Plumbing in Pre-War Manhattan Buildings: Risers, Cast Iron and Repiping
Many Manhattan buildings were built before modern plumbing materials. Original cast iron drain stacks and older supply risers can corrode over time, and fixing them usually involves the whole building, not a single unit.
Signs you need this service
- Repeated leaks from the same stack
- Rusty water building-wide
- Slow drains across several floors
- Visible corrosion on exposed riser sections
How the job works
- Inspect the stack or riser, including camera inspection of drain lines.
- Plan the sequence with the managing agent so shut-offs are scheduled.
- Replace sections or full risers with suitable modern pipe.
- Restore service and provide documentation to the building.
Frequently asked questions
Who pays for riser replacement?
This depends on the building and your governing documents. The managing agent or board can tell you who is responsible.
How long is the water off during riser work?
It depends on the scope. We agree the shut-off windows with the building in advance.
