The toilet float rod is also a quite self-explanatory piece. This piece functions directly with the float ball, by holding it in place. This piece is vital to the proper functioning of the toilet float ball.

The float rod can be positioned either horizontally or vertically. If it is horizontal, it is attached at the fill valve cap and leads to the float ball. This positioning keeps the float ball high and is ideal for toilets that need increased water volume inside the tank. If the float rod is position vertically, it is attached directly to the flush lever, leading down to the float ball. This position keeps the ball low and is best for toilets that do not need lots of water, or for people who want to save on water.
