Hello, does anyone know how to remove the thermostatic cartridge from this concealed shower? The decorative collar won't budge (tried turning by hand, doesn't seem to be held in by a screw or otherwise). Not sure I should pull on the cartridge without removing the collar or other parts first...

Thanks for everyone's help so far. Took all the advice and searched online for a solution and got one that the building inspector has approved at 280mm thickness: https://www.multifoilsdirect.co.uk/solutions/superquilt-external-wall-ybs-superquilt/ Wall includes: - external render -...

My bad, the wall specifications came from the Architect initially and the SE agrees with them. The two building companies I talked to for quotes sounded flexible on the thickness of the walls (mentioned they could look at masonry/timber walls and material substitutions etc.) but the Arch + SE...

I've asked the patio door installers to go with their surveyor's suggestion (which is catnic). The more difficult job is getting the SE to budge on the extension wall thickness...

Thanks @RonnyRaygun From SE notes "Cavity fully filled with 100mm Rockwool cavity insulation per manufacturers' instructions and provide 50mm PIR insulation over vcl internally, e.g. Celotex GA4000" I read this about June 2022's changes: Under current requirements, an external wall U-Value...

Finally have some responses. Not sure what to make of them but am waiting to see what the patio door installers say. What's a 250x300x40 m/s plate? SE made a mistake and changed this to 250x300x20mm Why not use a 152x152x23 instead of 203 x 203 x 46? Cost; 152x152x23 will need a plate to be...

Sounds ridiculous now but I never thought to measure before :eek: Thanks for the tip!

Thank you everyone. Had to get my tape measure out - I’m getting 10 inch/25.4mm wall thickness. For some reason the architect’s been saying 9 inches all along and I didn't question it. On this basis the 250mm spreading plate works? Does this apply to a 10 inch/25.4mm thick wall? The beam...

Sharing this in case it's useful for anyone else (or if anyone can see a problem with this): SE has explained "They are not columns but plate spreaders of the beam which is a part of the beam."

The SE has emailed a new set of drawings. He's reduced that pier/return to 250 internal / 500 external and swapped the Catnic Lintel for a UC Beam. Hopefully he'll explain what's involved here... this looks like two columns at either end of the opening and a beam on top.

Thanks @RonnyRaygun - in your opinion, this is something common/standard for a SE to do or would I be asking him something unusual.

Appreciate any advice/pointers on this because my Structural Engineer has sent calculations for a door and aperture that don't add up I think (and hasn't responded for 2 days). We want to install sliding patio doors in the garden-facing back room which has an external width of 3430mm (location...
