I have to change a few leaky rad valves that tightening/packing the gland nuts hasn't fully resolved.
If anyone could be kind enough to fill in the blanks it would be most helpful....
1. From what I've read, a rad should have a lockshield valve and a control valve. Is this the same on all systems? My valves seem to be the same on both ends....
2. I want to fit one of the rads with a TRV. Am I right that I fit a TRV to one end and a lockshield to the other?
3. I'm reading conflicting advice as to whether the TRV/lockshield can go on either the flow or return end or the rad. Can somebody clarify.
4. For the rads not having a TRV fitted, are the valves fitted to each end the same type or is one a lockshield, the other a a control valve?
Any advice appreciated!
