1.) What if the return pump stops and the overflow keeps going? Also if the pump stops it creats a shipon wich will fill up the sump even more.
Iam thinking of cutting my "u" tubes shorter to where once the water level gets so low they will stop. What do u think?
I really need your help:help:
Thanks

buy a check valve for the return line. This will only allow water to flow one way.

Check valves are known to fail. For a sure fire fail-safe, drill a hole in your return line, just below the water line of the tank. That way, if they start to back siphon, as soon as it gets down to the hole it stops.
The overflow box, I have mine set high in the water so the water level of the tank is pretty high. It's about on par with the hole I drilled in my return line.
If power fails my sump can handle the amount of water that gets siphoned. I've tested it :)
I employed all this because last week I had a flood when I made the stupid mistake of plugging my return pump into a timed powerbar temporarily....needless to say when the timer went off, and I wasn't home....flood. :mad:

if your return pump stops water will not go in to your tank and will not fill the overflow as for the return line do drill a hole in it and as soon as the pump stops the hole will suck air and lose siphon the only thing that can happen after that is the pump starts back up and your overflow has lost its siphon and pumps all the water in your sump in to your tank and over filles that.

I have mine above the water line, but i used a saw and angled it down, so the water coming out will spray into the bottom of the tank. Just put you a hole right below the water line in your main tank. When your pump shuts off, it will suck air and break the siphion (sp). Make sure it does not get clogged up, or it will not work. Now, if you will excues me, i am gone to clean mine out. it looks a little clogged. :nervous:
