Been called out to leaking Isar 30HE coming from the plastic body of the diverter assembly at the DHW outlet - from what I can see - not a lot of space in there! Boiler working fine, no pressure drop, leak stopped when isolating cold water inlet to boiler. Removed copper elbow and replaced 'o' ring but still leaking. MI's don't list that part unfortunately. Wondered if any of you more knowledgeable and experienced folk had come across this issue before and able to shed some enlightment - are these plastic bodies prone to cracking? Your help is much appreciated...
