Re: Boiler/Baseboard System - Pump not always running
Hello @lilweezy29,
As previously mentioned as long as the thermostat is calling for heat the circulator should be running. Observing the system and/or testing with a multi-meter may help discover why it is intermittent.
1. Thermostat closes (call for heat).
2. Relay coil 'CR' is energized.
3. Relay contacts CR1 and CR2 close, simultaneously energizing two isolated circuits.
3a. CR1 supplies power (passing through the limits and safety controls) to the Damper.
3b. CR2 supplies power to the Circulator (energized it continuously).
4. Circulator is running (continuously) and the Damper opens.
5. When the Dampers opens all the way and the Damper End Switch closes and the Gas Valve is energized.

Re: Circulator Pump size and Qty
I think what you saw on left is the big black insulated box. I think for air purge ?
I am not sure the answer to most of the other recent questions

Important to use a single run, no splices.

Re: Meaga press for steam
Mega pressed joints have all kinds of rotational movement in them after they are pressed. Its way more than a threaded joint . Some can get 10 to 15 degrees.Threaded steam joints have no movement in them. Anyone who has tried to remove a fitting knows this!
kinda scary how much. But they dont leak.
Re: Some rads hissing, some not
I’m wondering if I should just try putting a half way decent air valve on one of the whistling rads to see if it does anything, but I also don’t want to just start throwing parts at it.
Re: The case of the tripped auxiliary low water cutoff, this weeks case
My shot: Oil was introduced into the boiler water from new pipe work and this caused surging with a sudden drop in water level that triggered the manual reset--when examined after the fact, everything seemed to be in order. They would have had to be watching the gauge glass at the time of the surging to see it occur.
Re: Radiator Ball Valve?
Some of those cheap valves can be made to stop leaking by tightening the nut that holds the handle on. If you run out of threads try adding a washer between the nut and handle. If that does not stop the leak, replace the valve.
Re: Radiator Ball Valve?
The cheap ball valves have no packing nuts. I would just cut it out and sweat one in .
I don't think you really want to do that on the fly. You could buy a decent threaded ball valve and put 2 compression adapters in it.
With the adapters in a threaded valve it might make it long enough so that you can cut the old compression sleeves off and slap the new valve in there.
