Have just spoken to WRAS about food safe materials again and they said the only materials which can used within the tank are that either a) compliant with BS6920 standard; or b) WRAS-approved.
Not sure I understood them correctly, but I think they said that the air gap requirement in the tank...
Many thanks, Rob, for your advice about the food safe sloped platform. That feels to me as a sensible thing to do that would bring the noise level down.
Would you have any examples, pictures or drawings that will demonstrate it? Are out there any specifically made for the purpose or you would...
Thanks, I'll ask if they have been added at the later date, but I feel they might have not. Is it a requirement to have them or a good practice, or both?
Thanks, it was at the time when the pictures were taken about 3-4 months ago. I don't have the recent ones.
I believe the have done lagging since then and added soundproofing around the tank.
Re rubber shoes inside the Munsen rings: Do you mean rubber rings around the pipe, as it looks they...
By the way, here are the pictures of the tank. Any comments about the tank, piping or the valve?

Thanks. I don't think that is possible. That area, unfortunately, seems the most suitable one for the purpose, but I will ask. I guess the cost would be massive too and have to be justified.
I had an update today, and the have decided to install Keraflo valve, that was mentioned by Nige.
I...
Thanks, Madrab. I believe that's exactly what they have additionally done already - insulating the water tank in soundproofing material.
However, the sound without the encasing was very loud and constant, and while now we have soundproofing from the sides and the top, there is no soundproofing...
Thanks, Nige. I'll definitely enquire about that. Hopefully they will allow us to test the valve, rather than simply committing to it irreversibly.
My only worry that with this solution it would be very loud early in the morning, 5-6 am when everyone starts waking up, meaning that all overnight...
Thanks, I'll ask them if they considered the solution. Would this mean shorter periods of filling time with louder intensity, as opposed to quieter but non-stop filling of the water?
Not sure it will help as the tank sits on the concrete/metal combo on top of our ceiling and it feels that sound gets transmitted to the walls as well as the result. And I am not keen on it at all, as the ceiling is not that high in a small room.
I was more thinking about redirecting the flow...
