The standard size for a toilet drain pipe is 3 inches in diameter, but drains up to 4 inches in diameter are often used. The drain pipe connects to the flange, which mounts the toilet itself, and this flange is usually built to connect to 3-inch, schedule 40 toilet drain pipe.
This system is suitable for locations plumbed with 1â2 inch (13 mm) or 3â8 inch (9.5 mm) water pipes. These small diameter pipes cannot supply water quickly enough to flush the toilet; the tank is needed to supply a large volume of water in a short time. The storage tank is kept full by a tank fill-valve.
