New pool owner, not a new pool. I have 2 returns that happen to be the ones right under the skimmers that don't flow in my pool, the eyeballs look great, nothing weird. All other returns work as well as my polaris line. I do not have float diverters in the skimmers if that has anything to do with it. Any ideas? I am going to clean the filter in the next couple of weekends to see if pressure has anything to do with it. Thanks!
