    Hi,
    Having run 22mm pipe as stated from the shower/bath diverter to the bath and shower. The 22mm for the shower goes up to the loft and drops down from the ceiling. Now the shower head and arm has turned out it appears that the connection from the shower arm is 1/2" male. So I am after either a solder fitting or compression fitting that goes from 22mm to 1/2" female, I dont seem to be able to find one easily.

    Also there are no fixing holes for the shower arm so is this simply supported by the pipework? The showerhead is a 6"square.

    Many thanks
    Olly

    Olly,

    If I have understood you correctly I would simply reduce the 22mm to 15mm then connect the 15mm to a Backplate elbow which would have the 1/2" female you are after,

    I trust you have access to do this and also to insert a dwang to screw the backplate to. This will support the shower head as well.

    If you are tiling after make sure you get your depth right for the backplate so the arm screws in and then leaves enough space for the depth of tiles.
    Good Luck.

    NOt quite able to use the elbow as the shower arm (Which will drop from the ceiling) only has a limited space behind to place an elbow behind would mean it doesnt sit flush.

    Can you not then use a straight female connector instead of the backplate? You will then need to support the pipe some way either with banding or clips.
    I doubt you will get a fitting that goes straight from 22mm to 1/2" female. Suggest Yorki 22-15 reducer then straight female.

    the arm does need supporting properly...(is it coming out the wall or the ceiling/) You can solder 22x15 reducer to the end of the pipe and then fit a 1/2"FI x 15mm adapter or wallplate elbow on the end.

    Its coming out of the ceiling. At moment have 22mm in loft space and coming through ceiling. Will have to change to 15mm in loft and then use a 15mm to 1/2" coupler. Will the shower head be ok if I support the pipe using pipe clips (As I have done)

    Probably if it's just supporting it's own weight and so long as it's not an adjustable head people will be pulling on...just use common sense really.

    Its does move what is the correct way to support something like this they are quite common having a shower drop from the ceiling with a small shower arm. Do the shower arms usually come with fixing screws to attach to the ceiling?

    I often use 1/2" threaded brass barrel clamped with 1/2" backnuts thru some substantial ply. It's not unusual for there to be no mountings provided!

    I installed a square fixed head shower recently which came through the ceiling,with a solid chrome brass extension which the shower head screwed to.Is the thread on the extension or shower head stripped.

    But you probably wont find one in stock anywhere so thats why I make one up from barrel and backnuts.

    Not sure I know what you mean by stripped thread. Its not rough like some radiator valves if thats what you mean. What CL is what im after bit pricey for bit of metal, may make one up as well.
