FAQs
What is a reverse-osmosis (RO) water purification system and how does it work?
A reverse-osmosis system pushes tap water through a semipermeable membrane that blocks dissolved salts, metals, organic molecules, and microorganisms. The purified water (permeate) is stored in a small pressure tank, while the rejected contaminants are sent to the drain. Pre-filters capture sediment and chlorine before the membrane, and a post-filter polishes the taste before the water reaches your faucet. The result is exceptionally clean, great-tasting drinking water delivered right at your sink.
Why are RO units especially beneficial for homes and businesses in Lookout Mountain?
Many Lookout Mountain properties draw from municipal sources fed by the Tennessee River or from private wells in limestone bedrock. Both supplies can carry elevated levels of hardness minerals, nitrates, agricultural runoff, and occasional boil-water advisories. A properly sized RO unit removes more than 95 % of total dissolved solids, 99 % of lead, and virtually all bacteria and cysts, giving residents peace of mind while eliminating the need for bottled water.
How often do I need to change the filters and membrane in my RO system?
Most systems use three pre-filters (sediment, carbon, and carbon block) that need replacement every 6â12 months, depending on your water quality and consumption. The RO membrane typically lasts 2â5 years, and the post-carbon polishing filter about once a year. Our service plans include annual tests of feed-water total-dissolved-solids (TDS) and membrane performance so we replace components only when necessary, saving you money while ensuring top water quality.
Will an RO unit remove hardness or eliminate the need for a water softener?
An RO membrane removes calcium and magnesium ions, so the drinking water it produces will be soft. However, an under-sink RO treats only the water at that tap. If you have scale buildup in water heaters, dishwashers, or showerheads, you still need a whole-house softener upstream. Many Lookout Mountain homeowners pair a softener with an RO system: the softener protects plumbing and appliances, and the RO provides premium drinking water.
How much water does a reverse-osmosis system waste, and are there ways to reduce it?
Conventional RO units send 3â4 gallons to the drain for every gallon of purified water produced. To minimize waste, we offer high-efficiency membranes that lower the ratio to 1:1, permeate-pump upgrades that use incoming water pressure to reclaim energy, and drain-water reclamation kits that divert reject water to irrigation or toilet tanks. During installation we measure your homeâs water pressure and recommend the most efficient configuration for your needs.
What does professional installation involve, and can I maintain the unit myself?
Installation takes 1â2 hours: our licensed plumber mounts the RO manifold under the sink, taps the cold-water line with a feed valve, installs a dedicated purified-water faucet, connects the drain saddle, and pressure-tests the system. We also sanitize the storage tank and record baseline TDS readings. Homeowners can perform simple filter changes with a supplied wrench, but annual service by our technicians includes membrane integrity testing, tank-pressure adjustment, and leak inspectionâimportant steps to keep your warranty valid and your water safe.
