Re: Dear Reader
Congratulations Dan! You deserve to take a break. You've toiled hard and have made a HUGE difference in our World. I personally want to thank you for making me the person that I am. Without you, I would not have had the wonderful career in hydronics that I had.. Thank you, TLM and your family for everything you've done. Unlike us, that knowledge you have imparted to our industry will live on for ever. Your legacy will live on forever... Thank you. Your friend in Colorado.

Re: Help draining a old steel expansion tank.
Take out the bigger plug that the drain screws into. The vent tube should come out with the bigger plug. The vent tube may be sludged up.

Re: Steam heat system fitting
I’ve seen this in an old book. Can’t recall which one. It’s a specialty tee that allows the steam to go to two floors. The object was to lessen the amount of returning condensate in either riser from the tee.
Re: 4 Story 1 Pipe Steam System
Yes it's that easy...mostly...but there might be venting on that top floor to quickly let the air exit the risers and you'd have to move that venting to the third floor. And then the boiler will be instantly 25% (more) oversized or so.
But also...yikes...that's a huge change...what part of the world are you in? I will now grab my 🍿 to watch everyone freak out
I assume one of the major reasons for this is so that tenants each pay for their own heating (and they get nice cooling)

Re: 4 Story 1 Pipe Steam System
It will work well enough. No real problem. Except... make sure that the mini-splits which you plan to install have enough electricity available to power them, and that they are able to maintain the required interior temperature at the design temperature of your area. They may struggle to do that, Or just no.t work at all...
Re: Sizing a circulator, general questions
I never left the office to look at a job without my B & G Wheel
Weil McLain WM97+110 Gas-fired water boiler not thoroughly heating
Hot water wont circulate completely around my baseboard. The pipes are only hot for about 20 to 30 feet past the Area Control Valves.

Re: Sizing a circulator, general questions
A very handy tool, the System Syzer
Here is the EL chart from the manual version of the System Syzer.
A 5 gpm example showing the velocity and friction numbers as the chart above.
