I have had a problem for several years. The port on the pool wall where the Polaris plugs in shoots debris back into the pool. I have given up and just kept the Polaris plugged all the time. When it is unplugged you can see small partials coming back into the pool. There is no sand in it so I don't think it is a lateral. I have had an ongoing problem with air in the pump basket too. Wondering if the two are connected. I don't see anything coming out of the other jets in the pool though...only the Polaris port. I have to clean the screen inside the Polaris at least every day and sometimes more. I thought I would try to address it early this season....any thoughts greatly appreciated.

Our equipment is 15 now. I have replaced the multi port and some of the o rings and some of the piping and sand over time.
