The yellow, easy-to-access service lid covers a JFC fast-fill float valve which comes with a 3/4inch connection and is capable of delivering up to 175L/min (3 bar pressure). Fast fill valves mean a larger herd can be supplied with water without need for increasing trough sizes. This valve operates in a 'fully on fully off' manner unlike conventional valve which restricts flow and slowly reduces flow until a delayed stop. It is fitted with a drain off for easy emptying and cleaning. This water trough comes with fully adjustable and accessible valves that comply with water safety regulations. It is stable in UV light and easy to clean. JFC's 90 gallon water trough is suited to fit between two fields or pens due to its double reservoirs and central housing design. Water capacity is 400 litres. High quality plastic trough means it can withstand extreme climate conditions ensuring long life span. It is stable in U.V. light and is easy to clean. Suited to sheds and pastures. This trough is easy to transport and move around. Frost resistant polyethylene.
