We have had a continuing problem with a traditional float and ballcock system. The slow cut off at a low flow rate meant that the pump on our water tank was cycling on and off as the level approached the top and then the pump would cut out. Late at night in the rain is not the best time to be resetting the pump. This new float system with a sharp cut off has solved the problem. Thanks very much.
Do be careful to follow the directions on setting the levels and remember to lock down input tube length.
