Our five year old Mexico HE36 gas boiler needs yet another auto air vent valve. It was replaced in the final months of warranty due to it leaking and dribbling water onto the electrics causing the trip to go. Parts Centre are the only stockist I can find that have one, and one only! Is in the Portsmouth branch but they are sending it up to me "next day" delivery for four quid postage. That's not bad as it would have cost more then that in diesel for me to have driven to the nearest branch
Anyone else aware of this being a regular failure on these boilers?
