Recently when Central Heating has been running for a while there is a very loud noise coming from boiler. I think it could be the pump? Is this right? Its got a GRUNDFOS Up 15-60. How easy are these to get hold of and replace?
easy to get from parts center etc and pretty straight forward to change, isolate flow and return to boiler and drain boiler through white drain off far bottom right.
you can get a worcester multi pump head to go on rather than fos , a few quid cheaper
