I am not sure the correct terms in explaining the parts but I will try my best… I’ve been trying to play with it the past two days and the same outcome happens to no avail. When I turn it on it sucks water up so fast that if I don’t unplug it in a few seconds it will over flow. Its a hang off the back skimmer if that helps. The little box...

I have had the back of the tank drilled near the bottom with 2 one and one half inch bulkheads. I have PVC running from both of those into one down pipe which runs into the sump.
