Re-Routing pipes

[Synforge]

Hi guys,

I'm in the middle of doing an en-suite with a wet room, when installing the shower former I think I'm going to have some radiator pipework in the way of my waste:





See the two pipes that go straight through at the back, these would need to be lowered to get the waste in place, unfortunately there's no real way for me to move them up as the joist can't have any more holes drilled further up.

What's the best way for me to lower these so I can get the wet room former in place? I think the space below is too small to put 4 elbows on it. Is there any kind of way to get a compact s bend on this? I should mention the pipe is Hep2o.

Any suggestions welcome!

Thanks

1. 4 elbows and some extra pipe so that the "U"s don't go straight down but gradually lower towards the front or back.
2. 2 nicely bent copper pipes with 90 degree couplers to the plastic.

Or put your foot on the pipes and see if there is any slack.
