Apologies for asking a question which has probably been asked a hundred times (Google search didn't filter for me what I was looking for), and for not having basic physics knowledge, but...
If I lower the flow at the mains outside (Thames water installed stop cock) outside my property boundary for my house, will that lower the water pressure going around my system?
Some context:
I have a unvented system, with some type of 'megaflow' copy connected to a expansion vessel (no gauge so cannot read pressure), using a system boiler, of which I know is a Valiant.
During the times set for the hot water to heat, and for the first time of use of the hot water after that cycle I hear a bang coming from the Expansion vessel and its pipe. I dont know 100% for sure if its coming from the vessel but its around that area.
I'm not sure if it is of importance but I'll mention that the boiler is on the ground floor, and the unvented cylinder and the expansion vessel is on the first floor.
Thanks for taking the time to read and respond.
