Thoughts on this idea? I am thinking of drilling a small hole just under the top of my sump to attach a bulkhead and pipe or tubing that would run into a collection area. The idea is that, in the event of what would normally be an overflow of the sump (e.g., ATO stuck on), the excess water would flow through the tube into the collection area rather than randomly over the sides of the sump. Not only would it avoid messes, but a leak detector in the collection area could then trigger shutdown of the ATO and whatever else might cause the overflow. My collection area happens to be a gutter behind the tank, fwiw.
