If you can't rely on them, what's the point???

Do your returns have siphon break holes in them?

No the don't. The way that the returns are set up, I don't think they would help. They bulkheads are about an inch below the water level. There wouldn't be a siphon to break.

Two of them exhaust straight out from the bulkhead, one has an adjustable arm on it to direct flow some more. I suppose I could use pvc or lockline and bring it up over the waterline and then down again and then drill siphon breaks...
