I have two skimmer boxes and two holes in each skimmer.
The back holes have suction when the pumping is running.
Then there are holes in front of each back hole that appear to go about 8-10 inches down into nothing, capped or just never opened??
There is a peice of hard plastic that rotates 360 degress to cover one hole at a time.
I was told that I should use the flap to cover the suction hole on the far skimmer basket about 80 degrees when I do my manuel vaccuming.
Is this the only time I should mess with this flap?
Why are there two holes?
Is there anything else I need to know?
Will batman get there in time?
