Hi,
Been on here before and Agile and Chris R were awesome for help.
Problem: Leak from inside the boiler. Looked like it was on the incoming water supply but I soon realised it was coming from the heat exchanger (just behind water incomer, on dhw side). Removed HE and found gasket had perished. Ordered 4 new ones so I could replace them all and did so successfully.
Unfortunately, when I filled the system back up and turned on the water supply, I had a slight drip coming from where it had been originally. Thinking it couldn't be from HE seals, I checked the incomer connection for tightness and eventually checked the gasket. That turned out to be in a bad condition so I replaced that too (1/2" fibre from plumbers merchant, and when that didn't work, actual part from Biasi).
Hooray, it stopped leaking! Until today that is. Removed HE to check seals were all in placeand that there was no surface distortion, and then reseated again successfully. I now think the HE may be physically failing. Is this possible? (welds seperating?). It doesn't look bad at all but I know water under pressure will find a way to escape.
At a loss and trying to avoid new HE.
By the way. I'm losing water as a drip every 2 secs or so.
Thanks chaps.
