Water Softener & Filtration Installation in Olney, MD
Olney 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 Olney's water
Public-water Olney is on WSSC, moderately hard with free chlorine. Well homes around Brookeville and Ashton commonly show iron staining and hardness that need a different system entirely, which is why we test before we quote.
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.

Homes north and east of Olney toward Brookeville and Sandy Spring are frequently on private wells.

- Potomac River (Potomac plant) and the Patuxent reservoirs (Patuxent plant)
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.

Olney water questions
How hard is the water in Olney?
Olney 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 Olney 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 Olney?
$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 Olney 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 Olney 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.
