Reverse Osmosis Systems for Wells in Western NY & NW PA
Reverse osmosis is the treatment of choice for Chautauqua County well owners dealing with elevated nitrates, arsenic, or dissolved solids — contaminants that no standard iron filter or water softener can touch. The bedrock geology of Western NY, particularly the shale formations running through southern Chautauqua County into Warren County, PA, concentrates these compounds in deeper wells drilled below the water table. Spring agricultural activity around Mayville and Westfield also spikes nitrate levels in shallower private wells annually. McCandless installs point-of-use under-sink RO units for drinking water as well as whole-house RO systems for households where total dissolved solids (TDS) affect appliances and water heaters. Every RO recommendation starts with a full water test — we don’t size a membrane before we know what it’s rejecting.

Frequently Asked Questions
Why do I need a reverse osmosis system if I already have a well?
Well water can contain sediment, minerals, and bacteria. A reverse osmosis system adds extra protection, filtering out contaminants for cleaner, safer, and better-tasting water.
How much does a reverse osmosis system cost installed in Jamestown, NY?
A quality under-sink RO system runs $400–$900 installed in the Jamestown area; whole-house RO systems for high-TDS or high-arsenic wells range $2,500–$6,000 depending on flow rate and pre-treatment needs. Your water test results determine which configuration is appropriate.
What contaminants can a reverse osmosis system remove from my well water?
Reverse osmosis removes lead, chlorine, nitrates, bacteria, chemicals, and sediment — improving water quality, taste, and clarity.
Will a reverse osmosis system work with my existing well pressure?
Most RO systems require minimum inlet pressure of 40–60 PSI to produce adequate flow. Chautauqua County wells with older submersible pumps or pressure tanks set below 40 PSI may need a booster pump added to the RO system. We check your pressure during the water test appointment before recommending equipment.
How often does a reverse osmosis system require maintenance?
Filters typically need replacing every 6–12 months, with annual system checks. We offer professional maintenance to keep your system running smoothly.
How much water does an RO system waste?
Standard RO systems waste 3–4 gallons per gallon of purified water produced. High-efficiency models available today bring that ratio down to 1:1. For households on limited-yield wells — a common issue in the bedrock formations south of Jamestown — we specifically recommend high-efficiency units to protect well recovery.
Does RO remove iron and hardness from Western NY well water?
RO membranes do reduce dissolved iron and hardness, but high iron levels (above 0.3 ppm) foul the membrane quickly and shorten its life. For well water with both high iron and nitrate concerns, we typically install an iron pre-filter before the RO unit to protect the membrane and extend service intervals.
How often do RO filters and membranes need replacement in this area?
Pre-filters (sediment and carbon stages) should be replaced every 6–12 months; the RO membrane every 2–3 years under normal Chautauqua County water conditions. High-nitrate or high-TDS water will shorten membrane life. McCandless includes a water retest with every membrane replacement to confirm the system is still performing.
Can McCandless Well Drilling and Services, Inc. install a reverse osmosis system with my existing well setup?
Absolutely! We specialize in integrating reverse osmosis systems with well water setups, ensuring optimal performance and water purity.
