Hi, my boiler pressure keeps dropping. I am having to top up more than once a month which I know is not a good thing. I have had another problem with the boiler recently and last week the engineer told me that everything was OK and when I said that I had noticed the drop he just asked if we had any leaks.When I said 'no' he gave no further advice. The boiler is regularly serviced and we have no leaks at all in the system and apart from this pressure drop and the water upstairs not being as hot as I would like, no other issues with the heating.
Any ideas please...
