  2. Ista Auto Top Off Float Valve
    Ista Auto Top Off Float Valve
    £7.99

    Ista Auto Top Off Valve acts as a ballcock device that cuts the water flow off when the water in a container fills to a point that the float valve is raised.

    These are incredibly handy with auto top off units (ATO’s) and when producing purified water such as Reverse Osmosis (RO).  

    The fitting these come with is a ¼” John Guest (push fit) connection which easily connects the standard ¼” RO / High Pressure tubing.

     

    The Ista Float Valve can be installed via a drilled hole in the container or via the hang-on bracket supplied. The float valves themselves are adjustable making them adaptable for most applications.
