HydrocraftPlumbing Solutions, Seattle, home

Commercial plumbing for Seattle restaurants, buildings and offices.

Commercial work is scheduled work: backflow tests due every year, grease traps the health inspector wants to see, a building's worth of water heaters on a replacement plan. We put it on a calendar so nothing is a surprise, and we come out of hours when a kitchen can't close.

Restaurants and cafés

Grease interceptor cleaning and replacement, floor drains and floor sinks, pre-rinse faucets, dishwasher booster heaters, and the annual backflow test SPU requires.

Multifamily and HOAs

Unit-by-unit repairs billed to the association, recirculation pumps, boiler and water heater replacement, and stack cleaning on a schedule.

Offices, clinics and retail

Restroom fixtures, break-room plumbing, tenant improvement rough-in and the permits that come with it.

“They test our backflow assemblies every spring and handled the grease trap when the health inspector flagged it. One invoice, no drama.”
