Yes. I have no loft as such. The house was built with the loft space as a room with en suite. It also includes an airing cupboard with Sadia megaflo 250lt tank. I can see no other storage for the cold taps. When I turn off the main stop cock the cold taps do not stop immediately but I can not see any storage tank.
The pressure in the utility room is way above 1 bar.
Where could the pressure reducing valve be? that was my initial thought but I also that it would be visible and accessible.
I have a red tank in the airing cupboard which is about 20 cm tall which I believe is the expansion tabk for the central heating.
Is the megaflo also supplying the cold taps then? I thought that it was only hot water.
I understand the pressure build up inside it from the cold supply, idea, and the hot taps give a real high pressure output for a short time but then they drop which seems to be right.
There are two pipes going into the small roof space above the "attic room" from the airing cupboard but I have not had a good look up there believing that everything was below that and that those were presseure relief pipes. I will go now and check it out.
The pressure reducing valve must be OK as the pressure at the utility room sink is very high but the pressure for the kitchen sink and all bathrooms is low..
The Sadia Megaflo is a CL250
I cannot see any other tank in the roof space just the two pressure relief pipes leading towards the eaves.
I can see the cold feed branching out to the kitchen and I guess everything else after the main stop cock. The downstairs wc has good pressure.
"Pressure reducing multi valve" as in main stop cock?
I will try the repressurising the megaflo but if its not related to the cold taps its not going to make much difference is it?

The pressure reducing valve effects the hot water and cold water as both branch off after this
sorry I lost you.
I viewed the photo and when I closed it iu was disconnected from the site.
I have a valve like that in the airing cupboard at the top of the house.
Its connected in the cold line
