Overflow box not siphoning

I just think that the more gizmos and gadgets one has, the more things they have that could malfunction and go wrong. The external system I had, I decided, was getting too complicated with to many "parts" and thus an increased potential for one of those parts to malfunction. The simpler, the better. IMHO.

For the cost of the external box(es), the powerheads, the check valves, the switch, etc. ...why not just pay a little extra and get a drilled tank and buy some peace of mind at the same time?

BTW...I disagree with there being such a thing as a flood proof external siphon overflow system. Sorry.
