Alcorn Pump & Water Filtration is a family-owned well pump and water filtration company serving Enumclaw, in King County, and the surrounding communities. It says its team members are certified electricians and plumbers, and it works on residential, multi-dwelling, farm, irrigation and commercial water systems.

Pumps and water systems. The company installs, repairs and maintains submersible well pumps, submersible and line-shaft turbines, solar pumps, booster and jet pumps and pressure tanks. Its electrical work covers motor controls, control boxes, VFDs and generator transfer switches, and it does pump house plumbing, yard hydrants, and water reservoir and storage systems, including cleaning and inspection. It also sets up temporary pumps for new construction and offers yearly maintenance.

Well rehabilitation. For low-producing or fouled wells it offers brushing and bailing to remove debris, sand and gravel, chemical treatment with NSF-certified acids, jetting and air-lifting, and well shock disinfection with NSF-certified chlorine.

Testing and inspections. It offers pump flow tests, well production (drawdown and recovery) tests of up to three hours, well camera scoping, and water testing for bacteria, arsenic, nitrate, nitrite, PFAS, fluoride, uranium and more. Its well inspections for buyers and sellers review and test each component of the water system and document the findings.

Filtration. It custom-designs filtration for well, community and city water, including treatment for arsenic, bacteria and nitrate, which it describes as common around Enumclaw.

Emergencies. It runs a 24-hour line for out-of-water emergencies. L&I lists electrical and plumbing contractor registrations with the pump and irrigation specialty.
