I have 10 radiators with smart TRVs fitted to angled radiator valves - some of these valves are weeping around the plunger shaft - the valves were fitted in 2012 and 8 years seems a short life (I suspect they were cheap!), so I want to replace all 10 valves with better quality valves - but need advice & opinions for which make of valve will give long, reliable life.
Also, does the entire system need to be drained down? (I've seen some YouTube where some nifty work with a wet'n'dry vacuum cleaner negates this). Oh and ideally I need someone to do the job (Marlow, Bucks).
