It didn't almost flood. I said I could see one comin'...meaning if I kept with the siphon overflows I envisioned a flood in the future.
Started with two overflow boxes, one U-tube in each. Did a test to see what would happen if one U-tube lost siphon. Test failed. The one siphon left couldn't keep up with the return. So, I doubled up the U-tubes. Two in each box. But then there was too much distribution and one U-tube would lose siphon over a long period of time, leaving only three doing the job. One day I noticed salt creep on the plumbing to the sump. So I shut the pumping down to silicone the plumbing joints. My sump slooooooowly continued to fill with water. Turned out water was being siphoned out into the sump through the powerhead's airline tubings. Oh ya? So how do I stop this? Check valves in the airline tubing. So I went out and bought a bunch of check valves. But I never installed them. I decided @*^%$# this. Shut the sump down, went back to a canister filter and pressed on as before until I could afford a drilled tank.
I should qualify this by saying that part of my decision was the fact that I worked away from home for long periods around that time. But still, wether one is working 500 miles away or 5 blocks away, a flood is a flood. You just find out about it sooner if you are 5 blocks away. JMHO.
Cheers,
