Due to the lapsed time, i do not have the paperwork but when i called BG to give them the opportunity to resolve, they confirmed that a powerflush was paid for and carried out - and yes, i do recall it cost a bomb. I dont recall it taking 8 or so hours to do, as the plumber who visited me said it should have taken?
I came off maintenance with BG because i couldnt afford to continue it at the time (they kept hiking the renewal price), but i shouldnt have to stay on contract just in case they didnt install properly in the first place, should i?
Cant be sure but think it was contractors to BG who did the work. Also aware that when things go wrong contractors always get the blame!
Also worth mentioning that since it was fixed, it has never worked better - i hate to think how much extra fuel it's been costing me! The filter needed cleaning twice a day for a week or so, now, 6 weeks on, there's nothing in the filter at all.
I'm glad a dim view would be taken - you obviously have much higher standards than the crew who visited me! 🙂
I know what you're saying, but I don't think there's anyone that will guarantee a flush after 5 years - I'll stand corrected now if there is - so I would be surprised if you do get a result. Perhaps a direct mail to the heirarchy would help? What's happened to you is really indefensible, I really do hope things get worked out for you
