of container 10 by means commonly known in the art the water level gauge includes a water level gauge hose 23 that runs through a sidewall of container 10 a cap unlabeled comprising a central opening through which projects a water level gauge such as a tube or rod hydrostatic forces cause fluid to move in and out of the portion of the water level gauge hose 23 that is disposed in said first container 10 thereby causing a bulb unlabeled floating within gauge 22 to rise when installed in a water container chamber the float rises and the gauge such as a tube or rod extends out the central opening in the cap the gauge may carry indicia to give a measurement of the height of the water in the first container 39 s chamber returning to fig2 an additional container 32 is shown adjacent to said first container 10 tubing 24 fluidly connects the two containers which are at varying elevation as more clearly shown by a brief review of fig1 the tubing is attached to nipple 28 on one end and to tee 31 which may also function as an elbow with a cap 31 c thereon for use in the case where no further additional containers 32 with their interior chambers 40 are daisy chained together if a second or additional containers 32 were to be attached another segment of tubing 24 similar to that shown here would.
