srvicing a back boiler!?

Not forgetting the flue flow test.

WPH. As others have said working on BBU is another kettle of fish and is not something I would take on without having seen it carried out a number of times by a good engineer and then being watched doing it myself. I will guarantee you will struggle for the first few times. I had a bit of an argument just yesterday with someone who claims to be able to do a complete BBU service in under 40 mins. Absolute utter rubbish!
