Re: Steam Near Boiler Piping
Length of the orange nipple does not matter. Anything goes below the water line. As far as combining the 2 1 1/2 returns into 1 that is fine as well.
The overhead returns carry steam and water, so they are larger when you drop below the water line they are wet returns and the smaller pipe is fine.
Should work well Congrats.
Re: Calculating head in primary loop and recommended replacement circulator
I suspect there are many over pumped systems out there.
If you trust the numbers from the man and @HydronicMike 13 gpm range, less than 5’, then a 0014 is way off curve for the job
Over pumping leads to high flow velocity, which often presents as noise. Does the boiler short cycle, on and off a lot during a load?
Check the delta across the boiler S&R to get an idea of actual run conditions.

Re: New press
@PC7060 Yes, but the rings get you out of a lot of jams. With just the tool, you can only work on one plane; the rings offer innumerable angles.
Re: Issues with steam system after work completed
I think I figured out a good comparison.
We decided to remove your sewer line and not replace it because it's too difficult, but it's ok because we installed a bathroom fan.
The boiler is piped correctly because someone else did it.
Please call the guys others listed above.

Re: Steam Near Boiler Piping
" My plan would be to combine both return lines (both 1 ½”) at the ceiling and drop them down to the Hartford Loop. Would there be any issues combining both of the returns to one at that point in the system? "
NO !! If this is a 'One Pipe' system the returns should be connected way below the water line at the wet return level. You need steam isolation at the end of the returns.
Youtube, the "Silent Steam Team" videos, many example installs. Looks like you are trying to build it like the manual shows, Good !!!
Is this a 'Close' nipple ?

Beautiful cleaned up American Radiator
Been a while since I posted, but mostly as it’s been a while since I needed to (or unnecessarily chose to) work on our system… but as I’ve fired things up for the first time this year, felt like a good time to get a picture of the beautiful American Radiator beast I bought, cleaned up, and installed last year.

Re: DIY boiler supply leak woes
I didn't let myself believe it wasn't going to leak for at least two weeks. @Intplm. your realistic and clear-eyed description of just what I might be facing (and, I think, accurate guess about what the plumber might have been thinking) helped a lot. And thanks everyone else too.
Re: New press
The larger tongs (1-1/2 - 2”) are heavy and make the tool front heavy when used. The pistol grip is better in that scenario. But the barrel grip is better for tight spaces. You decide.

Re: Hot Water Recirculating system?
Hi, The gold standard in my opinion is the ACT Metlund demand system. It does what @tim smith did and has remote push buttons and temp sensor to tell the pump when to turn off. It saves around 90% of thermal losses. At the other end of thngs, a well insulated gravity system can work, but some old timers taught me to drill a small hole in the swing check, as gravity might not open it.
Yours, Larry
