I am not sure on the time. Take a look and see I would imagine they have different sized ones which may last longer than others. We have not gone out and purchased ours yet. If you find one let us know im sure alot of people would be interest on how ya did. Good luckDoubleT said:thanks
iam going to get one. how long do they last
I think he forgot the hole to, BUT! When the power comes back on the siphon does not start right up so if your not home and the power goes out and then comes back on, the sump would flood the main tank. Its happened to me 3x so I went out and bought a $200 back up the most it last is up to 52 hrs. It also depends on what you have it plugged into.trreherd said:What? your sump should not be overflowing even when the power goes out. What part is overflowing into the sump? I will eliminate the overflow box(obiously) Im thinking you forgot to drill a whole in the return line for your wet dry. What might be happening is that when the power goes out,the water in the return ling gets pulled by gravity the opposite way and syphons the water from your tank to your sump. To fix this all you have to do is drill a 1/16th inch whole rite below the water line in your main tank so when the powergoes out,the the whole will break that suction therfore leaving your floors dry.

You are correct about having enough room in the sump to let out that last 1/2" water from the main tank through the wier, or overflow for those not familiar with the term. Many of us choose not to use a backflow as they add restriction. I prefer to have my pump run wide open. To compensate for not having a backflow, or checkvalve, I drill a 3/32" hole at the water line of my suction tube and my return line. As soon as I lose power my return line hole is exposed to air thus immediately breaking the siphon of the unexposed return.
