Aside from the kitchen, one of the most renovated rooms in a house is the bathroom. Whether it is to reconfigure, so there is more room or to replace the bathtub or toilet. Most homeowners want a more comfortable space to get dressed in or to relax after work. If you’re replacing it, there are several options. But when you’re picking one out, you may want to know how does a toilet work?

How Does A Toilet Work?

New toilets are available with three different methods of operation. There are gravity-feed, pressure-assisted, and vacuum-assisted toilets.

Gravity-Feed Toilets

The most common model in homes, businesses, and other places where there are restroom facilities. After you’ve done your business and press down on the handle to flush the toilet, gravity helps push the water down into the bowl to remove waste.

Freshwater starts filling the tank as the flush valve empties. And as water increases, float ball rises too, cutting off the water once it gets to a certain level. The waste is washed down the drain into the sewer pipe and then moves onto the septic tank.

The toilet was first invented in the mid-1800s. Its tank was hung on the wall with a water pipe leading down to the toilet. This design used gravity to gave it the necessary power to flush away waste. There was a pull cord that hung from the water tank with which to flush the toilet.

Water Usage

Older gravity-feed toilets used several gallons of water, up to seven, depending on the model, but most units used between three and a half to five gallons of water. Flushing the toilet accounts for slightly less than 25% of the total water usage in most American households. In 1992, the federal government mandated that toilets should use no more than 1.6 gallons of water per flush to help conserve water. However, many manufacturers began to make design improvements to provide a better flush to eliminate waste.

Water tank outlet holes more formally called the flapper valve. Were made wider to increase the water’s flow into the toilet to help get rid of waste. The hole, the tramway, was also widened to prevent clogs. These designs made low-flush toilets work better.

New designs have made toilets even more efficient, with some models only using 1.28 gallons per flush (GPF), or less.

Pressure-Assisted Toilets

This is the second, less common type of toilet which exists in businesses like hospitals due to their cost. A good choice if you have a larger family. This information can also educate people about how their toilets work.

The flush of this toilet has a loud whoosh because the water stored in a sealed tank. The pressurized air helps force the water into the toilet. To sweep the waste down through the drain line.

It is important to check the water pressure in your home if you use this type. To ensure it operates correctly, your home should have a water pressure of 25 pounds per square inch (PSI). The water pressure is the measurement of the main water supply into your home.

If your water pressure is low and your neighbors aren’t, contact a plumber to check your waterlines. There might be water leaking from pipes.

Vacuum-Assisted Toilets

There is a separate vacuum tank that holds water inside of the porcelain outer tank. The vacuum tank connects the tramway. So that when the toilet is flushed, a suction is created in the vacuum tank.

After you flush, the inner tank fills with water. The air at the top of the inner tank is pushed down via a tube that runs into the tramway. It creates a bubble air between the water in the bowl and the tramway that opens the drain line. The bubble of air applies a downforce to the water in the tramway, which raises the water level in the toilet. The effects give the toilet more flushing power.

The vacuum-assisted toilet models that are available consume less water than 1.6-gallon low-flush toilets. Some models only need 0.8 GPF, which conserves more water than most other flush toilets on the market.

Dual-Flush Toilets

If you are tired of flushing more than once, you can purchase a dual-flush toilet. This type of toilet doesn’t operate differently, but it helps low-flush toilets work better by offering an option to flush the toilet for liquid or solid waste.

Most dual-flush toilets are pressure-assisted toilets that consume small amounts of water. There is a button or a lever that allows users to use a partial flush to get rid of liquid waste. The partial flush uses less than a gallon of water to remove waste and refill the bowl.

However, if you don’t want to buy a new toilet, older toilets can be retrofitted with a dual flush kit. You can install the kit yourself and have a plumber install one for you to save the amount of water that you’re flushing down the drain.

Toilet Designs

Modern toilets are available in four different types:

  • Two-piece toilets.
  • One-piece toilets.
  • Wall mounted toilets.
  • Smart toilets.

Two-piece Toilets

The standard toilet found in most homes is a two-piece. It comes with a water tank that fits into the toilet’s bowl. They are usually the most inexpensive option since they’ve been around longer, and most people buy them when installing a new toilet.

One-piece Toilets

A one-piece toilet has a tank and bowl that are connected as one-piece. They are usually easier to install and clean than two-piece toilets. They take up less room than a standard two-piece, so they are better for smaller bathrooms.

Wall Mounted Toilets

Instead of mounting a toilet to the floor, you can mount one to the wall. Many businesses with public restrooms have wall mounted toilets. They take up less space and, as long as there is a water source, they can be hung on any wall in the bathroom. However, they are among the more expensive options for toilets.

Smart Toilets

Smart toilets provide many different functions that standard toilets do not. There are models with:

  • Bidets
  • Heated seats
  • Self-cleaning wands
  • Hands-free flushing
  • Dual-flush options

Once you’ve answered the question how does a toilet work, you can make more informed choices when renovating or outfitting a new bathroom in a home or business.
