About One Way Plumbing


About One Way Plumbing

We specialize in design build plumbing systems for multi-family and mixed-use buildings. Our work has been primarily in Multiple Unit Apartments, Condominiums, Retirement Centers and Light Industrial Centers.

Our family of plumbers and office staff has been working together for many years. We believe in doing things correctly and safely therefore we keep all our plumbers up to date on current plumbing code and site safety requirements. During the COVID construction shutdown we paid our plumbers for their time to take extra safety classes. Our lead construction manager is a Unified Plumbing Code continued education course provider approved by the Department of Labor & Industries.

We meet regularly with manufacturers in the industry to keep up to date on the latest and best plumbing products and procedures and incorporate those into our jobs.

We are active members of IAPMO (International Association of Plumbing and Mechanical Officers). IAPMO protects the public's health and safety by working in concert with government and industry to implement comprehensive plumbing and mechanical systems. We are also current members of the Master Builders Association (MBA) of King and Snohomish Counties. MBA advocates on the federal, state and local levels and assists with permitting and regulatory issues.
