I've just got a new storage tank, which has thicker Walls than my old tank, which means the the old float valve with the micro switch attached won't fit. So I was wondering what setup others use to turn off the water supply and booster pump together.
Thanks

use one of these and wire it into your pump

Thanks for the link, but I need to stop the pump & the water supply together, and this won't do that, or am I being thick ??

You suspend the float switch from the top of the tank, when the water reaches it the float switch will then float which will turn the pump off and then stop the tank filling
-
the water still keeps coming after the pump has been turned off just through the water pressure ???

You also need to connect the float switch to a normally off 1/2" 230v solenoid valve. The float valve will switch off both the pump and the water flow from mains at the same time as they will be wired together.
Example;

This type of valve is like a tap. Put current to it and it opens and lets the water flow. Remove the current and is automatically closes the valve so no water flows. If you have a power failure everything will switch off and once power is restored, your R/O will continue to process water - you won't even know its happened.
Some have adapted a washing machine shutoff valve which is a lot cheaper. My concern here would be an electrical safety issue which would need to be considered and the valve would need to be supported.
