I installed my liquidator and it filled right up no problem. I can easily max out the flow meter wide open. Anyway, once I had it dialed down to about 3, I noticed some tiny bubbles in the clear hose, starting at the flow control valve. The bubbles slowly fill the flow meter with air but it seems to stop around the "3" mark and then the bubbles are mostly going down the line toward the pump. Many of the bubbles stick to the hoses. I can't detect any air in the pump basket so maybe the leak is too small for the pump to lose prime or anything like that. Still this concerns me.
Anyway, I have tried a lot of things after doing a search on the forums and google. I even switched out the upgraded 3/8 control valve with the smaller grey one and it still leaked air in. I also bought a tube of pool gel and lubed the hoses and connections and that didnt work either. Then I noticed if I turned on my main drains, it stopped pulling in air and seemed to go away. So now I am thinking that my pump is pulling too hard and creating the air leak. Only problem is if I open the main drains, then my pool cleaner (TPC 2x) RPM will be below specs and moving too slowly so that idea isnt really going to work.
I also noticed a ton of tiny bubbles inside the LQ tank and around the float valves. I started to wonder if they were being sucked in but then I thought if that were the case, then wouldnt there also be bubbles on the hose going from the LQ to the flow control valve? The bubbles only start at the hose connection after the flow valve so that is where I have decided my leak is from. Weird that I have tried both flow control valves and they both leak? Is it possible the suction is too strong and they are leaking at a place other than the hose connections, like maybe in the valve lever linkage or something?
Any other ideas? I thought I read somewhere about the floats potentially leaking in air but I am ruling that out since there are no bubbles in the line from the liquidator.
