Cistern system, apparatus and method

Abstract

A cistern system enables maintenance, removal, or adjustment of various components through a maintenance window. The cistern system includes screen support members that cooperate with a flush valve to remove fallen components. The cistern system includes a frame with an adjustable upper bar that can be removed to facilitate the installation of various components. The frame includes a bar holder fastener that enables vertical leveling when the frame is secured to a wall with one or more wall mounts. The frame includes adjustable frame supports that can be fixed in position by frame height adjusters when only supporting the weight of the cistern system but can be adjusted in and out of the frame by applying additional downward force to the frame.
