Also i didnt want to strip down a fire to get to a BBU at 7pm at night especially when it's cold and the dear old lady would freeze.. My first plan tomorrow is to phone up the manufacturers and diagnose the boiler fault over the phone with them, then repair it.
So rather than look at the boiler you have left the lady with no heating apart from the firefront?
How do you charge for these multiple visits and changing parts without having diagnosed that they are even at fault?
How do I charge? I don't charge.... Its for a friend after I've been grafting all day I popped in on my way home.
I work direct for a company. Stop assuming things. If you can't help, don't post.
