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?


Beware they can't be wacked by a vacuum cleaner being enthusiastically
wizzed around.
