Why do you have shut offs on all your outlets? I would have 2 with no valve and 1 slightly lower (with no Durso and low enough to not cause a vortex) in the over flow with a valve to adjust the level. The 2 higher outlets are only in case the one with the valve clogs. Use all slip inside the overflow and seal with a couple of wraps of Teflon tape only.
