FAQs
What is reverse-osmosis (RO) water purification and how does it work in a household plumbing system?
Reverse-osmosis is a filtration process that forces water through a semi-permeable membrane with microscopic pores (≈0.0001 micron). In a typical Harriman home installation, city or well water enters a pre-filter stage (sediment and carbon) to remove larger particles and chlorine. The water is then pushed across the RO membrane, which blocks up to 99% of dissolved salts, lead, arsenic, nitrates, PFAS, and many other contaminants. Purified water is stored in a pressurized tank and delivered to a dedicated faucet or refrigerator line, while the concentrated waste stream (brine) is routed to the drain.
Why is reverse-osmosis recommended for Harriman residents specifically?
Tests of Harriman’s municipal and private well supplies show moderately hard water with detectable levels of chlorine by-products, nitrates in some rural wells, and occasional traces of lead from older service lines. RO addresses all of these at once, giving you bottle-quality water on tap. It also removes the mineral hardness that causes scaling in kettles, coffee makers, and ice machines, so you protect appliances while improving taste.
Where is an RO system installed and will it affect my existing kitchen plumbing?
Most residential units fit neatly under the kitchen sink. Our technicians connect the system to the cold-water line with a feed valve, install a small (¼-inch) drain saddle to the sink’s waste line, and mount a dedicated drinking-water faucet on the countertop. If counter space is limited, we can run purified water to your fridge dispenser instead. The installation is non-invasive: no major pipe rerouting, and the standard sink faucet remains untouched.
How often do filters and the RO membrane need replacement?
Pre-filters: every 6–12 months, depending on Harriman’s water quality and household usage. Carbon post-filter: every 12 months. RO membrane: 2–4 years on city water; 2–3 years on high-TDS well water. All replacements are quick twist-off cartridges that homeowners can change themselves, or you can enroll in our annual maintenance program, which includes water-quality testing and sanitizing.
What amount of water does an RO system waste, and is that a concern during Harriman’s summer drought advisories?
Modern 1:1 or 2:1 recovery-ratio systems produce one gallon of purified water for every one to two gallons sent to drain—about the same usage as a single toilet flush per day for an average family. If water conservation is critical, we offer zero-waste kits that redirect the brine to your hot-water line or to a rain barrel for non-potable uses like plant watering.
How much does a complete RO installation cost and are there financing or rebate options?
A quality 5-stage unit with professional installation in Harriman typically ranges from $525 to $725, including the faucet, storage tank, and first set of filters. Annual filter costs average $70–$90. We partner with local utilities that occasionally offer water-quality improvement rebates (up to $100) and we provide 0% financing for 6 months on approved credit. All systems come with a 5-year parts warranty and a 1-year labor guarantee.
