Should lockshield valve be fully open?
Most lockshield valves have a plastic or metal cover. You should remove these and open all of the lockshield valves completely. This requires that you turn them anticlockwise. You should also fully open the TRVs (thermostatic radiator valves).
Why is my TRV not working?
If it’s not the pin that’s the problem, it could be that the wax or liquid capsule in the head of the TRV has failed and you’ll need to buy a new TRV valve head. If the pin in the valve won’t budge with the hammer, you’re going to need to buy a completely new valve – and you’ll need to drain down your heating system.
