Pocster Posted June 13, 2019 Share Posted June 13, 2019 (edited) Hey all A nice simple question ! Once I had got all the ufh pipes in I attached zip ties at strategic points to stick up through the screed . Undoubtedly these zip ties will eventually snap . As it’s a sand / cement screed can I just paint lines with paint ? . I don’t want to put something on the dried screed that will prevent / mess up the tile adhesive . Some photos of pipes !! screeders there today . “ we won’t block the lane mate “ .... ?? Edited June 13, 2019 by pocster 1 Link to comment Share on other sites More sharing options...
Mr Punter Posted June 13, 2019 Share Posted June 13, 2019 I can never work out why UFH pipe runs always have a very congested hot 'corridor'. In your second pic there seems to be 7 pipes in 600mm. It looks possible to alter the design quite easily but maybe nobody can be bothered. Link to comment Share on other sites More sharing options...

Ours was designed with all pipes in doorways and I asked on here why I could not run pipes through walls to save hot spots, reaction was why not. It saved mtrs of pipe runs, I ran pipes in insulation through the walls and it made it easier to install. 1 Link to comment Share on other sites More sharing options...

Needless to say this was the supplied design . Actually I got that wrong . That ‘clump’ of pipes are running back to the manifold which was behind me .

Conor Posted June 13, 2019 Share Posted June 13, 2019 Noob question, why do you need to mark on the pipe locations? Are you planning on drilling in to the screed at some point? Link to comment Share on other sites More sharing options...

Yes, mine was flow and return pipes for multiple zones to/from the manifold but easier to drill the walls and run more direct. Link to comment Share on other sites More sharing options...

Kitchen units probably won’t but nice to know where the pipes are . You never know !!!! Edited June 13, 2019 by pocster Link to comment Share on other sites More sharing options...
Ed Davies Posted June 13, 2019 Share Posted June 13, 2019 Friend had the foresight to work out where the post for his staircase would be and left pipes clear of the area to bolt that. Then there was a change of plan (something to do with BC being unhappy with the escape from a mezzanine area which wasn't a bedroom but which some future occupant might conceivably use as a bedroom, IIRC) so that the stairs had to be changed.. It'd have saved a lot of worry to know where the pipes actually were when it came to drilling where they were only 90% sure they weren't. 1 Link to comment Share on other sites More sharing options...
SteamyTea Posted June 14, 2019 Share Posted June 14, 2019 What can be done to repair a pipe once it is drilled though. Or how easy is it to repair a broken UFH pipe. Link to comment Share on other sites More sharing options...

It'd have saved a lot of worry to know where the pipes actually were when it came to drilling where they were only 90% sure they weren't. In our last build we designed the en-suite for a 900mm square shower tray and left the space underneath free of UFH. Of course we fitted a 1200 by 900 shower instead, and when cutting the hole in the floor for the trap, it took a few seconds to understand what was causing the pretty little fountain that started coming out of the floor. 1 1 Link to comment Share on other sites More sharing options...

My poor electrician was given 10 mins to install a protective steel plate over a cable for a floorbox before a concrete screed layer (to be polished) was poured. He put in four screws, and the drilling for two of them went straight through a UFH pipe. We didn't find out for something like 6 months, when we woke up to find the floorbox full of water and a puddle just starting to spread from the centre of the room towards the walls! Dug it out and used two straight couplings to patch in a loop of spare UFH pipe. Link to comment Share on other sites More sharing options...

I would think the second as you have to make sure that you do not damage anymore pipe and then the cleanup of said pipe has to be done well. Would it be possible to mark up the floor with a felt tip pen where the pipes are. If you use a good one, nice and fat and inky, it should still be visible after after any tiling has been removed. No good if it is a polished concrete floor. 1 Link to comment Share on other sites More sharing options...

No good if it is a polished concrete floor. yes complete pain in the arse but easy enough, in my case i was a first year apprentice joiner (back in 2006) i was given the job of fixing door stops to the floor the day before handover of a house , we needed to remove skirtings, lift the laminate flooring, lift the chipboard flooring dig up the biscuit screed, then had to wait a week for the couplings to arrive, my supervisor wasnt impressed it would be a lot more difficult in concrete as you would need to make sure you dont damage the pipe when digging it up Link to comment Share on other sites More sharing options...

Once the timber frame was up I called them to look . I ask when I should call them next - her answer “ when it’s finished “ . Perhaps it’s such a perfect job no one needs to inspect- or perhaps they are lazy .... Link to comment Share on other sites More sharing options...
