New water main installation.

Yeh just run a length of 32mm waste pipe down the hole first to stop it scratching the MDPE and put an elbow on the bottom as you won't get a neat curve with less than 350-400mm radius and you will just kink the MPDE

[Coops]

Yeah, that sounds doable, only thing is, at the point where the mdpe will exit the external wall it won't be anything like 750mm, do you think it would freeze?

[PeterW]

Sleeve it with some cheap foam insulation but as long as its min 250mm and heading down it should be fine

[Coops]

Brilliant..one last thing before I order the gear, supply side is 32mm,I'm going to reduce to 25mm does that seem right to you. (Might be worth noting water pressure not good, the other residents have had to install booster pumps)

 

Thanks 

[PeterW]

Run 32mm to the elbow the reduce to 25 into the house, easier to drill and connect onto 22mm from there

 

And you may find pressure is better with MDPE
