I have two skimmers, one on the west side and one on the east side of the pool. Each of them have two holes at the bottom, but the skimmer on the east side has the 2nd port plugged off with some kind of cap. The west skimmer's 2nd port is not plugged off, but doesn't seem to serve any function as I cannot establish any kind of circulation through it and it has some debris in it. I was thinking maybe it has something to do with the drain at the bottom of the pool, since I cannot figure out for the life of me how to establish circulation through that thing.
