FAQs
What types of water purification systems do your licensed technicians install for Cosby homeowners?
Our team is trained to size, install, and service a full range of purification technologies, including whole-house carbon filtration for chlorine and pesticides, reverse-osmosis (RO) drinking-water stations, ultraviolet (UV) disinfection for bacteria, point-of-entry sediment filters, and water softeners that remove hardness minerals. We match the equipment to your specific water conditions, plumbing layout, and household usage so you get clean, great-tasting water at every tap.
How do I know which water treatment system is right for my well or municipal water supply in Cosby?
The first step is a comprehensive water analysis. We collect on-site samples and test for pH, hardness, iron, sulfur, tannins, total dissolved solids (TDS), chlorine, and microbiological contaminants. Once we have your lab report, our licensed plumber reviews the results with you, explains any problem areas, and recommends a customized solution that meets Tennessee Department of Environment and Conservation (TDEC) standards. This data-driven approach ensures you purchase only the equipment you need.
Are your plumbers properly licensed and certified to install and service water purification equipment?
Yes. Every technician holds a Tennessee Journeyman or Master Plumbing License, is bonded and insured, and maintains manufacturer certifications for brands such as Pentair, Aqua-Pure, and VIQUA. Our staff completes annual continuing-education courses on backflow prevention, cross-connection control, and advanced water treatment to stay current with state plumbing codes and ANSI/NSF performance standards.
How often will filters, membranes, and UV lamps need to be replaced, and can you handle the maintenance?
Replacement intervals depend on water quality and usage, but most Cosby homeowners schedule: • Sediment and carbon cartridges—every 6-12 months • RO membranes—every 2-3 years • UV lamps—annually • Water-softener resin cleaning—yearly We offer affordable maintenance plans that include scheduled filter changes, system sanitation, performance checks, and emergency service discounts. Package customers receive reminders so your equipment always runs at peak efficiency.
Will installing a water purification system eliminate hard-water scale and protect my plumbing fixtures?
A traditional purification filter removes chemicals, odors, and particles but does not address hardness minerals. If scale buildup is a concern, we integrate a water softener or salt-free conditioner upstream of the purifier. Softening keeps calcium and magnesium from precipitating on heaters, faucets, and appliances, extending their life and improving soap efficiency. Many clients choose a combo system—softener plus RO tap unit—for complete treatment.
What is the typical cost and installation time for a residential water purification system in Cosby?
Pricing varies with water conditions, flow rate, and the number of treatment stages, but most whole-house systems we install fall between $1,200 and $4,500, including professional labor and permit fees. A single-faucet RO station averages $450–$900. Once equipment is on-site, a standard installation takes 3–6 hours and is often completed in one visit. We provide upfront written estimates, financing options, and a workmanship warranty, so there are no surprises.
