Repiping in New York, NY
Repiping replaces a home's water supply lines, usually because old galvanized steel has corroded or polybutylene is at risk of failing. Most repipes today use PEX, take two to five days, and are done through small wall openings rather than gutting the house.

Repiping for New York homes
Many homes built before the 1960s still have galvanized supply pipe, which rusts from the inside until pressure drops and the water turns brown. Some homes built between the late 1970s and mid-1990s have gray polybutylene pipe, which can fail at fittings without warning.
For the full guide, including what you can safely do before a plumber arrives, see repiping explained.

Repiping in New York: what's different
Pre-war New York buildings often still have galvanized or early copper supply lines and risers. Galvanized corrodes from the inside, causing low pressure and rusty water, and building-wide riser replacements are planned in phases by management.
In brownstones and rowhouses, a repipe is the owner's project and often happens during a renovation when walls are open anyway. Most plumbing work in NYC must be performed under a Licensed Master Plumber, with permits filed with the Department of Buildings.

- Licensed master plumber rules: Most plumbing work in NYC must be performed under a Licensed Master Plumber, so check the license before hiring.
- Aging risers and drains: Old cast-iron stacks and galvanized supply in pre-war buildings leak and clog.
- Freeze risk: Pipes near exterior walls and in unheated spaces freeze during cold snaps.
- Water from upstate reservoirs: New York City's water comes from the Catskill, Delaware and Croton reservoir systems and is soft, so scale is less of an issue than leaks and aging pipe.
