Hi I've a mira minilight running from a fairly old vokera excell. All is well except once hot water gets going the shower starts to hum quite loudly
Its in a rented flat and my heating engineer has already tried to fix this to no avail. He fitted a pressure reducing valve and I think he may have removed the cartridge at one stage too- maybe to check for pressure reducers, I don't know
What commonly causes this? Do I really need a specialist to check water pressures/flow rates or whatever?
Thanks
