I have 3 noisy TRVs as they are fitted on the return instead of the flow.
The instructions suggest this should be okay but they buzz as they close.
Rather than change ends (requiring 4 joints to be disturbed on each rad) is
there any disadvantage in rotating the valve to a horizontal plane - thus
putting the flow onto the 'base' of the valve?

Another thought - have the TRVs been fitted without ensuring the boiler
has a bypass route for when they all shut off?
Is there a radiator which doesn't have a TRV and can't be turned off
(lockshield at both ends)?
