Hi - been checking the airing cupboard and found the isolating valves either side of my CH pump (28mm) have scale and rust build-up around the lock screws in the brass fitting - should I be worried about this? Best way to get rid of it?
Also, a gate valve (isolating the hot feed to a shower pump) has white limescale build up around one lock nut. Should I just clean this off and give it a quarter turn?
No leaks detected.
Thanks
