Or just ask your BCO about using what you have, I find they all interpret the rules differently!!!

I don’t think so but you need to get deeper door stops as posted above.

The intumescent strips can be fitted to either the door or frame, not both, the door jam has to be larger as well. “Door stop not less than 25mm deep and 38mm wide glued and screwed to the existing doorframe at 300mm centres.” https://www.corby.gov.uk/sites/default/files/Information sheet 2 - Fire-resisting door assembly.pdf

I would, remove the screws and pull the Chanel off, . When the Ali and wall are cleaned off, silicone to the back of the Channel and screw it back to the wall cleaning off any silicone squeezed out. Replace glass and push the “gasket” back in. ?

Then how was it secured to the wall?

Not sure that’s right, that’s the case where the glass has a channel fixed to it and it slides into another channel fixed to the wall. From that picture the ally is fixed to the wall and the glass is pushed into the channel and held by the clear gasket stuff. Just more brute force I suspect but glass is difficult to grab hold of. Anyone else?

It is a non return valve in that it only allows water to flow in one direction.

No mate, it’s inside the lower connection and only visible by removing the casting from the rails. It’s not that I want to remove it, it’s just that it lets water through it too easily so when the pump is running it’s easier for the water to bypass the pipework from the buffer tank, it just circulates water round the UFH loops. My blocking it off works well as long as the TRV is removed otherwise the pump could burn out pumping against a full blockage. I am relying on the buffer stat to regulate water temp and will monitor it regularly. The heating (manifold pump) is controlled by a room stat.

As you all know when I went to appeal the inspector informed the council they were not abiding by their own policies so yes I have no faith whatsoever in planners. The last paragraph is interesting though, My conclusion is therefore not to correct the notice but only to quash the notice. The matter of the use of the building would need to be resolved, without prejudice, by a future enforcement notice, or by a lawful development certificate or planning application. that’s an open door fir the council to challenge the “use” of the building, if they can be bothered ?

Mine is installed in the loft, hung from the rafters and it cannot be heard unless on boost ?

But you said

But surely you need to compare rainfall for a set area, per sq m or something similar. When I was at school (in the dark ages) a rainfall gauge collected rain fir a given area?

No i didn’t do white. (Completely)

The trouble is you pay for the water and they charge that a percentage goes down the drain whether it does or not!,

I am not sure using it as an office is classed as “habitable “, I know bathrooms aren’t but bedrooms are. A mate of mine had similar in his house, fold down ladder but he did insulate it and instal velux,s and his son used it as a bedroom but when he sold it it was classed as storage.

Many times, unfair tho with so much rain in our part of the world, perhaps you could instal rainwater harvesting

But you will use more hot water and energy ?‍♂️, only joking, do you have a 1500mm bath? (I hate them unless only showering over one).

Ha! this noise must have been air, ran it for a bit, let it rest then bled it again and it’s gone quiet ?

It appears to be pressed into the casting and I can’t get to the back of it to give it a clout! ?‍♂️

It’s in the connection between the lower rail and the bottom of the pump. It acts like a bypass in case the TRV shuts so the pump can still move water and also allow cool water to blend with the hot into the pump. @ProDave was right that the NRV was opening as it gave less resistance than the pipework back to the buffer tank 10m away. It would be good if I could adjust the spring in there so it would only open if the TRV shut.?

Yes I doubt anyone would notice but you could always add a bit more insulation I suppose ?.

Just noticed that the pump on the manifold is much more noisy whether turned up or down . It does go quiet if I shut the TRV but I guess not good for the pump as it’s not able to circulate the water now the “bypass” is blocked?

Yes. https://www.premierloftladders.co.uk/fire-rated-loft-hatch/

I know one in Bristol ?‍♂️

Yes!
