What’s different about pipe repair in San Francisco
Tight chases in flats
Pipes run through narrow chases between units, which affects access and repair approach.
Galvanized supply
Old galvanized pipe narrows, causing low pressure and rust.
Permits
Repiping requires permits and inspection.
Homeowner checklist

Pipe Repair in San Francisco: questions
Is PEX or copper better for repiping a San Francisco Victorian?
Both work; PEX is often chosen for easier routing through old walls with fewer openings.
Why is my upstairs flat’s pressure low?
Corroded galvanized risers restrict flow, and upper floors feel it first.
Can repiping be done while tenants live in the building?
Yes, usually in stages with water off during working hours.
Do San Francisco tenants need to move out for a repipe?
Usually not. Work is typically staged so water is off during working hours and restored at night.
