Im in my first year as a self employed gas engineer (three years wet plumbing) but i recently i have a had a few Boilers that are dead from the box, or pack up within hours. I fit Baxi 105's & DUO's normally but wondering if i should change to WB instead. As it stands i am currently waiting for Baxi to come out to a dead Duo 40 which has packed in within 8 hours of being turned on. This wont happen now till tuesday as its a bank holiday hence the customer is going mad and trying to blame me!!! Any of you oldies have this sort of problem ever??
