overflow protection

[thepresence]

Can someone point me to some posts about prevent a sump from overflowing if the pump breaks down? Or maybe someone can give me some ideas on how to do it? Thanks.

maybe you could post pics of your setup.. then i and im sure others could tell you what to do from there

if you have a syphon in the tank.. your sump will overflow...

if you have an overflow in the tank... your sump will not overflow.. as long as you have a hole in the pump line just below the surface of the water to prevent backflow when the power cuts out/pump dies


all of this goes out the window if you overfill your sump..

what do you think might cause this too happen it is unlikely too happen

I use an EShopps overflow which will kill the syphon if power goes out. It will restart itself when the pump comes back on. If your return is positioned well below the water line it will siphon until the water line is below the return which may overflow your sump. I use a check valve to prevent this.

They siphon never stops, the flow of water is just prevented as the water level drops.

Check valves are sketchy to me. I know they work well for others, but I'm just not sure I would trust them to prevent water from backflowing. The are a good precaution, but I would rely on them 100%.

That's what I meant.

I have always used em and have been through a few power outages w/ no flooding. I also shut off filters all the time for feeding and wc (of course) and they've never failed.

I agree with Pharaoh, check valves fail. You should be able to set a system up where a check valve is not necessary. Run your sumps at the lowest level possible so you have the extra capacity when there is a power outage. Test by powering down the system, let everything drain into the sump and then fill the sump to capacity. Turn the pumps back on and when everything stabilizes you will have the max water level in your sump.
