FAQs
What types of under-sink water purification systems do you install in Old Fort?
We install a full range of systems, including single-stage carbon filters for taste and odor removal, multi-stage reverse osmosis (RO) units for comprehensive contaminant reduction, and combination systems that integrate sediment, carbon, and RO membranes. We can specify models certified to NSF/ANSI standards and matched to Old Fort’s municipal or well-water chemistry.
How do I know which under-sink unit is best for my home’s water quality?
The first step is a professional water test. We analyze for chlorine, hardness, lead, iron, PFAS, and microbiological contaminants common in McDowell County. Once we have results, we recommend a system sized for your daily usage, cabinet space, and target contaminants. Our plumber will walk you through filter life, flow rate, and maintenance costs so you can make an informed decision.
Will an under-sink purifier reduce water pressure at my kitchen faucet?
Most modern systems include a dedicated purified-water faucet, so the main kitchen faucet pressure stays the same. For RO units, the purified stream flows at a slightly lower rate (about 0.5–0.8 gpm) due to fine filtration. We install pressurized storage tanks and 3⁄8-inch tubing to optimize flow and minimize waiting time when filling pitchers or pots.
How often do filters and membranes need to be replaced?
• Sediment and carbon pre-filters: every 6–12 months, depending on usage and sediment load. • RO membranes: every 2–3 years, provided chlorine is removed upstream. • Post-carbon polishing filters: every 12 months. We label the system with service dates and send email reminders. Our Old Fort service team offers annual maintenance plans that bundle filter changes, leak checks, and sanitizing.
Can I install the under-sink unit myself?
Some homeowners with plumbing experience can handle a basic carbon filter install, but RO systems require drilling for a separate faucet, adding a drain saddle, potential icemaker hookups, and ensuring watertight PEX or compression fittings. Hiring a licensed Old Fort plumber protects your cabinetry from leaks, maintains manufacturer warranties, and ensures the system meets North Carolina plumbing code.
What is the total cost of ownership for an under-sink RO system?
Initial installed cost ranges from $425 to $850, depending on capacity and faucet style. Annual filter replacements average $80–$120, and membrane replacement every 2–3 years costs about $90. Over five years, total ownership is typically $800–$1,250—equivalent to 5–10¢ per gallon, far less than bottled water and with a much smaller environmental footprint.
