Hi All. This year when starting the the filter I'm noticing a leak between "to pool" elbow at the top of the filter, and the straight piece with the small piece jutting out. (See video). I don't even know how these two are connected. I tried turing the straight piece with a large wrench and it doesn't budge. Any help would be appreciated. Thanks!
