Tunze 9002 help
 

I am doing the mod to run the airline out of the top and I am using this valve that I had lying around the house. The top part twists to tighten or loosen. What's weird is when I tighten it up I am getting some bubbles making their way up that look sort of thick, but if I try to loosen it or even take it all the way out, I don't get anything. Which is weird, because if it is wide open it should be start being a wet foam into the cup, right? I'm wondering if this valve isn't the correct valve for what Im' trying to do. I know on the video he uses a gang valve that he cut to make smaller, but I'm assuming all the valve does it control how much air gets sucked into the skimmer, right? In other words, do you guys think this valve is my issue? I'm just not sure if there is something critical that the gang valves do that this one doesn't.

Thanks!

Maybe yours is lefty tighty and righty loosey. Instead of righty tighty and lefty loosey.

Hmmm...I don't think that's it. If I were to unscrew the screw all the way out water doesn't start filling the cup.
