You can tell if a toilet is an automatic or regular style by looking at the bowl. Automatic toilets have a sensor that triggers the flushing of the water after someone sits down on the seat. Regular toilets do not have sensors and need to be flushed manually. Also, regular toilets do not have sensors to heat up the seat as some automatic models do. In this article, you will read about how to make an Automatic toilet Flush.
No, not all automatic toilets have a manual button. Many of the newer models do not have a manual button. The volume of water and the timing of how long it takes to fill up is controlled with an electric timer and there is no way to lower the water level or stop it from filling up. Older models usually have a manual button that can be pushed down with your foot to drain out some of the contents if you need to use less water for flushing.
How does an automatic flush toilet work?
Automatic toilet flush valves have a float that closes the flapper valve after you use the toilet. The float is connected to a t-stat.
There are two kinds of t-stats: the standard model has screws on the bottom that can be adjusted to increase or decrease the pressure in the tank, while the aneroid model has an air bubble inside that goes up and down with your flush. Some toilets have both air-bubbler and screw-adjust models for greater adjustability.
Simply put, the toilet has a tank full of water which gets flushed out with each flush. There are several different types of automatic flushing toilets. You can tell a flush toilet from a non-flush toilet by looking at the bowl.
Older models usually have a closed bowl you would have to pull to retrieve waste and that is why it is called an “automatic.” Newer models have an open bowl, so you can see inside after you pull the long lever to flush.
Usually, also on newer models, there is a closed hose on the outside of the tank which goes back up into the tank and connects to another hose you use to clean out your bowels after using the toilet. An automatic flush toilet gets the water to the bowl from a tank on top of the bowl called a cistern.
The cistern is filled with water from the main supply line. The water is pumped into the bowl from a pump connected to a timer and is flushed down the drain when you push down on the lever handle which springs back when you release it.
Some models have automatic flush toilets with no moving parts besides an electric timer and a lift pump that pumps up and down, while some models then use an electric motor for pumping instead of a hand pump or foot pump. They usually sell for more than $100 USD, but there are models available for less money that also work fine.
How to make an automatic toilet flush
Automatic toilets uses sensors to know when somebody has finished using the toilet and will then flush. The sensors are usually either:
- A weight sensor – this is a spring-loaded plate located in the bowl of the toilet. When someone sits on it, it will move down and trigger a switch. It then detects that an additional person is no longer on it and returns to its original position to reset itself.
- A motion sensor – this uses the same principle as the weight sensor, but instead of relying on gravity to keep it in place, it is activated by motion. There is usually a light on top which turns on when the toilet is used and lights off when the toilet seat has been left up.
The issue with both of these sensors is that they can be used in other ways. to make an automatic toilet flush you need to make sure the sensors can detect the right thing to trigger.
Automatic toilets will also have a display timer that will count down the amount of time you have been sitting on the toilet. Because not everybody queues up at once for a public toilet, a timer is required to make sure people don’t leave and come back later.
For example, if there were 3 toilets in one room with three timers, it’s possible for one person to queue up while someone finished using a toilet moments ago and then they leave before them and don’t get counted into the total usage.
Why do automatic toilets exist?
One of the main reasons why automatic toilets exist is the fact that they are hygienic toilets. Without the need to touch the handle, germs are kept at bay from coming into contact with your hands.
This prevents cross-contamination and also reduces the risk of having any kind of disease being passed on. A lot of people get sick from not washing their hands properly in public toilets and that is why there are automatic ones for home use. Another reason why automatic toilets exist is they are convenient.
When your hands are full such as with shopping bags, you do not have to touch anything before or after you flush. The toilet takes care of everything and a lot of people like them because they are easy to clean and do not take up too much space. With an automatic toilet at home, you do not have to worry about getting sick from germs that may be lingering around the toilet.
