O.K. I purchased a 10 foot long piece of tubing to hook to my water pump and tested it out on one of the farms I had to drain and it worked like a champ! I don't have a nearby drain so what I do is drain into a nearby bucket (10 gallon) and dump it down the tub drain. Question now is... can I just use the pump in the controller to drain all the farms since all the levels will drain to the same level right? Or do I have to drain out all the farms one by one. I figured that draining from the controller would be the best way. Please let me know what you think.
