Drain cleaning in New York, NY
If one fixture is slow, the clog is usually in that fixture's branch line. If several drains back up at once, or the basement floor drain fills when you run the washer, the main sewer line is blocked and needs a larger cable or a jetter.

Drain cleaning for New York homes

Local conditions
Drain cleaning in New York: what's different
Most New York City drain clogs happen in old cast-iron lines in pre-war buildings, where decades of scale narrow the pipe and catch grease and debris. In co-ops and condos, the building usually owns the main stacks while the unit owner owns the branch line from the sink or tub, so management may need to be involved.
A plumber clears the branch line and, if the clog is in the stack, coordinates with the building. Houses and rowhouses in the outer boroughs have their own laterals to the DEP sewer, which the owner is responsible for. Most work must be done under a Licensed Master Plumber.

- 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.

Why is my basement floor drain backing up?
When water comes up through the basement floor drain, the main sewer line is usually blocked between the house and the street. Stop using water upstairs, then call a plumber to clear the main line. If it happens more than once, a camera inspection shows the cause.

Should you get a sewer scope before buying a home?
For homes built before about 1980, or with large trees in the front yard, a sewer scope is worth it. A standard home inspection doesn't look inside the sewer line, and in most U.S. cities the buyer will own that line, often all the way to the main.
Emergencies
Sump pump not working? Causes and fixes
Check power first, then the float: if it's stuck against the pit wall the pump won't start. A pump that runs but doesn't empty the pit often has a frozen or clogged discharge line or a stuck check valve. If the pit is about to overflow, call right away.
