Pushfit connection to washing machine

    Hi, I am looking for some advice on how to best connect a pushfit system to a washing machine. A PEX pipe is flexible and even with talon grips screwed down to the wall it bends under the weight of the washing machine hose. From what I read, side loads are a "no no" to pushfit connectors, so even a copper pipe would not help much. I could not find a 3/4 BSP pushfit wallplate, that would be ideal in this case.

    Bit of 15mm copper into washing machine valve (which incorporate a non return valve btw) clipped to wall with two clips, and a push-fit coupler with appropriate insert to connect back to the plastic.

    While experimenting I came to the same conclusion as you that the last bit of pipe before the WM must be copper.

    In your advice, did you have a compression or a speedfit valve in mind? I ended up fitting a compression fitting, which seems to be much more tolerant to side loads (the weight of the WM hose in this case).

    I always go for compression personally. Copper olive and a turn of PTFE around the olive always works for me.

    Isn't tape around an olive not only unnecessary but can also stop the olive compressing correctly?

    Not a criticism, just a question.

    I've never had a problem, I tried paste but never get on with it. TBH the brass olives are really soft so it's easy to over tighten them into a squashed mess.

    Thanks, never used paste or tape.
     
  8. PTFE tape on a compression fitting is a bodge and also looks a bodge, if anything is to be used a smear of paste is all that is required.

    One paste I do quite like is LS-X
