FAQs
How does an under-sink reverse-osmosis (RO) system work?
An RO system pushes tap water through a semi-permeable membrane and a series of pre- and post-filters. The membrane blocks dissolved solids, heavy metals, and many other contaminants, while the filters capture sediment, chlorine, and odors. The purified water is stored in a small pressure tank under the sink and is delivered to a dedicated faucet on demand. A drain line carries the rejected impurities away.
What contaminants will an RO system remove from Apison’s tap or well water?
Properly maintained RO systems typically reduce 95–99% of total dissolved solids (TDS), including lead, arsenic, chromium, fluoride, nitrates, and many industrial/agricultural chemicals. The carbon stages also remove chlorine, chloramine, volatile organic compounds (VOCs), and many pesticides that can be found in some Hamilton County water sources or private wells around Apison.
How often should I change the filters and membrane?
Most under-sink RO units use three replaceable pre-filters, the RO membrane, and a final polishing filter. In Apison’s moderate-to-high sediment water, pre-filters should be replaced every 6–12 months, the RO membrane every 24–36 months, and the post-carbon filter yearly. Checking TDS levels with a handheld meter every few months helps verify when service is truly needed.
Can I install an RO system myself, or should I hire a professional plumber in Apison?
Many DIY-friendly kits come with color-coded tubing and detailed instructions, and homeowners who are comfortable drilling a countertop hole for the faucet and tapping into a cold-water line can install them in 2–3 hours. However, if you’re unsure about local plumbing codes, have granite countertops, or use a private well that needs pre-treatment, hiring a licensed Apison plumber ensures leak-free connections, proper drain-saddle placement, and warranty protection.
Will an RO system waste a lot of water?
All RO units produce some wastewater to flush away contaminants. Modern 1:1 or 2:1 systems discharge 1–2 gallons for every gallon of purified water; older designs could waste 4 gallons. You can route the reject line to a garden barrel or utility sink for reuse. If you’re on a private well, adding a permeate pump increases efficiency and reduces water sent to the septic system.
Does reverse osmosis water affect taste, minerals, and water pressure?
RO water tastes crisp because it has very low mineral content and no chlorine. Essential minerals lost in the process are small enough to be replaced through diet, but optional remineralization cartridges can add calcium and magnesium back for flavor. Pressure at the RO faucet is slightly lower than your home’s main pressure but sufficient for filling pots and bottles; a full storage tank typically delivers 30–40 psi.
