Local plumbing issues in Seattle
Side sewer repairs
Seattle homeowners own their side sewer to the main, and older clay lines often need repair.
Heavy rain
Wet winters test basements, drains and sump pumps.
Earthquake readiness
Water heater strapping and flexible connections reduce damage risk.
Rain and steep lots
Seattle's many hills mean side sewers run down steep yards, and long wet seasons saturate soil around older clay pipe.
Soft water
Seattle's mountain water supply is soft, so scale is rarely a problem, but older galvanized pipe still corrodes.
Older Craftsman homes
Early 1900s Craftsman homes often have basements with plumbing added or rerouted over the decades.
