Division One LLC.

The state insures Division One's crew under its plumbing and sewer-pipe-cleaning class, which lines up with what the business advertises: drain cleaning, hydro-jetting, camera inspection, sewer line cleaning and repair, leak detection, burst pipe and sump pump repair. Water heaters are a large share of the work, from repair and maintenance to replacement and tankless installation. County permits from 2024 through 2026 cover residential plumbing and residential mechanical jobs. The state lists David Harrison as a principal since 2021, and the crew falls in the four-to-six band. Division One says it carries warranties on its work and offers payment plans. The service list on the company site reaches well past the city: Spokane Valley, Liberty Lake, Greenacres, Veradale, Otis Orchards and Newman Lake to the east, and Airway Heights, Nine Mile Falls, Colbert and Mead to the west and north. That reach suits a homeowner outside city limits who wants a crew that already drives those roads. It also suits urgent calls, since the shop is built around fast service work rather than long remodel schedules. Spokane's housing stock shapes plumbing work more than most people expect. Older homes on the South Hill and in neighborhoods near downtown can still have galvanized supply lines and clay or cast-iron sewer laterals, where roots and corrosion cause the backups that send people looking for a drain crew. A camera inspection before digging tells you whether a line needs cleaning or replacing. Newer houses in the Valley and up north mostly run PEX and PVC, where water heater swaps and fixture changes are the common jobs. On a rural lot with a well, ask about softeners and sediment, which wear water heaters faster.
