In fact, Sir John Harington is credited with having BOWL invented the "John" nearly 300 years earlier. The most crucial piece of the toilet is what is molded into the bowl, known as the bowl siphon, shown here: Did You Know? Contrary to popular belief, the toilet was not invented by Thomas Crapper. BOWL SIPHON FLUSH FACTS: Despite having no moving parts, the toilet bowl features a highly functioning design. Let's take a look at what happens when you flush a standard toilet as well as how some of its components work. How a Toilet Works When You Flush Nowadays, having a functioning toilet in your home should not get you too excited. The flapper is a rubber mechanism that acts as a seal to the drain, it both lets water in and out of the tank when you flush, pretty nifty. If there were no refill tube, there would only be a small amount of water in the bottom of your toilet which could become a problem! The overflow tube empties directly into the toilet bowl below, refilling the bowl after a flush. The refill and overflow tube work together to help keep water in the tank. When the tank is empty, the float ball falls freely allowing the valve to open, filling the tank. When the water reaches a certain level in the tank, the ball floats level on the water, shutting off the refilling mechanism. The float ball is connected to the fill valve that controls the water flow to the tank. As the water leaves the tank and enters the bowl, it fills the toilet bowl and the siphon effect occurs, resulting in removal of water and waste.Īs the tank is empties, the flapper covers the drain hole and water comes into the tank to refill it. By lifting the flapper up, the water inside the tank is allowed to flow down into the toilet bowl. Once you push the handle, the chain that is connected to the flapper and flush valve is pulled up by the handle arm. I invented the first flush toilet in 1596
His sanitary engineering company created and patented parts of the modern day toilet such as the float ball seen below. On the other hand, Thomas Crapper was a plumber and a big advocate of water sanitation. Not only did Sir Harrington come up with the idea of the toilet, but he actually installed an early working prototype in the palace of Queen Elizabeth I who happened to be his godmother. In fact, Sir John Harington is credited with having invented the "John" nearly 300 years earlier. The same effect can be achieved by the siphon alone as long as you pour enough water quickly into the bowl.Ĭontrary to popular belief, the toilet was not invented by Thomas Crapper. When you push the handle down, the tank system is activated causing water to dump into the bowl in less than 3 seconds triggering the flush. More importantly, the tank can send the water fast enough into the bowl to activate the siphon effect and send waste and water down the pipe. The tank located in the upper part of the toilet holds about 2 gallons of clean water. The bowl is then refilled with water from the tank above. The air coming into the bowl stops the siphoning process. As water and waste leave the bowl on flush, air rushes in causing the "flush" sound. The bowl is attached to a pipe with a U-bend that leads into a sewer system. The most crucial piece of the toilet is what is molded into the bowl, known as the bowl siphon, shown here: Let's take a look at what happens when you flush a standard toilet as well as how some of its components work.ĭespite having no moving parts, the toilet bowl features a highly functional design.
