Plumbing conditions in Delaware
Delaware has hot, humid summers and cool winters with periodic hard freezes. Its low-lying coast is exposed to tropical storms and coastal flooding.
Homes range from older rowhouses in Wilmington to newer suburban construction, with both basements and slabs common.
Delaware 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 Delaware
Frozen and burst pipes
Cold snaps in Delaware 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 →Flooding and sewer backups
Heavy rain and flooding in parts of Delaware push water into basements and back up older sewer laterals. Backwater valves and sound laterals reduce the risk.
Sewer line repair →Basement backups and sump pumps
Many Delaware 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 →Aging pipes in older homes
Older homes in Delaware often still have galvanized supply pipe, cast-iron drains or clay sewer laterals, which corrode, crack and collect roots with age.
Repiping →Where plumbers are covered in Delaware
