Extremely Hard — advanced softener required
Outside the documented East Metro PFAS plume. Plymouth still sits in the extremely hard water zone at 17 gpg, which damages every home daily without softening.
Primary water source

Common Water Issues We Solve in Plymouth
Most Plymouth homes we visit fall into one of these four buckets. Free in-home test confirms which apply to yours.
Iron Staining and Discoloration
Many Plymouth wells show elevated iron, causing orange staining on fixtures, laundry, and tubs. We diagnose ferrous vs. ferric iron on-site and install the right specialty filter.
Drinking Water Contaminants
Beyond hardness, Plymouth tap water can carry trace dissolved metals, sediment, and chlorination byproducts. Under-sink reverse osmosis delivers cleaner drinking and cooking water than most bottled.
Aging In-Home Plumbing
Many Plymouth homes are 30+ years old. Original water heaters, softeners, supply lines, and shut-off valves are often due for replacement. Proactive maintenance prevents emergencies.
