Hey All,
I have come on for some advice from those in the know. So first up, my Junior is in need of a service. It has been two years since I last got it down to Chris at Talk to give it a look over. The Problem is, i now live up on the Murray (in Mildura) and I only tend to get back to Melbourne for short visits. I have turned to my own skills in recent times for minor fixes, recently the anti-vac valve went and i was able to replace it without problems. Things seem to be running fine, but for the fact that when my junior hits temperature I can hear a slight hissing/sizzling sound as if water or steam is escaping from somewhere, I am not sure what seal this might be any advice where to start looking?

Thanks in advance,
