Washington gets periodic hard freezes and ice storms, often after mild spells, which catch exposed pipes off guard. Pipes in crawl spaces, exterior walls and garages are the first to freeze.

Common plumbing problems in Washington
Frozen and burst pipes
Cold snaps in Washington freeze pipes in exterior walls, crawl spaces and garages. A frozen line often splits and leaks only after it thaws, so shut off the main if you see water.
Frozen pipe thawing →Aging pipes in older homes
Older homes in Washington often still have galvanized supply pipe, cast-iron drains or clay sewer laterals, which corrode, crack and collect roots with age.
Repiping →Basement backups and sump pumps
Many Washington homes have basements, where the floor drain is the first place a sewer backup shows up and a sump pump is the main defense against groundwater.
Sump pump service →Earthquake readiness
Washington is seismically active. Strapped water heaters and flexible gas and water connections reduce the chance of leaks and gas line breaks in a quake.
Water heater replacement →Private wells and septic systems
Many rural Washington homes rely on private wells and septic systems. Pressure tanks, well pumps and septic lines need a plumber familiar with those systems.
