How Many Gallons Does It Take To Flush A Toilet

Many people wonder how many gallons does it take to flush a toilet. Some don’t even know how to calculate this. In this article, you will be provided with how to know how many gallons it take to flush a toilet.

The flush volume of a toilet simply means how much water is released when it’s flushed. To get this right you must be replacing a toilet currently using more than 1.6 gallons per flush. So, that means you need to know your toilet’s flush volume.

A label is typically located near the toilet seat hinge on the bowl that can provide you with that information. Please now that the markings and labels are often in liters as opposed to gallons.

Below is a quick reference to help determine your toilet’s flush volume if it’s listed in liters.

Gаllоnѕ Pеr Flush  Eԛuаlѕ Thіѕ Many Lіtеrѕ Pеr Flush

5 tо 7  18.92 tо 26.49

3.5  13.24

1.6 to 3.5  6.05 tо 13.24

1.6  6.05

1.28 (Note: If your toilet has a large black cylinder inside of it instead of the standard flushing mechanism, your toilet is using 1.6 gallons per flush and does not qualify for this post.)

If you cannot locate any labels near the seal hinge, check the underside of the tank lid or the tank’s back inside wall for a date stamped in the porcelain.

Still can’t find any labels? You can perform an easy test to determine how much water your toilet uses by flowing these simple steps.

Turn the water supply to your off. Not if you cannot turn the valve or do not have access to the valve simply prevent the toilet from refilling by holding up the flaot device in your tank.

  • Mеаѕurе thе lеngth of thе tаnk іn іnсhеѕ.
  • Mеаѕuring thе width оf thе tаnk іn іnсhеѕ.
  • Mеаѕurе thе full wаtеr lеvеl іn thе toilet tаnk in іnсhеѕ (depth 1).
  • Flush the tоіlеt аnd mеаѕurе the drор аt thе lоwеѕt level (dерth 2).
  • Subtrасt depth 2 from depth 1. Thіѕ will gіvе уоu thе “drор” measurement.

Overview Of All I Said Earlier

Toilets are hardly the most glamorous of inventions, but imagine trying to live without them. About 40% of the world’s population are in that unhappy position, lacking even basic sanitation.

At the opposite end of the scale, in some developed countries, like Japan, U.S, people have amazing electronic toilet that do everything from opening and closing the lid automatically to playing music while you use them. Most of the world’s toilets are more modest than this, but they’re still pretty ingenious machines.

For instance, like most new toilets, the low-flush model is designed to save water, the two buttons on top let you choose whether to flush with a large or a small amount. Exactly how much difference that will make to your water consumption varies from one household to another.

An older-style flush toilet typically uses 13 liters( 3.4 gallons), where a low-flush mode will use only 6 liters (1.6 gallons) and some models use only 4.8 liters (1.3 gallons). If you save 7 liters (1.8 gallons) per flush and people in your home flush 10 times a day, you will save at least 25, 000 liters(6700 gallons) per year.

Flush Toilets

At first sight, toielts seem quite simple; you have a waste pipe going through the floor and a tank of water up above called a cistern waiting to flush into it when someone pushes a button or pulls a lever or a chain. As I said earlier, most flush toilets are purely mechanical: pull the chain and the cistern empties through the force of gravity.

Washing the bowl clean for use again. They are literally mechanical because they flush and refil using levers inside and levers are examples of what scientists call “Simple Machines.”

Tip: lift the cistern on a toilet and there is something you will find inside. The cistern (upper tank of water) drains through a valve in the center through the force gravity. The valve and flushing mechanism in the middle is called the siphon.

The blue, balloon-like object on the left is a plastic float drops when the water level falls. This tilts the white plastic lever, opening a ball valve( sometimes calls a ball cock) and allows the cistern to refill. As the water rises, the float rises with it, tilting the lever and slowly shutting off the ball valve.

What Happens When You Flush?

Press the handle to flush the toilet and you operate a lever(dotted line) inside the cistern. The lever opens a valve called the flapper that allows the cistern to empty into the toilet bowl beneath through a mechanism called siphon. Water flows from the cistern through in the rim so it washes the bowl as well as flushing the contents away.

There’s enough water flowing down from the cistern to flush the toilet around the S-bend(S-trap). This produces a siphon effect that sucks the bowl clean. It also ensures some water remains at the bottom of the bowl, which improves hygiene.

The contents of the toilet are flushed down the remain drain. As the cistern empties, the plastic float falls downward, tilting a lever. The tilting lever opens the ball  valve  at the base of the cistern, which works a bit like a faucet. Pressurized water flows in, refilling the cistern, and pushing the float back up again. When the float reaches the correct level, the ball valve switches off the water supply and the toilet is ready to flush again.
