Auto Mains Tank Valve

LiquiLevel AV automatic valve is ideal for water tanks which are filled with mains water or a pressure system controlled by a pump. The AV valve gives a level difference which is adjustable from 50mm to 2500mm which minimises starting and stopping of running water or the pump system which helps prolong the life of both pumps and valves. This automatic valve is also designed for use with Rainwater harvesting systems as a automatic mains top-up valve, when there is not enough rainwater available within the tank.
