Need a countdown controller for plug, that needs not button pushing!

[DeepWell]

Hi, I have a well that feeds water to the house. I want to put a countdown timer on the power outlet it plugs in to that will limit it to 5 minutes on only. This is ultimately a fail safe as it recently caused a flood in a million to one case of a bit of insulation lodging in the overflow pipe. So the long and short is as well as everything else we have, float switch, audible alarm etc, I really want a countdown timer that you don't have to push a button on every time you use it. Just want it so when we top it up by turning it on using the remote, arefter five minutes it will turn off. All the ones I have seen appear to need to be set manually with a button press to start it counting down, I want the power coming on to start it. Any thoughts? Thank you in advance, I massively appreciate it.

I think a timer such as this, will do what you want.
Unfortunately it's not plug-in.

Are you a designer, someone who can work with Arduino or the like, or just looking for a off the shelf solution ?

Regards, Dana.

There is this off the shelf device (not plug in as your request is more of a one off nature)

It would time out if supplied via a pulse input from the pump call circuit but would require additional circuitry to complete.
Equipment such as a contactor for the pump.

As above, I think the whole request would be out of your level of ability.

Thanks for this - it looked perfect. Have ordered one - thank you again for your time.

You can make a count down timer with a microcontroller+ 7 segment displays. You can use AC to DC adapter to power up your circuit.
