Hi,
Looking for some advice please.
We need to initially cap and then replace some heat convectors which are leaking from pin hole leaks in the tube. They are currently closed on the thermostat and produce 3 single drops a day.
They have a Herz valve for 2 pipe system which looks like the picture attached.
1. For capping purposes do you only cap the opening opposite the thermostat head (2) or should both openings be capped (1 and 2 in the diagram)
2. We live on the top of a block of shared flats and may not be permitted to drain the whole system down. Is it possible to do this without draining down the system like I've seen with standard radiators that have valves on either end? - we should be allowed to turn off the pressure pumps. I understand this is not the ideal scenario to do this but as there is no significant amount of water above us would it be doable although messy.
Thanks for your help
