...I only wish I did. It was entertaining to see that thread again. Especially where I said something like "...it violates one of the laws of Thermodynamics but I don't remember which one". The translation to that is "I was wrong" I still think about the concept when looking at pumps.
drill a small hole an inch or so below the waterline in your syphon as well as yer pump line and this will not be a problem...
my syphon AND overlow can clog.. my pump will run itself dry, overheat and shut off and the water will still be 1/2 an inch from the top (about 5/7 gallons)
my pump can die and the water in my tank will drop a lil over an inch... the waterline in my sump will be about an inch form the top (20g long.. so however many gallons thats worth)
