Local plumbing issues in Wilmington

01

Rowhouse basement backups

When an old lateral clogs, the basement floor drain is where water shows up first, often in the laundry area.

02

Frozen pipes in rowhouse basements

Pipes along front walls and in unheated vestibules freeze during cold snaps, especially in vacant units.

03

Older service lines

Many Wilmington homes have older water service lines, and the city has been inventorying lead service lines as federal rules require.

04

Shared rowhouse drains

Some older Wilmington rowhouses share a drain line with the house next door before it reaches the street, so a clog or repair can involve both owners. A camera inspection shows where the shared section runs.
