Hello, my Ideal Isar was overpressurising so I replaced the expansion vessel - same problem - replaced the plate heat exchanger- problem solved apparently dhw going into central heating side..
I still have a problem though as the diverter valve is now leaking at the point where the dhw inlet/outlet pipe leaves the diverter valve. I've taken the pipe out by undoing the clip and put my finger into the housing of the diverter and what felt like a disintegrated o ring came out. The pipe came out with an o ring attached to it but my question is, is there also an o ring inside the diverter valve at the point where the pipe is slotted back into the housing? This would effectively mean there are 2 o rings together on this pipe with the clip coming in behind them pushing them in...?
I've bought an o ring pack but there's no instructions with it.
Thank you to any replies!
Regards
Jon
