FAQs
What contaminants do your under-sink filters remove from Etowah’s water supply?
Our multi-stage systems target the most common issues found in Etowah’s municipal and private-well water, including chlorine taste and odor, sand and silt, rust, lead, mercury, VOCs, cysts (Giardia & Cryptosporidium), agricultural run-off chemicals such as atrazine, and emerging contaminants like PFOS/PFOA. Each unit is certified to NSF/ANSI standards 42, 53, and 401, so you can be confident the water coming out of your dedicated faucet is cleaner, clearer, and better-tasting.
How much room do I need under the sink for a typical installation?
Most of our systems require a footprint of roughly 12 in. W × 5 in. D, with 16–18 in. of vertical clearance to allow for cartridge changes. If space is tight—common in historic Etowah homes—we stock slimline and horizontal-mount models that fit in as little as 10 in. W × 4 in. D. During the free on-site consultation, our plumber measures your cabinet, disposal, and existing plumbing to recommend the best unit and layout.
How often do the filter cartridges need to be replaced and what will it cost?
For an average family of four in Etowah, prefilter and carbon stages last 6–9 months, while specialty membranes (lead or PFAS reduction) last 12 months. Light-use households may see up to a year on all stages. Replacement sets range from $45 to $110, depending on model. We notify you when you’re due, and our flat-rate cartridge swap—including a quick leak check—is $39, or you can DIY using the twist-lock heads and included wrench.
Can I install an under-sink filter in a rental property, and will it meet local plumbing codes?
Yes. Under-sink filters are classified as point-of-use (POU) devices and are legal in rental units throughout McMinn County, provided they are installed with a dedicated shut-off valve and do not alter the building’s main supply lines. We use code-approved quick-connect fittings and provide your landlord with a reversible installation letter stating that the unit can be removed without damage when you move out.
Will the filter affect my water pressure or flow rate?
Our systems deliver 0.75–1.0 gpm at the dedicated drinking-water faucet—plenty for filling pots or coffee makers—while leaving your main kitchen faucet’s pressure unchanged. We size the filter media and tubing to match Etowah’s typical street pressure (45–70 psi). A built-in bypass ensures that if cartridges ever clog, the faucet will trickle rather than shut off completely, giving you time to schedule service.
Do you offer maintenance plans and emergency service in Etowah and surrounding areas?
Absolutely. We cover all of Etowah plus Englewood, Athens, Riceville, and Calhoun. Our annual maintenance plan includes cartridge replacement, a pressure test, sanitizing the filter housings, and a 10-point plumbing inspection for $99/year. Members also receive 24/7 emergency leak response with a target arrival of 2 hours or less and 15 % off any additional plumbing repairs.
