So long as the entire post rests on the footing, you should be alright. But the post mustn't overhang the concrete.
Re: Pinhole in 40 yr old copper
Agreed Just sitting on concrete is a recipe for disaster.
Even a short piece of PVC prevents that.

Re: Pinhole in 40 yr old copper
Is the copper in contact with the cinder block or concrete wall? If it is you might put some Armaflex pipe covering to space it away from that. Don't have to insulate the whole thing if you don't want to. just cut some pieces as stand offs. Other than that copper is pretty rugged but things happen.
Re: Gas boiler heating house without call for heat
Yes, with the flow control manually opened the hot water will circulate by gravity. Closing the valve should solve this problem.
You shouldn't need warm start as you have a separate water heater.

Re: Flash light and batteries
I've replaced a bunch of AA with rechargeable LiFePo4 cells. These are 3.3V nominal and can replace any pair of AA with a jumper wire. The mAh is not that great on them but they don't self discharge like NiMh.

Re: Dunham valve rebuild?
Very likely has crossover traps from the mains to the dry returns. Please do yourself a favour and learn how the entire system was set up and operated before you work on it.
Re: Flash light and batteries
Hi @EBEBRATT-Ed, You bring up a good observation. I've had tools ruined by leaking batteries. It would take getting used to, but how about not keeping batteries in tools that you don't use everyday, but keep them separately, maybe bagged, in the glove-box or elsewhere and install them when needed? I know it's a cumbersome idea, but it's no fun to have a good meter or other tool ruined. Maybe someone has another approach?? 🤔
Yours, Larry
Re: She canna take any more, Cap'n! She's gonna blow!
One thing I forgot to mention is that if you keep the tank, you can NOT have any means of air elimination on your system, because it WILL get rid of the cushion in the tank. I don't remember if anyone else mentioned that, and if they did, ignore me. Whereas if you switch to a diaphragmatic type of tank, you MUST have an automatic air eliminator. We haven't even talked about proper, ideal system configuration as it pertains to your pumps location in relation to the expansion tank. That in and of itself will create "air problems" in your radiators. Look up "Pumping Away" for more information.
