Anyone tried adapting dishwaher drain pumps for aquaponics? I can get then surplus for $20 each and they look to be perfect, assuming I can fab up a water tight housing for the motor. Specs are 120VAC 140 watts. 14' shutoff head, 7.5 GPM at 7', runout flow 10 GPM. Hosebarb connections 1.5" in, 1 3/16" out. Rated for continous duty, but they are built to cycle too, being for a dishwasher.
