My pool has 2 skimmers and one I plug the kreepy into most of the time. I can also adjust flow between skimmers via jandy valve. My question is if I remove cleaner from skimmer can I just plug that skimmer with a plug and only use the other skimmer, for some reason my flow adjustment will not allow me to turn the flow completely off of the deep end skimmer. So I was contemplating blocking off that skimmer manually and maybe that would increase flow to the shallow end skimmer? Can this be done without permanent damage to something in the plumbing and will this really increase suction at my other skimmer?
