A manual head is the simplest marine toilet to run. It has no motor to wire and no fuse to size, and it works with a flat battery. The trade is effort: you pump the handle for every flush. Most of these heads can be mounted above or below the waterline and discharge overboard or to a holding tank. Many makers do not publish how much water a flush uses, so that factor often shows as estimated.
