The only thing that would make me nervous is the unglued elbow and standpipe[
You and me both, sparkie.
TJ, I had a similar design on a larger scale with nearly disastrous results. I wasn't even intending to have an unsealed pipe, pond guy missed one seal. As the wall settled, it spread a bit laterally, putting pressure on the base of the standpipe, and eventually pushed it off the drain pipe. Ever try to push a telephone pole into a 12" drainpipe against a 15' head with a tractor in 34 degree water? I'm here to tell you it can be done-but I wouldn't want to do it again!!
