Hi! I just replaced the shell of my backup valve because it cracked in half. I am using tehgearbox form he original one which seemed to be OK. The polaris is moving around the pool fine but I thought there was supposed to be a steady trickle of water that comes out of the backup valve the whole time. Am I remembering that incorrectly? I dont see that happening. I also havent seen the burst of water but then again it has not been stuck as far as I have seen. Can anyone advise? Is there supposed to be a steady stream of water coming out? Thanks!
