very compact sump pump needed
 

I need a small sump pump to drop into a tight sump in the yard. The previous owner told me he put the sump in to keep the water down during snow melt season. Its a very small sump. Maybe 2 feet deep, 8" inside diameter. At the top it necks a little, I don't think anything bigger than 7" would go in there.

Any recommendations for something I could use for a month or two? I looked for sump pumps but haven't found anything small enough to fit in there. I could put some kind of aquarium pump in there but I don't think anything small enough to fit will have enough juice to lift water out of the pit. Plus i would then need a way to control it.

Are there any sump pumps small enough in the world? Any suggestions on where to shop?

Here ya go, a pond pump - dimensions are right and can pump to over 5 feet

However... don't think ti is what you want, unless you want to manually control when the pump pumps. I'd also be wary of picking stuff up in the intake...

There is always one out there. How much water do you need to move? 115VAC? how high do you need to lift it? Does it need a float switch to run automatically? Lowes actually has a decent selection. If not what you want, check McMaster Carr.

Simer makes a complete line of sump pumps. Very reliable. I know Menards carries them..not sure about Home Depot.

A bilge pump bailed me out more than once.

yes, needs a float switch. 115 ac preferred. unknown how much water to expect. Cant be loads...

the sump is about 2 feet deep. I just need to get it to the surface and then ten feet to the top of a slope. Then it will be gone.

This should work.

You need a sewage ejection pump unless there is some kind of filter before the sump. Go big now or go big later, but you will go big.

Here is your float switch:

Assuming you will be running 110v out to a small sump pump, this switch has a piggy back plug which you can use in conjunction with the plug on your pump, in order to control when it turns on and off - according to the float which you will have to tether inside your sump somehow.

A cheap pool drain pump.
Then when the frost is out of the ground dig in a proper sump pit below the frost line, so the pump doesn't freeze and install a good sump pump. Then you don't have to fork around with it every spring.
