Shut off valve

[gangito]

Where can I find a 1 1/4" electrical emergency shut off valve
for the pipe coming from tank goin to the sump?
So my sump won't over flow if power goes out?
Please help!!!

Not sure, but the level in your sump should be at an appropriate height to have space to take whatever water backflows into your sump whenever you shut off your pump or have a power failure. Also, you drain pipes should have an "anti-siphon" in place. This can be achieved by simple drilling a hole in your pipe just below the water line.

As noted above. There shouldn't be a need for a cut off. You sump should be designed such that it will hold as much water as your tank will "spill" in the event of loss of power.

I think he is thinking of a check valve.

USplastics has some. be sure to get the swing flapper type valve and not a piston or spring one.

I have a spare 1.5" one. If you want it shoot me a PM

Also mount it AS HIGH AS POSSIBLE!
Back pressure builds up from the sump pump and they rattle like heck if it's plumbed to low...

That won't work since it's the drain pipe from the tank to the sump (unless op mistyped).

There are electrical valves that'll do what you want, but it's a terrible idea. If something happens to that valve's controller or circuit, causing the valve to prematurely close, the tank will overflow. As others have said, you need to size your sump appropriately.

Do NOT put a check valve on your drain. Even the good ones will fail at some point.
You really need to just get a bigger sump if it can't accommodate the power going out... Or you doing a water change.
