I've been using it for about 6 months and it's been an absolute nightmare. I much preferred my simple not so safe single full siphon overflow I used to have.
There's been tons of problems before I got it working properly. Currently I have one left: I can't ''start'' the overflow without having to play with the main valve a bit. Whenever I turn the return pump back on, all I get is a pathetic bit of water and mostly air going through the main drain. Then the secondary drain comes into play, which flushes the entire overflow chamber. This process keeps repeating itself without my interference.
I have both the primary and secondary drain coming into the sump area about 2'' below surface. The downward facing elbow inlets are about 4'' in height apart from each other. Drilled a small hole in the secondary drain and fitted a piece of airline tubing. When everything's tuned properly it just works without problems. Completely silent. It's just starting it back up without opening and closing the valve is simply impossible.
Any ideas what's going on here? See video below what happens when I turn the return pump back on. I have the main drain above the surface here, just to see if that would've made a difference.
