I have a Worcester Bosch Greenstar 30i that loses pressures after the heating as been on. I've pressed the schrader valve on the expansion vessel and water comes out. I haven't noticed the the pressure gauge going over 2 bar or leaking outside. Can i drain out the boiler by turning off the flow and return valves then pulling on the red lever of the PRV to drain off outside to replace the vessel ?
