A toilet flange is an important part of the toilet. It is the point at which the toilet unit connects to not only the floor, but the piping that runs into the sewer. An ill-fitting toilet flange can cause leaking, leading to weakened and even rotted boards in the bathroom around the toilet.
Significance of Toilet Flange
Features of Toilet Flange
A flange is circular flat piece of rubber, PVC or metal that has hole drilled in intervals around the top of the circle through to the bottom. These holes are for the hold-down bolts used to hold down the toilet. Some toilet flanges come as the circular piece alone, while others are connected to PVC elbow joint. The elbow joint connects to the piping system, eventually leading to the sewer.
How a Toilet Performs
The toilet flange's job begins not when the water and waste exit to the sewer, but when the user pushes down on the toilet lever to initiate a flush. This raises either a flapper or ball up from the flush valve. Water from the tank then rushes into the toilet bowel. The flapper is connected by chain to the lever. While the water is running out of the tank, the flapper is lowering until the tank is empty. This activates a ball cock, which fills the tank once again.
Function of Toilet Flange
As the toilet flushes, the water released from the holes under the rim of the toilet bowl pushes water and waste from inside the bowel and up through the porcelain trap and down into the drain. Both gravity and suction caused by the sealed flanged connecting the toilet to the floor cause the water and waste to rush down into the drainage system.
With the many uses a toilet gets, a flange is a very important component indeed. Proper maintenance is key, because replacing a faulty flange is a very difficult task.
