Where you're trying to troubleshoot a problem and every time you think you have it solved it isn't? And to make matters worse it just goes on and on and eventually you start dreaming up wild theories because you've exasperated all other rational thinking?

I mentioned in another topic about the steam appliance that a plumber and I were working on and how we worked together to troubleshoot why it was shutting down. After several attempts and returning numerous times to stare at this miserable piece of equipment we are back at square one. I've exhausted the electrical end and he's gone through the plumbing numerous times. Together with advice from people who understand boilers we've tried to figure if there's a problem involving that piece of the puzzle and it still has us beat. I hate giving up but I'm almost there.

Now, if someone can direct me to a boiler guru.....
