diameter over time and increasing pressure. A whole-home conditioner on the main line reduces that scale formation throughout the system. It won't reverse existing buildup, but it stops the accumulation from continuing and protects fixtures and appliances from further damage.
Why does Filter Pros use stainless steel tanks on Coronado installs?
Coronado is surrounded by salt water on both sides, and salt-air exposure is aggressive on any equipment that isn't built for it. Fiberglass tanks with plastic liners corrode from the outside and degrade from the inside with chloraminated hard water. Stainless steel tanks don't corrode and don't have a liner to break down. For a home on an island, the durability difference is real.
