We got an all glass megaflow sump today, and the flex hose that came with it, the one that attachs to the overflow drain into the sump is too long. Or is supposed to be long and made to loop around to attach to the sump? We've got a loop in it now, and the water draining into the sump gurgles really bad at times. Seems to me that water would have a hard time running uphill, (through this loop) and is causing the gurgle, burping, flushing sounds. The water in the overflow box will rise almost to the top of the standpipe, then like it's being flushed, it falls back down. I've got a mag 9.5 pump, and I have it cut down to almost halfway. My question is, is the hose supposed to be long and made to loop around? Or, do you cut it to fit more in a straight line?
