well i had drilled the pretzeled return for a non siphon effect but then i put the educators on there and i had to get rid of the holes so i changed positions of the 90's so the holes where blocked. i will test the tank to make sure there isnt to much being siphoned on power outages, but with the educator's you have to have equal pressure from the outlets or they wont work so im guessing that i cant have an anti siphon break????
anyone know??
