There appears to be a small leak where the PVC connecting my main pump and filter exits the pump.
In this slightly crappy pic, the piping in question is just to the left of the filter, attached to the pump on the top.
Is this just a threaded connection? Is there a gasket, or just thread tape? I haven't investigated closer because I'm in the middle of shocking the pool, but when I get my chemistry closer, I'm going to try to fix the issue.
