I had the old style plunger valves on my pool and they worked ok til they got old and stuck when trying to move them up and down so replaced them with the newer style and air is coming in thru it now and the tank the holds the cartridge won't fill up with water and bubbles are coming thru the out take hose. The intake valve is making a groaning sound and I can't leave the pump on for one minute without the air building up in the filter housing. I checked the dark gray connections under the turn on and off caps and they are tight. There is a little nozzle behind the turnon/off cap. Does it do anything?
