Re: Dirty hot water, boiler overfilled, related?
Sounds like the indirect coil is leaking.
What I would do is mark the boiler water level with a sharpie and drain and shut off the indirect tank before you go to bed.
In the morning the boiler water should not have moved, or it could drop a little as it could be leaking back through the indirect as the indirect now has no pressure on it.
Re: “Polished” cast iron radiator finish
Cast iron is very brittle and can not be polished .. Powder coating for the polished look is your best bet .

Re: AO Smith Gas Water Heater Warranty Replacement
Yeah i just can't wrap my head around charging a handling fee to replace a water heater under warranty when you sold the original equipment, it's just not customer friendly at all. seems so clear that 90 was leaking, just fix it and keep the customer happy, clearly an install error.

Re: Slant fin oil boiler
Doubt that it is something major. It maybe they just need an adjustment. Since you are almost due for service in November why not have it done sooner. Tell your service provider so they are aware of the issue.
Re: Combustion air for cast iron boiler
my understanding was that if it had overhead door that a vehicle could be stored inside, a flame needed to be elevated 18”
We did this with water heaters in garages or with attached rooms until the flame protected style water heaters became available
No harm in checking with the current codes in that area. Stay safe.

Re: House is Overheating
I believe that what you’re calling “diverter valves” are actually zone valves.
The aquastat does not control these, the thermostats do, and their end switches turn on the pump control and that turns on the boiler.
Some better pics from further back that encompass the boiler, its near piping and controls may be more helpful, but diagnosing a control issue requires a multi meter and the knowledge of how to use it.

Re: Radiant heat with oil? Can it be done?
Nothing wrong with my knowledge and experience. Explain to me again how it won’t short cycle.
Especially oversized, shoulder season, ODR, multiple zones.
In any of the above mentioned conditions, even with P/S, the boiler is bouncing off high limit in a minutes.
I gave the best advice on best practices. Again, feel free to do an inferior job. Your customers won’t know any better either.
Re: My three worst jobs sites. What are yours?
Sewage treatment plants it is true after a while you don't notice the smell as bad………..until you get home where there is no smell and figure out the smell has saturated your clothes and into your truck seats…..and your skin.
