Hello. I have an Potterton Puma combi boiler about 10yr old. Just recently
without running the CH it is losing pressure, 0.1 bar every few days.
Expansion tank pressure was low - pumped up tank but still same pressure loss. Does this mean I have a leak in the CH system ? Can't see any leaks from rad valves. Can't access all plumbing under the floor
very easily. Thanks
