I have to route blue MDPE (plus insulation) round a couple of bends
(through the foundation, then up to the stopcock) inside 110mm
drainage pipe, and I had a look at the MDPE in wickes. It doesn't look
very flexible, so what is the smallest bend radius you can use ? Would
it go through a standard rest bend OK ?
Simon.
If its the same stuff as my water main inlet then that comes through 110
mm
pipe with a 90 degree on the end.
No insulation though.
Does it appear forced against the edge of the pipe where it exits,
i.e. trying to fight against the bend ? Is is a standard sharpish 90
degree bend ?
Not that I can see but I think there is a short straight which helps.

Maybe I am just being a wimp about this !
Can you not just try it and see first?

Simon.

Yes, but I'd like to be able to order the lot in one go.
I think I have convinced myself to use rest bends to bring the water
up. It must go round them, I mean drain rods do ! I've also managed to
work out a layout for the ducts, so that my drainage and water do not
get into a total tangle !

What happens if you warm it up first by immersion in hot water?
