Special Sump Pump


Hi,

I am trying to find a sump pump that will stop water discharge when it gets to a pre-adjusted level in a tank. It would be the inverse of a toilet one that stops the intake when the level goes up.

My system will discharge water from a pipe out of the bottom of a tank, and I need it to stop discharging the water when the level has gotten to an adjusted low. Then, the water will be re-inserted in the tank through the top, and when the level is back up, the sump pump should start letting the water out again, through the pipe at the bottom of the tank.

Does such sump pump exist? What is the name of it? How can I build one?
Please help. Thank you.

Is this really a sump pump you are talking about? Usually a sump pump for ground water has a check valve above the prevent a back flow into the sump pit.

Could you possibly have a sump for laundry tubs or similar?

Why does the pump need to be outside the tank and not inside of it?
Without a picture of the tank it's going to be just guesses.
What you need if you have to have the pump outside the tank is a float switch inside that makes contact then turns the pump on.
There's hundreds of differant switches that might work, here's a few.

The pump has to be inside the tank. It will pump water out, through a pipe at the bottom of the tank. When the water gets to a predetermined level, the flow has to stop, so the tank does not empty all the way.

Then the water will come back to the tank to the refill level, and when it does, the floating cup has to start the flow out again, and the cycle repeats.

It is the inverse procedure of a toilet. The toilet stops the water flow with the floating cup, when it reaches a certain level.

I need the floating cup to mechanically, not electronically, not electrically, mechanically, let the water out, when the cup reaches the refill level.

Did I make myself clearer this time?

Are you set on electronically?
It can be done with float switches
How big is the tank?

I know it can be done electronically, I did it many years ago, back in 1985. I need to do it mechanically. The water goes out by pressure, because the pipe at the bottom of the tank makes the flow.

You can use a combination of these to set your hi/low levels. But something tells me it won't work for you?

No, it won't. I'm trying to not use electricity, the flow has to be "powered" by the water pressure. Water from the bottom pipe flows out by pressure. When it reaches a predetermined low level, the flow out has to stop.

Water returning to the tank, comes by gravity. When the "normal" level is reached again, that's where I need the flow to start going out again.

Not a conventional application, but something has to be out there that I can use, otherwise, I'm going to have to design it myself.

Thanks for your help. Let's keep on looking.

You have to have "a little bit more creativity" than that, just a little bit.

Creativity ? I am not the one on a web site trying to come up with some cockamamie contraption, funny thing is I know what you looking for, itís called among other names a counter shank swing valve W/adjustable float used in some sumps that filter and recycle water, like in automated car wash. Keeps tanks from going dry. Good luck finding one. I thought bedrock plumbing was pretty funning.
