How Does a Toilet Tank Work?

Have you ever had a clogged toilet? One of the worst things about it is you don't know what's happening. Where did the water go? How does it get there? What's beyond that white tank behind the toilet? It's scary, especially for new homeowners. So we're going to talk about how a toilet works. After reading, if you still feel an issue with your toilet, contact Mr. Rooter Plumbing, and we will be happy to send someone to assess the situation.

What Are The Parts Of a Toilet?

Toilets are simple devices, but they have a lot of parts. There are many different types of toilets, each with different parts, and most toilets have these things in common:

  • Handle: You use the handle to flush the toilet. The handle is attached to a chain that runs through the center of the toilet tank and connects to a flapper. As you push down the handle, the chain pulls up on the flapper and opens it up so water can flow into the bowl. Gravity closes the flapper when you release pressure on the handle, stopping water from draining out of your toilet's tank. Handle arms attach to handles and connect them to chains differently depending on whether they're used with ball-type or flush valve-type toilets.
  • Ball: Ball-type toilets have a ball instead of a flapper inside their tanks. When you press down on your handle, it pushes against spring pressure inside the tank until it raises enough for water to flow out through holes in its bottom opening (the "drain opening").
  • Tank: The tank is where water collects when the toilet isn't being used and then releases the stored water into the bowl when needed. It's made up of two parts: an upper tank that holds most of the water and a lower tank with an overflow tube to direct excess water into the bowl when needed.
  • Bowl: The bowl is where waste goes after being flushed down the drain line. Waste travels down this line until it reaches clean water, at which point it stops traveling until someone flushes it again. The inside shape of the bowl is called its "water-holding capacity."
  • Chain: The chain connects from under the rim of your bowl to release water into the bowl when you push down on its lever (or handle). When this happens, it allows water to flow through your fill valve into your tank until it reaches its maximum level (known as full-flush capacity). It stops releasing water until you push down your lever or handle again.
  • Handle: The handle allows you to flush your toilet by pulling up on it so that it lifts against a chain inside the tank, moving a rod called a flapper behind it that opens up holes in your tank bottom to allow water to pass through them into your bowl below.

How Does a Toilet Tank Work

  • Toilet tanks come in various shapes and sizes, but they all serve the same purpose — to store water. A toilet tank is a reservoir that holds your toilet's fresh water supply.
  • Toilet tanks are usually made of plastic but can also be made of porcelain or stainless steel. They have a float valve that keeps the water level inside the tank constant, even when someone flushes the toilet. The float valve also prevents you from running out of fresh water while using your toilet.
  • The tank sits on top of the bowl and contains two hoses: one for inputting water and one for outputting waste. The input hose is connected to your home's main line through a shut-off valve on the outside wall near your toilet. The output hose carries waste from your home's sewer line into your septic or municipal sewer system.
