Right I've been at this for weeks now after speaking to lots of people but I still can't get it to work.
I've got a dual action float, which has 3 core cable
Brown
Blue
Black
I've been told that black should blanked.
Blue float to no1 in valve
Blue mains to no2 in valve
Brown mains to brown float
The idea is that I can leave the tap on when I extract water from my static tank the float drops and fills the tank once the float reaches the top it switches the water and waste off.
Does anyone know how to correctly wire this up,?its driving me mad as I've just wasted £120:00 on something that I can't use.

I presume you have a Clarke Float switch. I also presume that you are using a 230v normally closed solenoid valve.

If you are then the float valve has 2 wires you need to connect up; the brown and the blue.  The black isn't connected as you say.

If you make the brown the positive from the 3 pin plug, then the blue becomes the positive to the solenoid valve. The neutral from the solenoid valve then goes to the neutral on your plug. On my solenoid valve the red wire was the positive and the black wire the neutral. The earth on the solenoid valve went to the earth on the plug.

Please only use 230 volt with a rcd if you haven't one in the consumer unit already.

If this is a low voltage system then the brown wire you have made positive comes from your power supply on the reduced voltage side.
