FAQs
What is a reverse-osmosis (RO) unit and how does it purify my Cosby home’s water?
A reverse-osmosis unit forces tap water through a semi-permeable membrane that has microscopic pores about 0.0001 micron in diameter. Dissolved salts, chlorine by-products, lead, nitrates, PFAS, and many other contaminants are rejected and flushed to drain, while only purified water molecules pass through. The result is clean, great-tasting water that is up to 99 % free of dissolved impurities commonly found in Cosby’s municipal and well supplies.
Which contaminants will the RO system remove from Cosby water, and are any minerals left behind?
Our systems are NSF-certified to reduce lead, arsenic, chromium-6, nitrates, fluoride, chlorine/chloramine, VOCs, microplastics, pharmaceuticals, and up to 97 % of total dissolved solids. Beneficial calcium and magnesium are mostly removed as well, but an optional remineralization filter can be added to reintroduce healthy minerals for taste and pH balance.
Will installing an RO unit decrease my water pressure or increase my utility bill?
Typical under-sink RO units produce 50–100 gallons per day and operate at 40–80 psi, so household pressure remains unaffected. Purified water is stored in a 2–4 gallon pressurized tank that delivers water instantly to its own faucet. While some wastewater is generated during the purification process, the extra water cost for an average Cosby family is usually less than $2–$4 per month.
How often do I need to change filters and service the membrane?
Pre-filters (sediment and carbon) should be replaced every 6–12 months depending on local water quality and usage. The RO membrane typically lasts 2–3 years, and the post-carbon “polishing” filter is changed annually. Our Cosby service team offers affordable maintenance plans that include annual performance testing and automatic filter reminders.
What is involved in installation and how long does it take?
Most residential installations are completed in 1–2 hours. We mount the RO module and tank in the cabinet under your kitchen sink, connect to the cold-water line via a feed valve, install a dedicated drinking-water faucet on the sink or countertop, and run a small drain line to your sink’s trap. No major plumbing modifications are needed, and our licensed Cosby technicians leave the area clean and fully tested before they leave.
Do your RO systems come with warranties and local support?
Yes. All units include a 1-year parts-and-labor warranty and a 3- to 5-year membrane warranty, depending on the model. We are based right here in Cosby, so if you ever experience a drop in pressure, unusual taste, or a leak, a certified technician can typically be on-site within 24 hours. Telephone support and reminder emails for filter changes are free for the lifetime of the system.
