Default mains water pipe diameter - want a bigger one

I bought a roll of 25mm MDPE blue pipe from my local merchants, dug up

the
front garden and drilled a big hole through the front of the house to

get
the pipe through to the sub-floor space. Be sure to sleeve the 25 mm in
28mm or 32mm plastic waste where it passes through the brick.


As it happens I need to do this myself soon; and have been scratching
my head over the specs diagram I've just received from the water co.
It shows the MDPE pipe coming through the wall, minimum 750mm below
ground, sheathed in another pipe as you describe. However, it
stipulates that the min radius of the sheathed pipe is 750 mm! ie, as
drawn, it must come up through the kitchen floor at least 750mm from
the outside wall! This bears no resemblance to any installation I've
ever seen, and makes no sense to me at all. Can anyone shed some
light on this???

750mm! Forget it. There is not one of my properties that complies with
that.

Like all things DIY, when working on ones own property, you will be far more
cautious/careful than any 'approved' installer. When I suggested the
sheathing to the guys that turned up to do the connection they just laughed
at me. Seriously!

Everyone I have spoken with has said that MDPE is stronger than it looks and
not to be too concerned with scratching it or compressing it etc. Of
course, wanting to do the job properly, I ignored them all and took care of
what I did, running it under the (to be installed) concrete floor within an
electrician's 50mm conduit which was available with a nice radius bend that
brought it vertical to my kitchen wall without having to sink 750mm down. I
also used this to run a few cables along, which was helpful.

Frankly, ignore the 750mm spec and do what you feel is correct. The guys
who come to acutally connect the thing in the road will know a fraction of
what you do.
