This water trough always contains ample drinking water. Thanks to an automatic system fitted with a float valve, also known simply as a ‘float’.
Farmer Dick made a conscious choice for this water system. Cows live in herds, which are groups based on a hierarchical structure. A large water trough offers all cows equal opportunity to drink at any time. They do not have to wait their turn to drink, as would be the case with a water dispenser.
