    Hi everyone - I'm new to the forum but hoping someone can help with this one.

    The Shower in question is a Shower Stream manufactured by Meynell Valves Ltd and is the bath tap mixer type.

    We've had the shower about 15 years with no trouble but it gradually needed the dial turning further and further to get hot water - now there is no hot water at all coming through the shower. The flow of hot water at the tap is fine so I know it's not the filter on the inlet. There has been no change to the hot and cold feeds (gravity fed hot, mains cold with flow restrictor)

    I've had the shower in pieces today to see if I could see what the problem was - there is no sign of anything being broken - all washers seem OK and I can't see that anything is seized up - it was all pretty clean but I've cleaned it up anyway. I've adjusted the temperature screw all the way in and out with no effect. I'm absolutely baffled as to what the problem is. The instruction manual is of no use as it only really has installation instructions.

    Would anybody have any experience with this unit and any helpful suggestions, and/or an exploded diagram of the workings of the shower. I've searched on the internet without success.

    If it's any help, the details on the underside of the shower tap are:-

    i took one out last week, the tennant could only get a warm shower by running the basin or bath tap at same time! didnt try to fix it but replaced it with a mira extra shower / filler which looks very similar.

    Holty - Planetthanet - thanks for the replies.

    Holty - If i turn the cold off, there's nothing coming through from the hot at all - the mechanism inside obviously isn't letting any hot through at all.

    Planetthanet - thanks for the link - very useful - didn't hold up much hope of an exploded diagram so that will help enormously. I'll strip it right down again tomorrow and let you know how I get on.

    Thanks again

    Hi, hope someone can help, I realise this is an old thread... a google search brought me here.

    The shower part has become more and more difficult to turn off recently and I now have a constant dribble... I have taken off the plastic cap but can't see how to get the rest of it off to change the washer.

    Thanks in advance...
    Colin.
