Sorry to hear that.
Your far from the first person to have that problem with CPR overflows.
I had a snail plug my overflow one time but I was about ten feet away when I heard water hit the floor so I got by with about five gallons on the new carpet and pad.
The hardest part was getting the carpet dried under the stand.
Oh and the smell even after cleaning the carpet drove me crazy.

You have more bad luck than anyone I've ever met!
I just about had the same thing happen this week as well. One of my u tubes lost siphon luckily there wasn't quite enough water in the sump to overflow the tank and the other u-tube was handling a little bit of the water. But it was REALLY FULL when I got home from work!

Slave to the reef!
i have had good luck using them with freshwater, actually never once has the siphon broke. I think it has something to with the air bubbles getting trapped in the overflow and causing the siphon to break. I think im gonna get an aqualifter pump for it....hell while im at it i think i might order a reefkeeper 2 as well.

The aqualifter is definitely worth it. Made do for a year without one, contantly had to suck out the air bubbles in my overflow, overflowed once, got the aqualifter when I moved in august and haven't even had to look at the overflow since.
I have mine hooked directly to my skimmer pump. I have to do 4 month cleanings just to keep the peace. But one huge problem I almost ran into was the suction hose from the overflow box to the pump in the sump blocked due to coraline alge growth in the tube that was exposed at the top of the tank. Something to consider.

Oh yeah. I also sanded and krylon'd my overflow to keep algae from plugging it. That was a major problem in the past.

For the record I use a CPR overflow (with Aqualifter) and we use one at my office (without an aqualifter) and neither has ever failed.
I do think the pump mandatory due to the nature of the design. The CPR's don't have the same flow velocity as the U-Tube overflows so the bubbles tend to get trapped. If enough bubbles build up, the siphon breaks. This is why you need the pump there.
Alternatively, you can run an airline from your CPR to a powerhead in your sump (note: NOT in the display tank). This should serve the same purpose as the aqualifter.
I like my CPR a lot, the "U-Tube" overflow it replaced was a total eye sore.
