Plungers - Most People Have the Wrong One

There are three types of plungers and they're not interchangeable. A NYC plumber explains which one you actually need.

Invented 1850s by Unknown - rubber suction cups date to the 1850s

Pro Tip from 30+ Years

Run the plunger under hot water for 30 seconds before using it. This softens the rubber and creates a much better seal. Cold, stiff rubber doesn't conform to the drain opening.

Fun Facts

  • The classic red rubber cup plunger that everyone owns is actually a SINK plunger. It doesn't work well on toilets because it can't seal around the drain opening.
  • Plungers work by creating pressure changes in the drain pipe. The push compresses air/water, the pull creates suction. The seal is everything - no seal, no pressure, no clearing.
  • Most plumber emergency calls for toilet clogs could have been solved with the right plunger used correctly. The flange plunger exists for exactly this reason.

Three Plungers, Three Jobs

Most people own one plunger - the red rubber cup on a stick. And most people use it for toilets. It barely works for toilets. Here's why, and what you actually need.

Cup Plunger (Flat Plunger)

The classic red cup. This is a sink and tub plunger. The flat rubber cup creates a seal on flat surfaces - the bottom of a sink, the floor of a bathtub. It does not seal well on the curved drain opening of a toilet bowl.

Cost: $5-$10. Get one for the kitchen and bathroom sinks.

Flange Plunger (Toilet Plunger)

This looks like a cup plunger with an extra rubber flap (flange) folded inside the cup. That flange extends down into the toilet drain opening and creates a proper seal. This is what you use for toilets. The flange fits into the drain hole, the cup seals around it, and you get the pressure differential that actually clears the clog.

Cost: $8-$15. Every bathroom should have one stored next to the toilet.

Accordion Plunger

A hard plastic plunger with accordion folds instead of a rubber cup. Generates more force per push but harder to seal and harder to use. I don't recommend these for homeowners - they're aggressive and can crack old porcelain on NYC pre-war toilets.

How to Actually Use a Plunger

The technique matters more than the tool:

  • Ensure water covers the plunger cup. If the bowl is empty, add water. The plunger needs water to transmit force - plunging air does almost nothing.
  • Get the seal right. Press the cup/flange firmly against the drain opening. You should feel resistance when you push.
  • Push and pull with equal force. People focus on the push, but the pull creates suction that's equally important for clearing clogs.
  • 15-20 strokes before giving up. Don't do three half-hearted pumps and call it failed. Give it real effort.
  • If it won't clear after two rounds: stop. Continued plunging on a hard clog can push it deeper or damage wax seals on toilets.

    • NYC Apartment Reality

    Small NYC bathrooms mean limited storage, so people skip buying the right plunger. Keep a flange plunger in each bathroom. When a toilet clogs at 11 PM on a Saturday in Manhattan, a $12 flange plunger beats a $350 emergency plumber visit every time.
