Columbia Basin Plumbing is a family-owned plumbing company that says it has served the Tri-Cities since 2014. Its residential page lists plumbing repairs and maintenance (faucets, running toilets, garbage disposals, hose bibs), tank and tankless water heater repair and installation, water line repair and replacement from the meter to the house, gas line work including BBQ and appliance hookups, water softener installation and service, and plumbing for bathroom and kitchen remodels and custom homes. It also does septic system installation and drain field replacement, but not septic pumping.
The contact page gives the service area as Kennewick, Richland, Pasco, West Richland and surrounding areas. The company says its phone is answered around the clock for scheduling and that most jobs are booked same-day or next-day; it does not advertise 24/7 emergency dispatch. It also does commercial work, including medical gas systems.
