OK, if it's the wet wall that's flexing then it may not have been fixed to the subsurface properly at that point. If the shower was done as part of the same job as the wet wall, then they should have made sure between them, that wherever the fixing points of the shower was going to be that they...

So the PVC wet wall behind the brass fixing bracket, that the bracket is actually fixed to, is flexing as well?

Can't see from the vid if it's the brass bracket that's fixed to the wall that's also moving along with the wet wall or if it's just the brass riser, that's fitted into that bracket on the wall (with the lever that fixes the adjustable height riser) hasn't had the allan key grub screw tightened...

That was just explaining that 50mm was an option and is the largest of waste pipe sizes and that the one from SF comes with a reducer I believe that drops the size to either a 40mm or 32mm, so I would presume the size of the AAV itself would be 50mm. As other have suggested though if you...

If you are to follow Yep - Largest domestic waste pipe size you'll get SF actually do a universal AAV for all 3 normal waste pipe sizes https://www.screwfix.com/p/floplast-solvent-weld-air-admittance-valve-white-32-40-50mm/42968

If it's not at least SDS then I would suggest it's not really designed for coring, that being said not all rotary guns are just for coring. The key is to ensure it's is clutched otherwise the first jammer you hit might take you wrists out. The actual diamond coring set are subjective IMO...

We always wrapped copper when it was to be imbedded in concrete or plaster but then found out it wasn't required and it seems (edit) it may be a bit of an urban myth This is more about concrete but includes plaster in it's comments -...

Nope - still doesn't make much sense - Section 10 is about enforcement - so not sure what they are talking about, unless it's a subsection of one of the other provisions. The only reason I can see, given the mention of air gaps is it's about backflow but that's under Parag 2 Sect 15. It would...

If you are talking about tubular column (designer) rads then invariably there are 2 camps. One that says they work fine and the other that says due to the way they heat the air around them (they have a higher % of radiant to convecting heat profile than a traditional convecting rad), they have...

Weird one that. Reg 10 of the water regs is about enforcement. Not sure what section 10 they refer to would be then, unless it's something to do with backflow (part of the regs) or possibly stealing flow to the cylinder (not part of the regs). Do you have a link to the MI? The whole point of...

The system could certainly be re-commissioned but as suggested, depending on your level of handiness you could do some tweaking with the system as is, or if very confident, reset the system back to standard settings and start from scratch.

Are you talking about removing the appliance waste adapter T piece? As others, what are you trying to achieve? If it is to remove it then a trap to waste extender would probably do the job though they aren't usually as long as that T piece would be.

Difficult one without anything to show the design of the system, or at least a description from the owner who installed it. Also looking @ loop 3 (from the left), even with the actuator open there doesn't seem to be any flow? I'd also have caps on the 1st port in/out - just in case. If the...

TBH - The RGI (LPG) should be able to check and sort out any required ventilation the install may require.

Absolutely - I usually get them off with an adjustable spanner held just at the right angle on the flats, or a pair of vice grips. Nothing beats getting the knack for it after doing something hundreds of times.
