Abstract
This is a drain hose for a tank such as on a floor scrubbing machine and a means for attaching it to the tank. When not in use the hose is stored inside the tank, where it is protected from damage such as may occur to externally stored hoses. When it is to be used the hose is pulled from the tank and extended to a suitable site such as a floor drain and the contents of the tank are emptied through it. After use the hose may be pushed back into the tank again. The means for attaching the hose to the tank may include a cover over an opening in the tank which is amply large to permit cleaning out the tank.
