PeterW Posted May 18, 2020 Share Posted May 18, 2020 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 Link to comment Share on other sites More sharing options...
Coops Posted May 18, 2020 Author Share Posted May 18, 2020 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? Link to comment Share on other sites More sharing options...
PeterW Posted May 18, 2020 Share Posted May 18, 2020 Sleeve it with some cheap foam insulation but as long as its min 250mm and heading down it should be fine Link to comment Share on other sites More sharing options...
Coops Posted May 18, 2020 Author Share Posted May 18, 2020 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 Link to comment Share on other sites More sharing options...
PeterW Posted May 18, 2020 Share Posted May 18, 2020 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 Link to comment Share on other sites More sharing options...
