when i hook up my vaccuum to the skimmer i get air bubbels comming out of one of my jets and some air bubbles out of the spa return. there is bubbels in my see through cap on my pump also as well as my cartridge filter unit. as soon as i disconnect the hose from the skimmer all bubbles go away and a purge the filter unit and i ahve no more air bubbles anywhere. and i dont loose prime on pump or filter ever.
so.......could these bubbles be comming from my spa valve where it intakes air for the spa???? or should i be concerned and look elsewhere? no leaks on pump slab.
please help thanks!!! todd
