Hi Ian sounds like air lock, try this turn off stop cock all taps closed start upstairs first open cold water sink and bath flush toilet, leave taps in open position, open all down stairs taps remove washing machine hose and open valve to drain the same if you have dishwasher,close all taps starting downstairs need two people to do this one person to regulate stop cock other person to open taps, all taps closed, the nearest tap to stop cock crack open so it will just let a small flow through, open stop cock the same way small flow only, let it bleed through to first tap you cracked open when you get a flow through continue to next tap and this will eventually bleed all the air from the system good luck
