We can see the licensing system working as designed to disallow competent installers, and allow incompetent ones…kind of depressing
Re: Vaporstat shelf life?
I have taken apart a number of vaporstats. I dropped them and hit them [Old and new] to see if they would fail or give bad inaccurate operation. They did become inaccurate and had to be adjusted but did not fail. They are basically well built. As previously stated, High number of cycling off and on would be the most likely cause of failure. I just remembered that a vaporstat in my building failed because the person who installed the heating controller was controlling the steam cut off by a relay trigged by pressure from a vaporstat. This meant that the vaporstat was tripping 18 to 20 times a day during the winter season.
Re: Heating not working in the floor where the distribution system was changed
Are the grey PEX lined purged?
When you purged all the white PEX lines and you got water to flow thru each one, did you do it at the opposite end of the gray tubes? If there is still some air in the other grey PEX line (the one you didn't use to purge the white ones) then the circulator may be pulling at air in the line.
Re: Heating not working in the floor where the distribution system was changed
You might hook a garden hose and blast all the loops with high Flow/ pressure
Isolate the manifold from the boiler if you do, it cannot handle over 30 psi

Re: Heating not working in the floor where the distribution system was changed
Unfortunately, those manifolds don't allow you to purge loop by loop as there are no individual valves on the loops. And you can't use the little bleed valves at the manifold to purge air in the piping. You need a high volume of water to purge both the grey tubing and all the white tubes and it should be done with the proper valving at the boiler.

Send you advertising about competetive fuel oil dealers. Or perhaps kidnap your wife and hold her for ransom until you pay your past due oil bill from two months ago. Or give up all your state secrets. be careful, theNSA is watching everything!
Re: Trane Vapor system?
First thing to do is change that vent on the dry return. It looks like a Hoffman #75- use a Gorton #2, and I bet those end radiators heat better. Also, are there any vents at the ends of the steam mains?
Re: Trane Vapor system?
And the second thing is to install a vaporstat set at 8 ounce cutout and 4 ounce cutin…
