    Bending pressure pipe

    Hi all. I've just acquired a new filter and have a slightly pipe misaligned on my bd. It's only about 20mm so trying to offset with a 45 elbow won't work (there isn't space).
    Has anybody successfully heat bent 4" pressure pipe?

    Saw a chap on YouTube, his channel is called keeping it koi, used a heatgun and with a bit of trial and error he seemed to have reasonable success

    Hovis have you ruled out using a flexible rubber straight connector instead?
    I was able to heat up and manipulate one when I was slightly out of line

    It's going direct from the bottom drain pipework to the drum inlet. I've only room for the required 90 to bring it to the drum. TBH they'll probably be enough flex in the 90 but I don't really want to put them under more strain than needed

    If you have enough pipe length to play with you could try using 2x 45's with a bit of straight pipe in between them. You can pretty much manipulate the pipe into any kind of offset you desire.

    Similar to what I had to do when fitting the new drum:

    Alas I only need about 20mm or so of offset but can't push the filter further back to allow for 2 45 degree bends. All rather frustrating. I'll have a go at bending some pipe and if that fails try something else!

    Neat set up you have there

    Thanks for the kind comment.

    You can buy 4" / 110mm flexi pipe. It is not cheap and I can't remember who supplies it, but it may be a solution.
