Swapping hot and cold

[amfisted]

Evening all

Pic shows a run of pipe emerging underfloor from Lord knows where, and terminating in feeds for a bath. The bath has been removed, those feeds are capped off, and I want to divert the pipes in the pic up the wall to feed a mixer shower. However, the hot feed is on the right (22mm, so will be reduced) when I need it on the left for the mixer. What’s the best way of swapping the pipes? I’ve got a vague notion of crossing them over by bending, but I don’t know if there’s room to do that before the pipes have to be secured in the wall channel on their way to the mixer. Any useful advice welcome, cheers.

I can't see a pic. but does your mixer not accept either fixing.

Thanks for the reply.
Not sure because I haven’t ordered it yet, but I assumed that hot on the left was standard.

Have a look at the shower you're buying you can sometimes change the orientation of the shower to accommodate this setup. Hot is usually on the left, but look at the shower type first.

Thank you. We've had a very competitive quote for a shower unit that ticks all our boxes. All our boxes, that is except the option to swap hot from left to right. Its too tricky and labour intensive for me as a DIYer to swap the supply pipes around ( this is only a two bedroom bungalow but there's a positive "Spaghetti Junction" of pipes under the floor) so it looks like I'll have to cross them over on their way up the wall to the shower outlets. Shouldn't be too difficult because the chase I've cut rivals the Grand Canyon for depth.

My shower unit comes with flexi’s so easy to change orientation, just hangs on wall brackets.

You have two pipe sizes there, 1/2" or 15mm and 3/4" or 22mm. The 22mm will need reducing and that will give you extra space to swap the feeds to suit your mixer. Pulling an underpass is easier on 15mm than it is on 22mm

Good idea, is that. The one we’ve picked is a bit more conventional, no flexis, just “left and right”.

“Pulling an underpass”...I like that

Normally I would do it all in copper but I'm more used to bending & soldering etc. This though could be an instance where plastic can be your friend being a lot more flexible, just until they have cleared each other, then back to copper into and up the wall.

Aye, could be good. Just don't use too many fittings

Thanks again and yes, that's a fair point. I've already bought the copper and I'll "dry run" it to check whether its feasible to cross the pipes over as they climb my Grand Canyon. I think it will be, but if not then yes, crossing in plastic would be better than hacking more chunks out of the wall and risking a major collapse.

If you do not access to a tube bender for pulling offsets, then four of these will enable you to make an underpass and an overpass to swap over the services.

Thanks for that. My options are mounting up nicely, thanks to you guys.
