No, you're not.
And I don't think you ever have that I can remember. You read my comment backwards somehow.

Re: Best Type Check Valve for DHW Recirc System?
@srhodeswv I remember speaking with you on the phone, glad everything worked out for you.
Re: 2-pipe Radiator Experiments, parts 1, 2, and now 3 with insane reverse pitch!!
Thanks, Jake! Yes I’m aware of the alleged issues with concentric couplings acting as a “dam”, that is one reason I’m doing this, to see if it matters. So far, it doesn’t. I will be trying one pipe testing soon.
Even if it did matter, where can any of us acquire eccentric couplings? They are unobtanium today.
Finally, have a look at this photo below. Every section has the equivalent of a concentric reducer inside of it, yet radiators seem to work. This is a 1-1/4 outlet with about a 3/4” opening behind it, and every section has this.
Re: 2-pipe Radiator Experiments, parts 1, 2, and now 3 with insane reverse pitch!!
The effort you made is outstanding. Here is a correction to your experiment.
The discharge of the radiator in both examples should have been made with eccentric couplings.
Eccentric couplings would cause all the water to drain out of a properly pitched radiator.
The examples you posted are only for two pipe systems.
One pipe systems have steam and condensate entering and leaving the same port on the radiator,
I will post a discussion on one pipe steam systems that may clear up some puzzling facts.

Re: In FPHE separated water/glycol system, what is advantage of circulator on glycol "cold"/return side?
yes the HX could get a slug of even 0 degree glycol. So starting the boiler first may prevent freezing the A side. No issue with the glycol side pump on the supply side, either
This piping keeps the relief valve “seeing” both the heat source, and the expansion tank, it cannot be valved off.
The lower purge ball valve isolates the DirtMag, and one side of the pump.
Use the Webstone purge ball valves that allow you to purge from either side of the ball valve

Re: Curious about combustion analysis?
With that flame, I would definitely break out my combustion analyzer, draft gauge and thermometer. Something is wrong with that flame.
Have you looked at the heat exchanger with an inspection mirror? There may be a blockage in between the boiler sections .
Is the chimney drafting properly?
Re: No 1 Ideal Sectional Boiler from American Radiator Company on house built in 1926
UEi C155 Eagle 2X Combustion Analyzer Kit with Printer. It came with the original instructions. Your boiler should have a small hole in the exhaust pipe for the rod to fit. This is a pic from the internet on a newer system below. And the second pic is of the back of mine where the hole is located since we both have older more beefy systems. Yours might already have this back there.
A great HVAC youtube I enjoy is “Mikey Pipes”. It was actually because of him I search Ebay for my own combustion analyzer.
Hope this helps!
Re: Help over filled boiler
that’s the right one, or I should say “a right one”. Keep draining
If you are above the gauge glass then it will be several gallons to drain. Maybe 5, maybe more.
Did water shoot out the radiator vents?
Re: Swing Joint on steam main
This might be a better design, just keep everything sloping back to the boiler return.
Or perhaps a different trap will work.
Re: 2 Pipe Steam Radiator / Blower Unit
that is called a unit heater. make sure it has the capacity to do what you are trying to do with it. the motor can probably be replaced if it were to fail. the fan is probably controlled by an aquastat on the piping somewhere
