Thanks for the help.
"Can you figure out the model number? Is it at least in sump or out of sump? Is it pump fed or direct fed by overflow?
- I looked it up. Its the CS 8-3+.
Here's a pic of it next to my older, smaller skimmer:
And here it is in the sump
Fed by two Sedra pumps.
"Sounds like your water level in the skimmer could be elevated. When you close the air valve is the water level where you expect it?"
- Thats what Ive been learning from another thread I have going on. But, to be honest the level in the sump really hasnt changed that much. During this summer, the level is much more varied, which isnt good to begin with. Im thinking maybe something's blocking the output?
To your other question, when I installed this (Jan) I closed the gate valve all the way and the water just shot out the top. So, the whole time I've had the gate valve opened all the way.
I've also just learned that my output maybe shouldn't be under water?? Aggh, it has been this whole time!! Maybe thats why my valve has had to be open all the way??
