Thanks in advance for any help.
Issue -
heating comes on. pipes tap loudly. the noise is a fast tapping, slows down and then comes to an eventual stop.
The noise does not originate from the boiler but from the pipes close to the boiler and the first 3 radiators (and their pipes) on the system. (boiler upstairs - no tapping downstairs)
Worcester-Bosch combi boiler (5 years old)
system flushed on installation and magnetic filter fitted
tried so far -
radiators bled.
radiators bled a 2nd time after system switched off for 20 mins.
boiler pressure adjusted from upper green to lower green to central.
