Some sort of float operated switch needed.

It doesn't need to go into the pump.

Even easier then. I saw the beginning of the thread but then it went awry so I just chimed in!

We used a set up from RS a while ago, sorry I can't find the details now, it was basically two stainless steel rods, a control box , you adjust the length of each, to read the fluid level, low voltage wired via a relay to start the pump. No moving parts so quite relyable.Deke

Thanks Deke..... but not actually needed to work the pump...

Just an alarm when the existing pump fails so water level gets too high!



ps

I laddered the blue stockings today.....

You can use that device for anything really, I 'm sure it had some clean contacts you could use for a warning device .

Go for tights in this weather , much warmer.

Who remembers when there was a cold snap quite a few years ago. There was a shortage of tights due to lorry drivers wearing them under there trousers. Another piece of useless information.

Buy a diecast limit swich fit it above the level of the cess pit, use a ball cock float attached to some fishing line.

You can adjust and test without going into or opening pit also easy to pull bollcock float out to clean if required.

Any !/2 tidy wholesalers will have limit switches in stock cost Zilch but easy to maintain and test.
