Well, I guess I shouldn't have posted that here. I don't want to derail the thread, but I will answer your question. I have the sensor as far as it will go into the compression fitting. I will also say that I have a friend that has the same collector and his does the same thing. So, keep an eye on it. Maybe me and my friend got the only two bad ones. Not likely though.I'll have to keep an eye on this. How far in are you putting the sensor tube for the shutoff? Mine is about half way in.
Mine has filled twice so far (only had it installed a week or two) and the shutoff worked perfectly. Zero spills.
