What’s different about pipe repair in Washington
Galvanized supply
Corroded galvanized pipe causes low pressure and rusty water.
Rear additions
Additions often have less insulation and are the first to freeze.
Renovation timing
Many DC rowhouses are renovated in stages; replacing old supply lines while walls are open saves cost and disruption later.
Homeowner checklist
- Know where the main shutoff is in the basement
- Insulate pipes in rear additions
- Check for rust-colored water
- Check DC Water’s service line map

Is PEX allowed in DC homes?
