Water Quality in Maplewood
Maplewood is a first-ring suburb on the east side of St. Paul with a mix of 1950s-1970s housing in established neighborhoods and newer infill development. Because Maplewood is on St. Paul Regional Water Services, the water profile differs significantly from suburban-well-source cities.

Common Water Issues We Solve in Maplewood
Most Maplewood homes we visit fall into one of these four buckets. Free in-home test confirms which apply to yours.
Chlorine and Chemical Taste
Maplewood municipal water often carries detectable chlorine taste at the kitchen tap. An under-sink RO or whole-home carbon filter removes it cleanly and improves drinking water quality.
Drinking Water Contaminants
Beyond hardness, Maplewood 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 Maplewood homes are 30+ years old. Original water heaters, softeners, supply lines, and shut-off valves are often due for replacement. Proactive maintenance prevents emergencies.

Is Maplewood water harder or softer than other East Metro cities?
Softer. Maplewood is on Saint Paul Regional Water Services, which runs lime softening at the McCarrons treatment plant. Typical hardness is 6-8 grains per gallon, compared to 14-20 in well-source suburban cities. A softener is still recommended, but the sizing math is different.
What is the most common Maplewood service call?
Mainline backups in established neighborhoods with mature trees, water heater replacements on 10+ year-old units, and softener replacements. The softer source water means dishwasher and laundry damage is less aggressive than in other East Metro cities.
