Just saw someone on another forum suggest dot and dabbing tile adhesive to the back in the void sections and then drilling through with mechanical fixings when dry. I'll be using tile adhesive on the boards anyway to fix them to the walls, so that would cut out a step and so be a lot faster, is...

Love it, thanks mate

I think I posted this in the wrong forum initially, sorry! I need to put some wedi boards on the wall for tiling. When the old tiles came off they left a recess behind them -- there's old plaster, then two feet of bare concrete blocks that the tiles were stuck to, then old plaster again below...

I need to put some wedi boards on the wall for tiling. When the old tiles came off they left a recess behind them -- there's old plaster, then two feet of bare concrete blocks that the tiles were stuck to, then old plaster again below where they were. The gap's a centimeter or two, larger in...

Fair enough! Got really rattled when my first try at attaching it failed. Simplest answer is I didn't tighten it properly -- I was just casting about for other reasons cos I'm desperate for it not to fail again.

It's still holding ... Here's a picture of another offcut. As you can see it's pretty thick and sort of wedge-shaped.. The other one had a more pronounced wedge and completely flat back end.

I'm not taking it out again!! But I'll have a look in the morning and see if any of the other parts have one on. Some of the others fell apart when I took them out, but the one I reused cleaned up to nice bright copper.

Whatever it was had held for who knows how many decades before I got to it, so I hope it will still be sturdy now it's back in.

Just read this and it doesn't sound like what I was dealing with though ... It was an ordinary section of half inch pipe, no flared end, just a sort of pyramidal olive. I just assumed that was what olives used to look like back in the day.

Yes it's an odd shape -- comes down to a point at one end, broader than a normal olive at the other. If you took a cross section it would be triangular. I'd never seen one before!

Actually that was why I went back to reuse the section of old pipe -- the olive on it was absolutely rock solidly attached when I took it out of the fitting. That was what made me think it was a better bet to go back in. So that's a good sign anyway. Thanks for all your help here mate, I really...

Might have been under-tightened, it was hard to reach. I thought I was really cranking on it! Always a tightrope when you're also trying not to over-tighten.

It's 1/2 inch pipe. Not sure why it failed. The nut is the original one from the old fitting, and taking a close look at it my guess was that the external diameter of the 15mm olive wasn't large enough somehow. It fit on the pipe well enough. Where I've had to do the larger sizes I used...

I'm having to work with both imperial and metric pipes and fittings in an old house. Earlier today I put a 15mm pipe with with olive into an imperial fitting, tightened it up, only to have it burst out when I turned the water back on. I had thought -- wrongly!! -- that because the imperial pipes...

Details of the white boxes and circuits attached. There are three cables that go into the white trunking underneath. I had wondered (not being an electrician) if it would just be possible to take the cover off the consumer unit, dismount it, and screw it back to the board a little higher up...

I've been asked to build a cabinet for a consumer unit. It's not the prettiest! I've got a question for anyone who's done this before, or who has seen a similar setup before -- the two wires on the right which dip down below the top of the architrave are going to be a pain in the arse. I can do...

I was advised by a guy in the shop to get 6mm wedi board for tiling a shower cubicle. After attaching the wedi to studwork on one of the walls I called wedi just to check and they advised that it should be 10mm minimum on studwork. The studs are sizeable, closely spaced, and very well fixed. Am...

Yes that's exactly it -- there are general guidelines for wedi here: https://justwedi.co.uk/pdf/AE.Building%20Board%20Installation%20Guide.pdf -- but it may be different for Jacko. Here it says that the screw should go to a minimum of 35mm, but I was advised 50mm elsewhere and went for that...

Sorry, didn't see this just now so it's probably too late -- I was advised to have the screws go at least 50mm into the wall, so I went with 70mm to be sure.

I had to use 6mm but spoke to a tiler and they said it would be ok -- the narrow size of the space was a constraint. I'd been worried that the thickness of the adhesive would built it out too much for the tray to fit, but it ended up working out ok. Anything thicker and I'd have had to bring...
