MikeGrahamT21 Posted October 15, 2019 Share Posted October 15, 2019 Have you tried a pipe bending spring (as long as the bend isn't meters into the pipe)? Also try warming the pipe slightly with a bit of friction and this may help it be less likely to kink 1 Link to comment Share on other sites More sharing options...
Onoff Posted October 15, 2019 Share Posted October 15, 2019 Quite seriously we were taught to rub a pair of nylon knickers up and down plastic conduit like you're spanking the monkey to generate heat and aid bending. So you've a head start there! ? 1 Link to comment Share on other sites More sharing options...

AdamSee Posted October 15, 2019 Share Posted October 15, 2019 So what did you decide on in the end? I didn't realise that you could buy conduit from SF so cheap. I guess that works just fine with plenty to spare. Link to comment Share on other sites More sharing options...

Pocster Posted October 15, 2019 Author Share Posted October 15, 2019 Well it ain’t pretty but timber allows a Hep2o clip per pipe . Going under the render board ‘lines’ the pipe up to run across the ceiling . Not sure how good this will be really . Need to run a ‘ real’ pipe and see ...

Pocster Posted October 22, 2019 Author Share Posted October 22, 2019 I can confirm that washing machine waste pipe fits lovely in a 25mm hole . 15mm Hep2o glides through ! Was it @Barney12 or @joe90 I need to thank for this tip ? 1 Link to comment Share on other sites More sharing options...
joe90 Posted October 23, 2019 Share Posted October 23, 2019 @pocster it was Barney, I use flexible cable conduit which is very similar? 1 Link to comment Share on other sites More sharing options...

Pocster Posted October 25, 2019 Author Share Posted October 25, 2019 (edited) So I started putting the Hep2o in . Do they need more supports ? . They aren’t going to fall out the clips . But once pressurised will they jump / move as taps go on and off ?? I want some slack as they approach the manifold so I can demount it with relative ease if need be .

MortarThePoint Posted June 24, 2022 Share Posted June 24, 2022 Has anyone tried using UFH pipe formers with Hep2O? Annoyingly I can't find anywhere that says what the bend radius of these formers is, but they are massively cheaper that the cold bend formers that nobody stocks for Hep2O. I've copied the closest thing I can get to useable data below. I guess the 14-18mm one probably has a bend radius of around 125 - 25/2 = 112mm. Not in spec for the 15mm pipe's minimum bend radius of 120mm. The 20-22mm one is probably around 140 - 30/2 = 125mm but would probably be a bit loose/risky.

scottishjohn Posted June 24, 2022 Share Posted June 24, 2022 I maybe be wrong but if you used UFH piping rather than water pipe it has an alluminium core which will make it hold a bend ? no need for formers? or if you want to std water pipe hit it with the hear gun at the corners bend it round a half moonformer made from wood and it will stay bent when it cools Link to comment Share on other sites More sharing options...
