Re: Can someone explain this hydronic loop heating.
I would use a manual bleeder. Less likely to leak in an area where they are not visible
Re: Help with Goodman GSXC16 Error code 04
Sounds like time to measure the voltage and current at the capacitors an calculate the capacitance to see if it is even close. 3 years seems about right for lowest bidder caps.

Re: What is causing this?
If it is glycol, that dark color often indicates the glycol has gone acidic It will attack the soft metals
I would flush the system, run a cleaner, then refill
If there are no pipes exposed to freezing, you may not need glycol
Those look like the older flow setters that you clamped a meter around to read. I don’t see a reason for check valves on the loops?

@jumper, Actually, it had (has) a thermostatic vent at each radiator return.

How old is the boiler/ relief valve? a new relief valve is cheap insurance

Re: Can someone explain this hydronic loop heating.
It looks like the air eliminator was eliminated.

Re: Gas shut off valve
Use caution if the valve hasn't been used in a while. You may want to loosen the nut on the other end to get it to move easier. This may cause a slight leak but will stop when you retighten the nut
Re: Gas shut off valve
That is the type of quarter-turn valve used to turn off gas. You will need a wrench to operate it.
As to whether it is the main or not, we cannot tell from the photo. Trace it back toward the meter; if there are no other branches that is the main shutoff.

Re: Trying to sell my steam radiators... Any tips?
Can you share any pictures? I would recommend listing them at a a very reasonable price but a price higher than the scrap value. This will optimize your chances of them going to good use.

option 3: run a new line along another route. What’s the frost line (depth) for your area.
