Water Softener & Filtration Installation in Kensington, MD
Kensington homes get moderately hard water from WSSC Water. We soften it, remove the disinfectant and polish your drinking water for $2,499 installed.
What is in Kensington's water
Kensington is WSSC Water, moderately hard and chlorine-treated. The requests we hear from Kensington are scale on fixtures, dry skin, and better drinking water, plus lead precautions in the Victorian-era homes.
Seasonal changes
None expected for a free-chlorine system, but check the annual report.
Lead and older plumbing
Older neighborhoods in Takoma Park, Silver Spring and Hyattsville have pre-1960 housing. Lead does not come from the treatment plant.
PFAS: Utilities that draw from the Potomac have reported low-level PFAS detections in routine monitoring. EPA finalized limits for PFOA and PFOS in 2024. An under-sink reverse osmosis system certified to NSF/ANSI 58 is the practical fix at the tap you drink from.

WSSC Water is one of the largest utilities in the country and serves most of suburban Maryland. Hardness is moderate and varies by plant, so the most common goals are spot-free glass, softer skin and better-tasting drinking water.

Homes in Kensington
Kensington and Garrett Park are Victorian and early 20th century houses alongside 1950s ranches and Capes. Basements are common but often finished, so we plan the softener around available space and keep drain runs short.
What we usually install here
Whole-home softener with carbon, plus under-sink reverse osmosis. Bethesda and Potomac homes with tankless heaters benefit the most.

Kensington water questions
How hard is the water in Kensington?
Kensington is served by WSSC Water. We expect about 4 to 8 grains per gallon, which is moderately hard. Potomac-plant water tends to run harder than Patuxent-plant water, so the figure depends on which plant serves your neighborhood. Confirm in the WSSC annual report.
Does Kensington tap water contain chloramine?
WSSC Water is understood to use free chlorine rather than chloramine, so a standard carbon stage works and we confirm the current disinfectant before ordering media.
How much does a water softener cost in Kensington?
$1,899 installed for a metered softener with catalytic carbon, or $2,499 with an under-sink reverse osmosis system. That covers equipment, a licensed plumber's installation and startup for a standard install; we quote any extras before booking.
Do you install in Kensington townhomes and condos?
Townhomes, yes, usually with a compact single-tank softener in the utility closet. Condos where the building supply cannot be modified get an under-sink reverse osmosis system, which handles drinking water taste, lead and PFAS without touching shared plumbing.
Is Kensington water safe to drink?
Yes. WSSC Water meets federal and state standards, and we will never claim otherwise. A home system addresses comfort (hardness, disinfectant taste and smell) and, at the kitchen tap, contaminants that enter from home plumbing such as lead.
