Hi
My boiler is serviced each year. Last year it was noted that the pressure was high and the expansion valve was defective and needed replacing. The engineer gave me a price to supply and fit and I gave him the go ahead. However, pandemic kicked in, have chased the engineer who says he is ultra busy and can't get back there just yet.
I called Vaillant and arranged a one off fix - they have come out and said nothing wrong with the boiler but the radiators need flushing. The radiators are cold at the bottom and warm at the top.
Assuming this is the correct diagnoses, would a flush cure the high pressure and resolve the issue with the expansion valve?
I don't want to throw good money after good money - I just want the correct fix.
