How Does a Toilet Work? 

You’ve probably never thought about how your toilet works. As long as everything is working correctly, many people don’t bother questioning the magic behind the flush. But understanding this seemingly simple plumbing fixture can be fascinating and even helpful if something goes wrong.

Here at Mr. Rooter Plumbing, we take pride in being the go-to toilet installation experts. Our highly trained plumbers understand the fascinating anatomy of a toilet, inside and out. In this guide, we will help you understand how toilets work.


A toilet tank houses a number of components that work together to efficiently flush waste. They include:

  • Fill valve: As the name implies, a fill valve allows water into the tank after a flush. It works together with a part known as the float to refill the toilet after it’s flushed.
  • Toilet flapper: This part sits on the flush valve, and it’s responsible for preventing the water in the tank from flowing down into the bowl. When the toilet is flushed, the chain pulls up the flapper, thereby opening the flush valve. This action allows water to rush down into the toilet bowl.
  • Flush lever: This piece works together with the flush handle to initiate the flushing action. When you press the handle, the lever arm lifts the toilet flapper, allowing the tank to flow into the bowl.
  • Flush valve: Located at the center of the tank, a flush valve is the part of a toilet’s anatomy that releases a large volume of water when the toilet is flushed.

All of these components can develop a wide range of problems, including misalignment, leaks, clogs, breakages, and many more. If you notice a problem with your toilet tank, call a top-rated plumbing repair service for a professional inspection.


This is the round or elongated vessel where the user sits. Its design allows waste to be deposited into the bowl so that it can be flushed down the drain.

Toilet Flange

A toilet flange, also known as a closet flange, is a pipe fitting that secures a toilet to the floor and connects it to the drain pipes. The fitting is secured to the subfloor with screws or bolts before the finished flooring material is installed.

Wax Ring

This is a ring-shaped piece made of waxy material that forms an airtight seal to prevent leaks. A faulty wax ring can lead to toilet leaks around the base and allow sewer gases to seep into your bathroom. If you’ve noticed a problem with your toilet’s wax ring, reach out to a reputable plumbing repair service for an inspection.

Common Toilet Problems

If you’ve got a toilet, there’s a good chance you’re going to encounter toilet problems at some point. Some of the common toilet problems include:

  • Leaking toilet
  • Broken handle
  • Slow-filling toilet
  • Clogged toilet
  • Running toilet
  • Toilet won’t flush properly
  • Wobbly toilet

If your toilet is not functioning as it should, schedule toilet repair service as soon as possible to prevent further problems. Reach out to a professional plumbing company that specializes in toilet plumbing to help you out.
