noisy pump in CH system

Postby dajome » Thu Oct 23, 2008 5:58 am


I have a noisy pump in my combi boiler - sounds like air in it - any views on how I can get it out - trying to get hold of a heating guy at this time of year is pretty hard and I'm sure it must be a fairly simple job.

Check the auto airvent on the boiler is open. Vent pump by undoing large screw on the pump head to allow air to escape.
