I have a 10mm microbore open vented Central Heating system with has traditional valves on all the radiators, I am looking to replace them all (except the one on the radiator in the hall where the thermostat for the system is located) with TRV's from Toolstation http://www.toolstation.com/shop/Hea...c+Radiator+Valve+10mm+15mm/d230/sd2762/p80954
The TRV's state that they are 15mm with a 10mm reducer so my question is does this reducer do away with the need for a 10mm olive? The current valves are 10mm so I plan to remove the valve and carefully cut off the exising olive and then fit the 15mm-10mm reducer and new TRV, will I have any problems with leaks from where the old olive was fitted as I do not want to have to replace pipework if I can help it?
