Before the homeowner begins the job of installing the new toilet, they need to make sure they have everything handy that the process requires. Most toilets come with all of the parts needed to make it work. The flange, lever and ball system that is how the flush system works are usually included with the purchase of the toilet. A wax or rubber gasket is needed for where the toilet hooks up with the drain in the floor. These are a standard size and easily available. This part may require two or more people to assure that the toilet is lined up properly before seating it on the gasket. Hooking up to the water supply line is simple, as there is only a cold water line.
