I have a 2.5 gallon cat litter jug I fill and set it on the ground. The top of the jug is about 2 ft below the AF connection on the TT. It takes about 30-45 seconds til I hear the pump prime then another 30-45 seconds for the AF to come out the farthest opening which is a low point drain. I had to cycle the pump on and off once or twice when I winterized this past October, I think the pump was stuck.
