So in taking my radiators off the wall the TRV now spins on the pipe and is leaking from the bottom nut. It doesn't seem hugely difficult to replace as long as I drain the system. I have 2 questions:
1) I have removed 3 upstairs radiators to paint behind them, before I drain the system will I need to put them back on the wall?
2) I have turned the stop **** off so no longer have any water (seems to have switched the cold off but not hot) do I need to do anything else to stop the flow of water to the broken TRV?
