Re: Wiring - TACO SR501
Tha buzzing or humming is not an indication that the control is going to fail. You can most likley leave it there for years. (I tell my customers that the control just forgot the words, if you put the sheet music in plain view the humming may stop) Since you have been operating this way for ages, you probably do not need to operate the boiler for the circulator zone to heat. However if you have the rare occasion where the boiler does not have sufficient hot water to heat the circulator zone, you can use the additional relay contacts 5 N/O and 6 COM to operate the boiler with the addition of an Aquastat to keep the burner from operating long enough to make steam. Here is the diagram you might use for that. Place the Aquastat in a tapping below the water line set at 160°. When the water in the boiler reaches 160° the burner stops but the circulator keeps operating. 
Just an option if you find that you need it some day.

Re: Splitting a Rad
You would first have to find a supply house that still have a stock of push nipples because the odds are you will need them . The end sections are the most important I am sure you know.
Cut the pinch rods and use wedges to separate the sections . The colder the sections the easier the sections peel off . The work and care is in removing the misplaced or damaged push nipples . We used Permatex just incase to seat connections .

Re: Do sharkbite fittings work OK for radiant HW heating? Plastic pex A fittings?
I had planned on only using sharkbite fittings for the elbows under where the radiator pipes come down. That is to allow easier removal for badly needed new flooring or radiator painting some day. If they leak it will be obvious and they can be replaced. BTW i managed to screw up the sharkbite fittings. One pex pipe was scuffed and also one copper pipe.
Re: What is this?
Looks like an anti-surge tank which dries the steam. Last time I looked, a few small places still made these.
Re: Boiler running at high PSI
@JUGHNE, below are some pictures as requested.
This is going to show what a newbie I am to all of...how do I know which pipes are the steam mains?

Re: Boiler running at high PSI
Are there any air vents in the basement at the end of the steam mains?
If so what size/type....pictures.

This is the only vent in the basement coming off the main. It says it's a #5. I'm honestly not sure it works.

If none look for a fitting near the end of the main with a plug installed.
Or if you have return pipes coming to the boiler room, those may be the vent location.

Re: Replaced thermopile, voltage still too low
What else is in the circuit that may be creating resistance?
Re: Summer job stories
Yep..once they eat something bad...they are screwed! Asbestos...turned my favorite Thoroughbred Gelding El Bombay's face permanently white...took the pigment right out in two days after ingesting it in the stall when another horse 🐎 exposed it with a kick through the wall. (Few people realize how deadly and dangerous it is working around ALL horses, but Thoroughbreds are the most wild and unpredictable. Eating too much grain...My pop taught me all this. He said you MUST keep the barrel tops on of grain to keep rats 🐀 and mice out, but even more important was so that a loose, wandering horse wouldn't get in to it. A
Horse left to his own druthers will eat, and eat, and eat (thus the expression 😆 eating like a horse!) Till he keels over in pain. If you can't get him to pass it quickly, he will burst his intestines with the dry grain swelling and die! The last thing a Horseman will do is TRY to get him up, string his head up high over a barn beam, almost totally vertically (kissing the sky) and force gallons of mineral down his gullet, usually 😄 with some Scotch, Bourbon, even Rum water was left over from the night before.. They fought you less and got them tipsy 🤣 which relaxed them. This was no joke and the whole barn would gather around watch & help. If this morphed in to Twisted Gut, the last resort was invasive surgery. They didn't stand still for this or take it lying down, flipping out every few minutes and launching themselves airborne to try to get their tied up head free...1200lbs of Horse exerted tremendous force, thrust and torque as the broke halters and heavy ropes...what a seen. I miss my 🐎 Horses mad Dog

Re: Draining sediment from my indirect fire tank
Mine is piped the same way, cold inlet at the drain valve. At least you have another fitting with a valve on the other side down low. You will never get any sediment out of the valve on the inlet, all the water you get will be coming from the cold supply.
If the fitting on the other side at the bottom on the other side is not the boiler coil try it and see what comes out
I am in the same boat with my Bradford indirect, the only way I can get a good back flush is to shut the cold supply off to the tank and back feed the hot side by putting a jumper hose from cold to hot at the washing machine connection
