i have a glowworm combie but when i try to have a shower or wash down stairs the boiler does not have enoguh pressure to fire the boiler to make the water hot. it also happen,s that when we try to use the sink we have to run the tap on full pressure to try to get any hot water, the boiler is only a few feet away from the sink.any ideas chaps

If the cold water mains pressure is ok then there must be a filter on the cold water inlet to the combi , and that must be blocked . I assume you have not touched any valves etc before this started to happen.
