Ever since putting in an in-wall skimmer (I did hydrotools widemouth mod on intext 16x42). . I am noticing I frequently now have to bleed air out at my intex 2650 pump/sand filter. I do this by slightly unscrewing the lid for the strainer basket on the intex pump until it bleeds out then tighten it back. I am wondering if waves/splashing that goes through the skimmer introduces air. I never had the issue with the standard pool inlet or the above wall intext skimmer. I did put the door on the skimmer that floats the door up when not running but it still swings open and waves make it all the way through the skimmer. Any ideas, suggestions, or advice would be welcome.
