FAQs
What water purification systems do your certified technicians recommend for Kelso’s water quality?
Our technicians typically recommend a two-stage approach for Kelso homes: (1) a whole-house sediment and carbon pre-filter to remove chlorine, dirt, and organic compounds common in Cowlitz County’s municipal supply, and (2) a point-of-use reverse-osmosis (RO) system installed under the kitchen sink for drinking and cooking water. This combo delivers broad contaminant reduction—including lead, pesticides, PFAS, and microplastics—while preserving water pressure and taste. Before making a final recommendation, we always perform an on-site water test to tailor the solution to your exact water chemistry.
Are your plumbing and water purification technicians licensed and certified?
Yes. All field staff hold Washington State plumbing licenses (PL01 or PL02) and have completed manufacturer-approved training for the major purification brands we install (Pentair, A.O. Smith, Water-Right, and Watts). They’re also certified through the Water Quality Association (WQA) as Certified Water Specialists (CWS) or Certified Installers (CI). Copies of licenses and certification cards are available upon request, and our company maintains full general liability and bonding for work performed within Kelso city limits.
How long does a typical water purification installation take in Kelso homes?
Most projects are completed in a single day. A whole-house system with pre-filter and scale inhibitor typically takes 2–3 hours. Adding a reverse-osmosis unit and dedicated faucet usually adds another 2 hours. Complex plumbing configurations—such as homes with finished crawl spaces or older galvanized piping—can extend the job to 6–7 hours. We provide a precise timeline during your free on-site estimate and always schedule installations at times that minimize disruption to your household routine.
What maintenance is required after installation, and do you offer service plans?
Standard maintenance includes changing the whole-house sediment/carbon cartridges every 6–12 months and RO membrane/filter sets every 18–24 months, depending on water usage and quality. Our Kelso Service Plus Plan covers all parts, labor, and annual water testing for a low monthly fee. Members receive priority scheduling, 10% off any additional plumbing repairs, and a lifetime workmanship warranty as long as the plan remains active.
Will a purification system affect my water pressure or flow rate?
Properly sized systems should not cause noticeable pressure drops. Our technicians calculate flow requirements based on fixture count and peak household demand. We select filtration housings and media that can handle 10–15 gallons per minute for most single-family homes in Kelso. After installation, we verify static and dynamic pressure and adjust bypass valves or booster pumps if needed to keep pressure within the recommended 40–80 psi range.
Do you help with local rebates or permits for water treatment installations?
Absolutely. Kelso Public Works and Cowlitz PUD periodically offer rebates for water-saving fixtures and certified filtration upgrades that reduce chlorine byproducts. We stay updated on current incentives, prepare all paperwork, and provide the compliance documentation required for permit closure when a plumbing permit is necessary. Our office staff submits the forms on your behalf so you can claim any rebates or tax credits quickly and hassle-free.
