For a clogged drain, start with the gentlest methods: a plunger, removing and cleaning the stopper or visible debris, or a drain snake for hair and gunk near the surface. Avoid harsh chemical drain cleaners — they can damage pipes and rarely fix the real blockage. If multiple drains are slow at once, or the clog keeps returning, that points to a deeper line or main sewer problem that needs a plumber.
Most single clogged drains are caused by something near the surface — hair in a bathroom drain, food and grease in a kitchen sink — and respond to simple methods. A cup plunger creates pressure that often dislodges the blockage. Removing the stopper and pulling out visible hair and debris clears many bathroom clogs.
A hand drain snake (auger) reaches a little deeper and grabs clogs a plunger cannot, and it is inexpensive and reusable. For kitchen sinks, hot water and dish soap can help with grease, and a plunger often does the rest.
One strong piece of advice: avoid harsh chemical drain cleaners. They are caustic, can damage older pipes (common in NYC buildings), are hazardous to handle, and frequently do not clear the actual blockage — leaving you with a still-clogged drain full of dangerous chemicals when the plumber arrives. Mechanical methods are safer and more effective.
Pay attention to the pattern. A single slow drain is usually local. But if several drains are slow at once, water backs up in odd places (the tub gurgles when you flush), or a clog keeps returning no matter what you do, the problem is likely deeper — in the main line or sewer — and that needs a plumber with proper equipment.

Should I use chemical drain cleaner?
It's best avoided. Harsh chemical cleaners can damage pipes, are hazardous to handle, and often don't clear the real blockage. A plunger or hand snake is safer and usually more effective.
When is a clogged drain a bigger problem?
When multiple drains are slow at once, water backs up in unexpected places, or a clog keeps returning — these point to a deeper main line or sewer issue that needs a plumber.
What's the best way to clear a hair clog?
Remove the stopper and pull out visible hair, then use a hand drain snake to grab what's deeper. A plunger can help dislodge the rest.
