For the filter socks on the drain piping, I used a hacksaw an cut about 1/4" off of an appropriately sized PVC slip coupling and slid it up the pipe where I wanted it and secured it with PVC. It's kind of ghetto, but my 8 y.o. daughter volunteered a hair elastic to go around the 2" drain pipe and hold the sock in place. She was all proud of herself so it's still there.
