FAQs

How do under-sink water filters work and what contaminants do they remove?

Our under-sink systems route cold tap water through a dedicated purification cartridge before it reaches the faucet. Inside the cartridge, a multi-stage media combination—typically sediment pre-filtration, activated carbon, and in some models a high-capacity reverse-osmosis or ultrafiltration membrane—traps particles down to 0.5 µm and adsorbs chemical pollutants. The result is up to 99 % reduction of chlorine taste and odor, lead, mercury, VOCs, pesticides, micro-plastics, and many more contaminants commonly detected in Spring City’s municipal supply and nearby private wells.

Is my existing plumbing in Spring City compatible with your under-sink filtration systems?

Almost certainly. The filters connect to the standard ⅜-inch cold-water supply line found under most U.S. kitchen sinks, including those installed in Spring City homes built as far back as the 1960s. If your plumbing uses PEX, copper, or braided stainless steel connectors, our quick-connect fittings will attach without modification. Homes with galvanized lines may require a simple adapter, which we stock. During the free in-home consultation, our technician confirms pipe size, water pressure, and clearance to ensure a seamless fit.

What is involved in the installation process and how long does it take?

A certified plumber drills a discrete hole for the purified-water faucet (unless you already have an unused sprayer port), mounts the cartridge housing on the cabinet wall, splices into the cold-water line with a T-valve, and runs a flexible tube to the faucet. Models with a reverse-osmosis membrane also connect a drain saddle to the sink’s tailpiece. Typical installation time is 60–90 minutes, with no need to shut water off to the rest of the house. Your countertop and cabinet remain intact, and we remove all packaging and debris before leaving.

How often do the filter cartridges need to be replaced and how will I know?

For Spring City’s average 250 ppm total dissolved solids and moderate chlorine levels, carbon block cartridges last about 6–12 months (750–1,000 gallons), while RO membranes last 2–3 years. Every system is equipped with a built-in flow meter and color-change indicator that alerts you when throughput reaches the cartridge’s rated capacity. We also send email reminders and offer an optional auto-ship program so replacements arrive at your door on schedule.

Will installing an under-sink filter affect my water pressure or flow rate?

A properly sized under-sink filter causes negligible pressure loss—about 2–5 psi—imperceptible during normal use. Flow at the dedicated purified-water faucet is designed for efficient filling of glasses and cookware (0.75–1.0 gpm). Your main kitchen faucet remains on the original line, so dish-washing and other tasks see zero change in pressure. If your home has unusually low supply pressure (<35 psi), we recommend our high-flow or pump-assisted models to maintain performance.

What certifications do your under-sink filters carry and why are they important?

All systems are independently tested and certified by NSF/ANSI and IAMPO to Standards 42 (aesthetic chlorine reduction), 53 (health-related contaminant reduction such as lead and cysts), and, for reverse-osmosis models, Standard 58. These marks guarantee that the unit meets rigorous safety, structural integrity, and contaminant-reduction claims. Certification also satisfies Spring City building code requirements and may help you qualify for local utility rebates on water-quality improvements.
