Point#3 about the 10mm hot water pipe is the most valid point for me. It indicates that the guy is a cowboy and in your shoes I would be checking his credentials with Corgi. If he can't do the water side of the job competently I would be concerned about the gas side of the job whether his credentials check out or not![/quote]
Indeed! Like I said, two of his compression joints were leaking anyway, had to get him back for that - the 22mm CH feed pipe was actually loose by hand - nut was really tight, must have had a duff olive or something? IT does raise concerns about the gas side tho, good job I don't smoke innit...?
Incidentally, why does the condensate drain have to be insulated? He's done it in (approximately!) 22mm plastic, and it runs through the wall and to a gulley about 3m away. Its not insulated (suprise).
I rang Ravenheat this morning to ask about the flue angle, 10mm water feed, but being a mere non CORGI regd member of the public they wouldn't discuss it with me. Told me to take it up with the installer - D'oh - like he's really gonna admit its wrong!
Thanks for all the info lads, its very helpful.
