This Viva Side Entry Ball Valve is a component for residential plumbing systems, specifically designed to control water levels within a cistern. The valve features a height-adjustable arm that allows for precise calibration of the float mechanism to ensure reliable water shut-off. It includes a pivoting thread designed for the attachment of a ball float, which is required for the valve to function correctly. This side-entry configuration is intended for plumbing installations where the water supply enters through the side of the cistern tank.
