    Hi,

    Im replacing a microbore system with 15mm and have hit a problem with one rad.

    Its up against a wall that the joists run parallel to and the drop pipes from the rad hit it. In the past they have notched the joist and bent the microbore to fit. Im not sure how to approach replacing the microbore for this rad.

    On others im dropping under the floor in chrome plated copper and then running speedfit pipe and fittings under the floor.

    I cant move the radiator out as its 50mm and will look daft.

    My best thinking is to notch the joist more and use a solder fitting (something small?) then a copper stub and speedfit from there?

    Advice appreciated

    Graeme

    yes, tightest way is to use a solder fitting and will allow you the least amount of modification to the joist ...... Oh and I'd get the PTFE tape off of those valve threads, it just isn't needed, it doesn't do anything.

    You do know that chrome plated copper can't be used with push fit fittings ,unless the chrome is removed from the section that enters the fitting ?

    Yes i read that on here!

    Thanks for the reminder though :cool:

    Can you solder directly onto the chrome or does it also have to come off?

    It has to be removed to be soldered.You could use compression fittings.

    If you can though, try and avoid any compression fittings under the floor.

    I forgot to take a picture but it worked out well with solder fitting so thanks for your help

    I did notice that soldering onto the chrome pipe, even with the chrome removed was not as easy as normal copper it required more heat to get the solder to flow.

    I also had a speedfit elbow leak badly as the o ring collapsed into the fitting. I will always look inside them now before use to check they are ok!

    Thanks again
