Ok, have a problem now.
I know I can drill a hole on the Utube, so when power is out, my sump won't flood, but today, the Utube suddenly stop suckin water (no idea what had happened), I m glad I was near by so I stop the return pump.


what should I do to prevent my DT to flood?

lower my DT water top line, or
suck some water out from the return section, but if I do either of that, the pump will burn out if my overflow stop working.

need help >o<
I m afriad either of that will happen again when I m not around ToT

The siphon break hole should be in the output in the tank just above the water line with the pump off. IMO Your output tube inside the overflow box should be higher than the partition (can't tell with the foam). If you put a hole in the "u" tube you'll need to connect it to a power head venturi.

alrite, I will do more research on it, then see if I can fix it tmr.
Thanks ^^

I wouldn't put a hole in the siphon tube for the overflow (if that's what your talking about lol) its best to stick an airline into it and prime it, and once its primed the flow of the pump should keep bubbles from accumulating. At least that's how it's working out in mine.

I've turned off my tank nightly for a few weeks now and it hasn't lost a siphon once (quite happy with the Eshopps box)

Are you using it like the photo above?

I just noticed that your hose from the overflow is at the bottom of the sump. Try to keep it off the bottom for better flow.

Which photo? xD

I have mine set up as level as possible, i think that's one of the key's to it. As long as it's level and the U tube is always submerged, the siphon will restart. The only difference between my set up and the one here is that I have rigid pipe (doesn't matter when regarding siphon failure) and instead of the foam pre filter I just have a longer stand pipe. (also doesn't matter in this case)

IMO the longer stand pipe is the key.
