OK needs some help here and i'm not sure how to accomplish this. Basically i have 2 pumps (fill and drain), a resevoir and a bucket. What i want to happen is that i want to fill the bucket from the resevoir up to a point and then as soon as it reaches that point turn the fill pump off and turn the drain pump on. Drain to a point at the bottom and then turn the drain pump off and the fill pump on and repeat forever constantly. I plan on having 2 231 style float switches and an AR relay but i don't think this will work. Any ideas on how to accomplish this?
