Thank you for the information! I purchased the pump you linked to. I have it set up and the suction is great! I think it's going to be a good investment. The problem i am having now is with vacuuming. I already had some issues with loss of suction with my old pump when the debris bag had some dirt/sediment and also the intake valve would get clogged but this happens on filter setting also. I cannot keep suction long enough to vacuum. I wondered if I could hook up the hose to the inlet valve as I think part of my trouble might be the vacuum skimmer attachments. Has anyone had this trouble and if so what worked for you?
