    Hi
    I am looking for a way to add a mechanical float switch to my RO tank, the float awitch should shut off the incoming supply to the RO unit and not the filtered water.
    Anyone know of an inline float switch, or how to do this.
    Thanks.

    @Penny, you don't shut off the supply to to your RO, the pieces you need will be:

    1) Float switch to turn off water RO when your tank is full Stops RO production when you tank is full
    2) RO Auto shut off value - Shuts off water running out at waste
    2) In the line of your incoming supply you will install a pressure reducing value (PRV) Ensures no pressure build up inside RO unit and limits the feed tap water supply to 40psi

    This will result in a fully automated top of system.

    Give us a shout if you need more help.

    @Andre@ReefAquatics

    Where do you install the RO shut off valve and why do you need to reduce the pressure on the incoming side?

    Please can you PM me a price on both :)

    Basically this clever piece of kit shuts off water to your membrane.

    @ScottK , see red answers above.

    Here is how to connect the the Auto Shut off Valve, (courtesy from Google so I did not have to sketch it):

    Also see out RO Auto Shut Off Conversion Kits here:

    That Google Diagram does not seem to be correct! Thats not the way the flow thru valve is!!

    The PIC of the installation seems fine!!
