FAQs
What types of contaminants will an under-sink purification system remove from Greenback’s municipal water supply?
Our recommended multi-stage systems target the most common local impurities, including chlorine and chloramine (which affect taste and odor), dissolved heavy metals such as lead and mercury, volatile organic compounds (VOCs) from agricultural runoff, and common microbiological threats (cysts, bacteria, and viruses) that can enter through aging pipes. If you choose a reverse-osmosis (RO) model, it will also reduce dissolved salts, fluoride, and nitrates to below EPA-approved levels, giving you bottle-quality water straight from the tap.
Which purification technology is best—activated carbon, ultrafiltration, or reverse osmosis—and what do you install?
Each technology serves a slightly different purpose: • Activated carbon blocks excel at removing chlorine, chloramine, pesticides, and unpleasant tastes or odors. • Ultrafiltration membranes stop particles, cysts, and most bacteria while keeping beneficial minerals intact. • Reverse osmosis forces water through a semi-permeable membrane that filters out up to 99% of dissolved solids, heavy metals, and fluoride, making it the gold standard for purity. We offer stand-alone carbon or ultrafiltration systems for households that primarily want taste and odor improvement, and high-capacity RO systems for those seeking maximum contaminant removal. Our Greenback technicians can test your water and recommend the right option for your budget and quality goals.
How often will I need to change filters, and are replacements readily available in Greenback?
Filter life depends on local water quality and usage, but most households should plan to replace: • Sediment pre-filters: every 6–12 months • Carbon filters: every 6–12 months • RO membranes: every 24–36 months • Post-carbon polishing filters: every 12 months We stock all replacement cartridges and membranes locally at our Greenback warehouse, so you can pick them up same-day or schedule a technician to perform the change for you. You’ll also receive email or text reminders when service is due.
Will installation damage my countertop or require major plumbing changes?
No. Our under-sink units are designed for minimal disruption. We mount the compact system in the cabinet, tie into the cold-water line with a corrosion-proof feed valve, and route purified water to a dedicated drinking faucet that sits beside your existing tap. For most countertops, we drill a 7⁄16" hole; the process is quick, clean, and fully reversible if you remodel later. Granite, quartz, and solid surfaces are handled with diamond-tipped bits and dust control to protect your kitchen.
Is the purified water safe for cooking, baby formula, and refrigerator ice makers?
Absolutely. Purified water from our systems meets or exceeds NSF/ANSI standards for potable water. Using it for cooking preserves natural flavors and reduces scale build-up in kettles and coffee makers. Parents often choose RO water for baby formula because it minimizes exposure to fluoride and nitrate spikes occasionally seen in municipal lines. We can also run a purified line to your fridge or ice maker so every cube is crystal-clear and free of off-tastes.
What ongoing maintenance or service plans do you offer, and how much do they cost?
You have two options: 1. DIY: Purchase cartridges from us (sediment $12, carbon $28, RO membrane $65) and follow our step-by-step video guide—no special tools required. 2. Full-Service Plan: For $129 per year, a certified Greenback technician will visit annually to replace all filters, sanitize the housing, pressure-test the membrane, and check for leaks. RO membrane swaps, if needed, are billed at cost with no additional labor fee. The plan also gives you priority scheduling and a 10% discount on any future upgrades or repairs.
