Nickfromwales Posted November 11, 2016 Share Posted November 11, 2016 They're only ever going to be at =/< 2 bar so I'd not panic too much about 2 compression joints behind the rad, I've done it hundreds of times converting copper to chrome via compression bends or couplers. Ive had more immediate failures with soldered joints than compression tbh. Famous last words Link to comment Share on other sites More sharing options...
Onoff Posted November 11, 2016 Author Share Posted November 11, 2016 Fair play to that eBay seller @Nickfromwales put me onto. I ordered those 16/15mm parts this morning and they've already shipped them. Went for standard delivery. Fingers crossed for tomorrow. Link to comment Share on other sites More sharing options...

Onoff Posted November 11, 2016 Author Share Posted November 11, 2016 Back to thinking copper might be better now. This almost fits and I reckon once I add the thickness of the tile I might get away with it..... Link to comment Share on other sites More sharing options...

Onoff Posted November 12, 2016 Author Share Posted November 12, 2016 (edited) 7 hours ago, CC45 said: Thinner insulation just behind the pipe & drill hole further back? CC Could do. Was trying to get as much on that wall, well, 50mm min tapering to about 100mm the other end of the wall at the wet room corner. The bottom of this cavity wall has so much debris in you could call it rubble filled/solid! Have a look on page 4 of this thread, I'm a past master at veeing out insulation to take pipes! Not too worried about having chrome pipes as chrome effect covers are available. http://m.ebay.co.uk/sch/i.html?_nkw=Chrome+pipe+covers&isNewKw=1&isRefine=true&mfs=GOCLK&acimp=0&_trksid=p2056088.m2428.l1313.TR3.TRC1.Xchrome+pipe+covers&sqp=chrome+pipe+covers Edited November 12, 2016 by Onoff Link to comment Share on other sites More sharing options...
Onoff Posted November 12, 2016 Author Share Posted November 12, 2016 Tbh I really should get the towel rad so I can set these pipes in for good and gauge the finished height. I'll likely need to add additional battens too. 1 Link to comment Share on other sites More sharing options...

So chrome is much harder than copper and the retaining "teeth" in most push fits can't bite into it to retain the pipe correctly. Only real choice is clean it off with emery paper but watch you don't create too rough a surface. Link to comment Share on other sites More sharing options...

I foooishly assumed that was a given, so yes, NEVER put chrome pipe into ANY speedfit fitting. . Good shout Peter . Link to comment Share on other sites More sharing options...
Onoff Posted November 12, 2016 Author Share Posted November 12, 2016 Just ordered the rad: http://www.britishbathroomcompany.co.uk/phoenix-zonta-600-x-1000-polished-ss-radiator-ra320 Will order the valves Nick said too. Link to comment Share on other sites More sharing options...
Onoff Posted November 12, 2016 Author Share Posted November 12, 2016 (edited) A bit of gap filling with some 50mm EPS. Only 200mm deep until it hits the first ties. A line of low expansion foam one side then popped it down the cavity and properly dosed the side between the EPS and outer leaf. That should fill the gap nicely. I'm going to infill atop the line of blocks with strong mortar levelled to the stud batten. I'll then trim the foam flush. Should give me a decent base to fix/stick my DPM all round the reveal. I WILL banish these draughts! BUT.... I knew I had to revisit the batten fixings under the window but where everything has dried out they're as loose as the video below shows: The concrete screws used to affix the battens haven't moved. The solution: Edited November 12, 2016 by Onoff Link to comment Share on other sites More sharing options...
Onoff Posted November 13, 2016 Author Share Posted November 13, 2016 Multisolve.....seriously what makes it "magic"? Spray on and it smells / feels greasy then it's just.....GONE! I've been cleaning old bits of DPM with it and sticking to the reveals. Like s*** to a blanket! Link to comment Share on other sites More sharing options...

Nickfromwales Posted November 15, 2016 Share Posted November 15, 2016 +/- 2mm worrying you ?!? Given the shape of the room at the start you should be patting yourself on the back mate Link to comment Share on other sites More sharing options...
Onoff Posted November 16, 2016 Author Share Posted November 16, 2016 Hmm...to go square or not? Got the insulated plasterboard on the sill. Sikaflex round all 4 edges then a good zig zag of low expansion foam in the middle. All level and weighted down: BUT...doing the sides of the reveal and the piece on the rhs kicks in by about 8mm at the back. Tbh it's nice and in line with the upvc frame. I can't see it'll mean anything else other than cutting a tile stop the sill. If I try and bring it out to the line I'll have a big hollow at the back of the insulated plasterboard. I'm looking for a good contact area as I'm foaming it to the blue DPM that lines the reveal. Any thoughts? Link to comment Share on other sites More sharing options...
Onoff Posted November 16, 2016 Author Share Posted November 16, 2016 Went with my gut! Scuffed the DPM with 60 grit paper then cleaned with Multi Solve. Sikaflex round the edges then Soudal low exp. foam in the middle and a few packs. (Second side was neater). Held the board on with a few strategically placed bricks and wedges. Happy with the "panel gaps", i.e the board line in relation to the UPVC lines: Link to comment Share on other sites More sharing options...

Put bluntly, no! EDIT: Measured with bleary eyes this morning and it's 9-10mm from the face of the plaster board to the glazing bead line. All I can do I guess is set the trims round the reveal so I get a tapered bed of adhesive down to "nothing" at the back with 8mm tiles. You know how you learnt (learning?) me plumbing.....well wait for the numpty tiling questions! BUT...no draughts! So worth the hassle.

Nickfromwales Posted November 17, 2016 Share Posted November 17, 2016 Use sika to bond the tiles on the reveal so you just end up with the thickness of the tile against the window. The sika can be fag paper thin and still hold like a chav with a winning scratch card. 1 Link to comment Share on other sites More sharing options...
