I like the extra capacity because my ATO can screw up and empty it's entire contents into the sump and at the same time the power can go off and my DT can overflow into the sump and I'll still not have water end up on my floor. The new house has a finished basement and the wife would never forgive me if I flooded the basement (again).

That's good! Yeah, I like the look of the black silicone over the clear. What kind of ATO are you using?
