    In our UFH I have noticed that 2 actuators are in the wrong position. When the stat for a room is calling for heat 2 actuators open but 1 of them is to the wrong pipe so 2 need swapped over.
    Would they simply screw off or clip off?
    Is this something I could do myself or would I need to get plumber back.
    It is a Wavin UFH Sytem

    Hi there,

    I don't know how to remove these ones I'm afraid. The other type Wavin does is a "clip on" type and you have to press two tabs to remove it but I can't see it on these ones.
    Might be worth to check it with Wavin technical team.

    Actuators are only pushing the pin valves up and down so once you know how to remove them you can over on the manifold on your own.
    If you need to unplug them from wiring centre and you you don't feel confident perhaps you could get an electrician to do it. Usually there's 2 wires (L + N).

    Hope that helps.

    Thanks for the info re clipping - I turned one of them round and there was a clip at the back - pressed it firmly and it popped off handy enough. Easy enough - cheers.
