3/4 copper to male slip adapter
Working on the solar tank today. I needed a 10” brass nipple to make a clean connection
I drilled out a 3/4 adapter with a 7/8 holesaw, soldered it onto a piece of L copper
1-1/8 box fit perfectly

Re: Hot water boiler converted to steam, remaining return lines
Does it work properly? you should show us some pictures. I suspect someone bought the wrong boiler for a gravity hot water system and instead of converting the boiler or getting the right boiler tried to convert the system which almost certainly isn't going to work right unless they repipe the mains. You may have more work that you don't know about yet.

Re: Hot water boiler converted to steam, remaining return lines
Sure it wasn't originally a 2-pipe steam system?
Re: New boiler won’t heat house
Also, code requires that all materials be installed according to the manufacturers instructions. I have noticed that many contractors do not ever read the manufactures’ installation instructions, which is mind-boggling! Warranties may even depend on it (I’m referring to all materials, not just heating equipment.) I wonder whether it may be worth it to get a fresh set of eyes to come out and make the corrections and look over the entire install.If your contract says anything like "installed in accordance with the manufactures instructions", then your contractor is in breach of contract. He didn't follow the instructions.
Re: Which pumps do you stock on your service trucks?
No, Johnny NY, but I have them in the shop. We know how brutal the streets of the 5 Boros are on expensive stuff in the back of the Vans. Mad Dog 🐕
Re: Hydronic replace old boiler-gravity conv-2 pipe- Near Boiler piping and bypass?
I would order the dirtmag in npt and use adapters on the copper pipe because it is a very big chunk of brass and a little tricky to sweat and very expensive if you destroy it in the process.

Re: Gravity supply tank replacement
Also, if pilot has been on for years at a time, it has happened that the Tcouple will not function.
But you have to get the pilot lite to find this out.

Re: Trane Heat Pump with Gas Backup
6. Use it or Lose it. I'd run it at least once every two weeks regardless of the outdoor temp. No, you don't need to run it in the summer. It can sit all summer, and your furnace professional can deal with any fall start up issues. When you rest, you rust.

Re: Black Pipe Measurements
Best way to do an end to center is to make the fitting onto the pipe permanently. Then measure from center to the far end then cut the pipe and thread it. This does not always work with short pieces or nipples, but it eliminates 1/2 of any possible

Re: Injection tee spacing
Hot Rod. Your last drawings notes 4 x diameter, Interesting. Scrubbing is my piping slang 😁 as the injection flow is backwards to the building loop. I’m calling the boiler loop primary and the building loop secondary. Primary and secondary loops both have Grundfos pumps. Boiler pumps into a Calefi hydraulic separator.
