Common Water Problems

What Could Be In Your Water

City and well water each carry their own issues. These are the problems we see most often in homes — the only way to know yours is a real water test.

Hardness & Limescale

Calcium and magnesium leave scale in pipes and water heaters, spot dishes and shorten appliance life.

Chlorine & Chloramine

City disinfectants keep water safe in the pipes, but leave a chemical taste, odor and dry skin behind.

Lead & Heavy Metals

Older service lines and fixtures can leach lead and other metals — a health risk with no taste or smell.

PFAS / PFOS

"Forever chemicals" from industrial and agricultural sources resist breakdown and need targeted filtration.

Sediment & Iron

Sand, rust and silt cloud water, stain laundry and fixtures, and clog valves and aerators.

Bacteria & Nitrates

Well and rural supplies can carry microorganisms, nitrates or sulfur odor that require disinfection.

Already Have a System?

Service and Maintenance For Any Existing Unit

You don't need a new system to work with us. A softener or reverse osmosis unit is only as good as its last service — media exhausts, membranes foul and settings drift. We inspect, service and maintain what you already own, whoever installed it.

Any Brand, Any Age

We service softeners and filtration systems we didn't install — no matter the brand or how long it's been running.

Annual Tune-Ups

Resin check, valve and control programming, salt dose, leak inspection and a fresh water test each visit.

RO Filter & Membrane Changes

Pre-filters and carbon every 6–12 months, membrane every 2–5 years. Skip them and your RO quietly stops purifying.

Repairs & Upgrades

Failing valves, stuck brine tanks, low pressure or an outdated head — repaired, or upgraded if it's past its life.
