New pool owner here. Was attempting my first cleaning on the cartridge filters and ran into a snag....
I opened the top bleeder valve and then the bottom drain (which has a hose valve on it). When I open the bottom drain on the filter housing it actually sucks air in! There seems to be slight suction pressure and when I crack the bottom valve air sucks in and I can hear the large air bubbles entering the filter housing. Considering water was supposed to empty from the filter I figured something is wrong.....
I havnt left it cracked open for more than a few seconds at a time, maybe 20 seconds max in total as I was thinking around. Any thoughts on this and how I should proceed?
