ABSTRACT:
The invention relates to a valve cover system in which the valve cover has a distinctive shape of a regular octagon and indicia identifying its function and relationship to the system it controls. In addition, the invention relates to a valve cover system which has a set of extensions on a valve cover socket so that the valve cover can follow ground movement and remain relatively level with the ground. Other improvements include a locking mechanism that inhibits removal of the valve cover thereby discouraging vandalism and a low friction telescopic extension to allow movement of the valve cover without damaging the conduit between the valve and the valve cover.
