Sumner is a small Pierce County city next to Bonney Lake and Lake Tapps, with a mix of older downtown housing and newer subdivisions on the surrounding hillsides. Downtown homes near Main Street have a stock of 1910s through 1940s construction where galvanized repipes and cast iron drain work come up regularly. The streets toward Lake Tapps and the Bonney Lake border lean newer with more water heater and tankless service. Every plumber listed here serves Sumner and is verified active with the Washington State Department of Labor and Industries.
