    Hi all,
    I've just been doing a bit of work in the bathroom and have replaced the thermostatic shower bar. All I did was remove the old and connect the new one, exactly the same as the old one.

    The shower works, however the controls seem to work in reverse. When I turn the knob to go above 38C it gets colder and when I turn the knob for colder it gets hotter. The switch to turn it on/off also seems to be working backwards as well.

    The new one is a Premier vbs001 - like this one: http://www.victorianplumbing.co.uk/...ic-Bar-Valve-Bottom-Outlet-Chrome-VBS001.aspx

    Any suggestions on what to do/what I should have done?

    I didn't realise before, but as I went to take pics I noticed the old one worked the opposite way round to the new one ...


    Is it possible for me to get the new one to work the way it should do or do I need to return it for one that works the same as the old one?

    The on/off would work the way it's supposed to as that's just an on/off tap, the hot/cold temp thermostat though needs the hot and cold feed pipes to be entering into the bar on the correct sides. The only cause for the symptoms you describe IMO, are that the pipes are not the correct way round.
    Not every bar mixer is the same, they can have the hot and cold feeds on different sides.

    I did contemplate that, but then I wouldn't be able to see the controls and the hose would be going the wrong way.

    Feed is hot left, cold right, which I assumed to be standard.

    Looking at different valves, could anyone suggest one that should work the correct way round? or would I be better off playing with the pipework a bit and switching the hot & cold around? Changing the feed pipe's shouldn't be too difficult, they're just tee'd off the bath feed and exposed under the bath.

    I think you answered your own question there. If you can swap the pipework then it's no brainer IMO

    Thanks for the help guys, feeds switched over and it's no controllable as it should be.
