The Anaotmoy of Toilets

The Siphon Tube

The bowl siphon is the s-shaped curve that drains the water from your toilet bowl. It has no moving parts, but instead holds the water in your toilet bowl through pressure. You can test the way it works by trying to flush the toilet immediately after you have just flushed it. Notice that the water level doesn't change and the toilet doesn't flush. However, if you wait until the toilet tank has refilled you'll see all the water flush out of the system like you normally do. You have to send enough water through the system to fill he siphon tube and create a vacuum. This is why you can also flush the toilet manually by pouring a couple of gallons of water directly into the bowl to cause the pressure change. Problems occur here when the tube becomes plugged.

The Flush Mechanism

The flush mechanism takes the place of manually using a bucket of water into the bowl to fill the siphon. Your tank normally fills withing a minute. When you flush, the water is dumped from the tank to the bowl in a few seconds. This fills the siphon tube and the pressure change causes the bowl to empty, carrying the contents of the toilet bowl out with the water. One of the most common causes of a toilet not flushing is the chain inside the tank becoming detached from the handle.

The Refill Mechanism

Removing the back cover of your toilet, you can see the mechanism that allows the toilet to fill with the proper amount of water. The key parts to proper tank refilling are the filler float and the drain cover. After a flush, the filler float no longer has the water to support its weight, so it sinks. As the filler float sinks, the valve is opened and fresh water begins to fill the tank. As the fresh water fills, the filler float will rise and once it has reached a predetermined point, the valve is closed and no new water flows in.

Many people have problems with this device. As it gets older or encrusted with minerals from hard water, the resistance the filler float faces can increase. If the buoyancy is no longer enough to lift it, the filler float can fail to rise enough to turn off the valve. In advanced cases, this can require the replacement of the assembly within the bowl. If you hear the toilet running constantly, but do not see water constantly running into the bowl, then this is likely your problem. If you see water running into the bowl, then the most likely culprit is a faulty drain valve.
