I have a inground concrete pool in Florida, just replaced filter to a hayward 1200 and pump is strong, I had air bubbles in the pump basket before the filter switch over and they are still present, which leads me to believe there is an leak on the suction side, the pool has the bottom drain that goes to skimmer first then only one line form the 2 in the skimmer, actually suck back to the pump........PSI is like 7 and I can continuly open that air valve to let air escape and fill the filter. water circulation is poor, there are 3 return lines, all small and only one has significant flow to circ the water......pool had some debris in the bottom mostly leaves and such, we did vac them out.....how can I first make sure the lines are not clogged thus reducing suction, and second cure the air bubbbles in the basket ? I do have one of those black rubber drail unclog deals that u attach the garden hose to blast a clog away........if I close off the return the psi will increase and filter the water more ..correct, or is the problem not enough water suction thru the pump ??...thanks

Hello, It is Saturday and everyone is closed locally, so hopefully someone can help me here. Our hot tub pump will not start. It just humms. I can take off the end hose and get the pump spinning with my finger, and it runs fine. But then, when up to temperature and it turns off, it will not start again on it's own. Only if I spin the impellers with my finger. Is it dirty, need something fixed, replaced, ??? The pump is 6 years old, is a Waterway Super-Flow model PF-15-2N11CD. Thanks a lot for your advice, folks!
