Jimbouk Posted April 24, 2017 Share Posted April 24, 2017 So I had a trip to Wunda Trade today and now have a hilux full of ufh pipework and associated gubbins... We are using the staples to attach to the celotex or rather the membrane over the top and into the celotex. Just wondering if all the celotex slabs should be taped as well, or is that just over kill? Going to be using a dry screed. Link to comment Share on other sites More sharing options...
CC45 Posted April 24, 2017 Share Posted April 24, 2017 We taped all ours. Easy and not especially costly to do now. I assume you've got some plastic to cover them before laying the ufh pipes. Cc Link to comment Share on other sites More sharing options...
Jimbouk Posted April 24, 2017 Author Share Posted April 24, 2017 Thanks, think we might as well tape it, what gauge plastic did you put over the top? Link to comment Share on other sites More sharing options...
PeterW Posted April 24, 2017 Share Posted April 24, 2017 Just a bit of advice - make up the pump set and then loose fit it to the manifold and then tighten up the manifold bracket screws.... Wunda sometimes send them out loose, and sometimes tightened up to make you think that they are set to the "correct" pump spacings... They aren't..! Ask me how I know...

Jimbouk Posted May 2, 2017 Author Share Posted May 2, 2017 (edited) Thanks for the tip, have not got as far as the pump set yet. Just assembled the manifold and system and pressurised prior to the screed going down. This was quickly done last week as a temp installation, to check the pipe work and have it pressurised whilst the screed being laid. Contractor called me from the site this morning to say that the pressure had dropped down to 1.5 bar, before they started, so I suggested they re pressurised. All good. I turned up on site late afternoon, screed almost finished, great job. Just as they were about to leave, I go and check the pressure gauge, dial pointer at zero..... Called them back, dial at zero, looks of concerning starting, no leaks, I go to repressurise, so that we can try and identify where the leak maybe, dial does not move. It was stuck on max all along, rather embarrassing, but a good outcome! Edited May 2, 2017 by Jimbouk Link to comment Share on other sites More sharing options...
CC45 Posted May 2, 2017 Share Posted May 2, 2017 Ive been surprised how much the pressure varies in ours. It went in a while ago and has been left pressurised since - in winter it dropped by 1.5 bar (so I recharged it) but a few weeks ago during the mini heat wave we had, I let some out! Like you I did worry about leaks when the pressure dropped but confident that its just temp variation now. Link to comment Share on other sites More sharing options...
PeterW Posted May 2, 2017 Share Posted May 2, 2017 Mine has been on 1 bar pretty much for 6 weeks - I reckon any leak is past the threads on the temporary plugs for the fillers Link to comment Share on other sites More sharing options...
