Backflow & Code Compliance in Seattle, WA

Xion Build provides expert backflow & code compliance in Seattle. As a trusted Seattle plumbing contractor, we manage design, materials, permits, and every trade in-house so your project stays on schedule and on budget. Backflow prevention and bringing plumbing to code.

From Laurelhurst to Queen Anne, Seattle's older homes often need structural care alongside the kitchen, bath, and addition work that modernizes them.

From re-piping and tankless water heaters to fixtures, drain lines, and radiant heat, we coordinate rough-in with tile and cabinetry so everything lands where the design intends.

What's included in your backflow & code compliance
