lol. Too funny. They are only taught to offer these products without ever thinking if they really work.
I looked at my set up and I am sure we are all the same with the Highwalls because the tank is above the floor. My drain comes straight down thru the floor and then makes a 90 degree turn towards the blade valve exit.
If the drain is in fact on the bottom of the tank instead of the side discharge like the video, then we may have an easier time cleaning them out. I think the reason the tank in the video did not work well is because the flow was in the middle of the tank and not much of a current around that two lower corners. But if it is on the bottom with no lip to get caught on, then it should drain a bit better because the current should be all around the drain. Maybe like a sink it could even swirl if it is full.
My plan is to pick up one of these Camco wands that spin a jet around and hope to move the stuff into the hole. I hope it works.
