Hi, Can someone please offer some advice I am in the process of fitting a pair of TRV's to a bathroom towel radiator which I recently purchased from Hudson Reed. I have connected the TRVs to the towel radiator using PTFE tape and some bathroom silicone. However. the valves continue to leak. They do not leak at the olive were they are connected to the copper pipes (inlet and outlet). Can anyone please tell me what I need to do to stop the valves from leaking as this will be the third time that the central heating system will need to be drained down, in an attempt to fix the leaking valves. Should I be using plumbers mate instead of bathroom silicone to stop the valves leaking or some other form of jointing compound I hope that the i have been clear in my explanation. I look forward to hearing from you.
