I wonder if its the shower unit itself. The taps that run off the same pipe seem fine. I'm reluctant to change the valves as it means cutting the wall open.

Ah that could be it! I used some speed fit isolators onto copper, so they could be smaller bore? This is what I used https://www.screwfix.com/p/jg-speedfit-15sv-isolating-valves-15mm-5-pack/25911 Not clear from the description.

Hi I’ve installed a new bathroom in my dormer conversion. The flow rate of hot water to the rest of the house is fine. However, in the new bathroom it’s pretty feeble. The only thing I can think of is that it sits above the boiler whereas the other 2 bathrooms are lower. It’s a combi boiler so...

Hey everyone I’m going to be lifting and relaying some tongue and groove chipboard in my dormer conversion. It’s been laid badly by whoever did it. They’ve laid it in a stack bond fashion 4 corner joints touching) and nailed it down. It’s squeaking a lot and I’m getting new carpets shortly so...

The tiles are 18kg per m2 (only 9mm thick) so with 4kg for adhesive its under the 32kg/m2 limit for plasterboard. It’s just a cost save for me tbh. The Hardie boards are being used over the bath for the water resistance. But to do all of the walls in it would add at least another £400 to the...

I can’t seem to find a product called bal tile seal. Would Sbr have the same effect? The masonry wall is a bit patchy as it was plasterboard dot and dabbed onto a plaster on brick surface. I’ve knocked all the plasterboard and dot and dab off. But it’s got some chunks out of it. As I’m using...

Thanks Wayners. So seal the plasterboard then once tiled and grouted use BAL sealer to seal the tiles? I’m using ultra s1 spes flexible adhesive and Mapei ultra colour plus grout if that helps. How often would you screw the plasterboard onto the masonry if you were using plasterboard adhesive?

Hi I’ve got some of the blue plasterboard being delivered tomorrow. I know the majority of advice is to tile onto cement board. But hoping it’s going to be quicker and a bit cheaper using the moisture board where there is no direct water contact. I’m just ripping things out and I’m amazed...

Interesting. Downstairs I actually get pretty low humidity. Regularly in the high 30’s. I’m wondering if the window vents will be enough. I’ve got some wet rot hardener, worth putting a bit of that over it? I’ve got 2 pack filler and loads of zinsser bin so assume that’d be a good start...

Hi I’ve got a velux style window at the top of my stairs going into a dormer conversion. There is quite a bit of black mould around it. Most likely because the vents have been closed. So I’ve opened those up but still need to get rid of the mould and sprayed white vinegar onto it. It looks...

Thank you. This seems to have done the trick. Really annoyed I didn’t try that before replacing the valve! At least I know for next time now. Cheers.

Microbore 8mm with a reducer to make it 15mm for the valve.

I’ve replaced the whole valve and direction isn’t an issue. But still got the noise. Could it be done burrs on the pipe or something?

Good shout on the direction. I’ll have a look, thanks. Useful tip checking which gets hot first. It’s a brand new trv and it made no difference to the sound so I assume it can’t be that.

Hi I’ve read some threads on this but still unsure. Only one of my radiators in the house does this. There is a high pitched whistling noise. Like an old kettle sort of noise. It disappears when I turn the trv down. I’ve tried replacing the valve but it still does it. It also makes a tapping...

Thanks all. Ordered a different waste off Amazon and that fit much better. The silicone wasn’t too bad to get off the previous one either. The tip on wd40 was great. Took 2 mins to take it off and I’ve not put it on the new one. Did try to use the basin mate but the thread wasn’t long enough.

Haha. That was me. The thread was a bit weird. I think some of the issue could be the waste itself. The YouTube video said to silicone it so was just following that but the thread did slant to the side a bit I’ve got a basin mate for when I replace it next. Good to know. I might try a different...

Yeah think you’re all right. Just got a mcalpine waste and it’s fitting much better. Annoyingly it’s not Matt black on the top like everything else in the bathroom. So might try ordering a different one off Amazon and see if that works better than the one I’ve got. Any tips on removing the...

It’s almost like the thread is too small for the trap. You can wobble it off. But should both be 40mm. The leak is coming under the nut where the blue arrow is pointing. Everything above it appears dry so I’m assuming it’s the looseness of the connection. All the parts are brand new. Wouldn’t...

Hey all I’ve just fitted a new basin and the thread on the waste is leaking. It’s coming out underneath the nut that the trap is screwing on to. It’s a mcalpine trap so I don’t think it’s that. However, when I screw the trap on. It doesn’t go tight it just keeps turning. I tried some ptfe but...
