Re: New boiler - pipe noise / surging
My theory is the squick collected a bunch of the chemicals and a lot of it is settled at the bottom. Boiler fires—>stirs up that muck—>a fraction of it escapes and settles at the top in a fat layer/causes surging—>most of it settles back to the bottom. If this theory is accurate, I'm hoping a ton of skimming will eventually help.
Your theory might be accurate. And, if so, to remedy needs the capability of draining the bottom of the boiler. Note that you have an elbow at the point where the equalizer reaches the bottom of the boiler. This should have been a Tee with a pipe nipple and a ball valve to allow you to drain the bottom of the boiler to remove this material.
Skimming will not help as the material does not float to any degree that will remove it.
Re: I need a new tank due to rot. Is Roth the way to go?
@Leonz: The reason I am saying your comparing the cost of the cleanup to the cost of installing a specific brand tank is flawed, because it presents the dilemma as if those were the only 2 options.
If we want to stick to the theme of this thread, the scenario we are discussing: Assume the decision was already made to replace an existing tank. Given that, it is fair to take the cleanup off the table.
Accidents, doomsday scenarios equally apply to any brand of outdoor tank, so those can also be taken off the table. The discussions (should be) about : should the replacement tank be a Roth, or maybe something else.
I propose that most of the residential storage tanks are inside of the house. If that option is available, it is IMO preferable, to avoid problems with: extreme condensation, weathering, outdoor specific risks such as colliding with some vehicle, visual appeal, flow problems in cold weather, the extra cost of site prep… etc.
Re: ECM blower manufacturer's cfm table accuracy
surging.
with excessive static. Beyond what the ECM is designed for it spins faster and faster eventually causing the blade to slip. That drops the static for a moment then it corrects. All this up down drives the motor slower faster several times a second.

What is a fan surge?
At a certain moment, the fan will not be able to deliver the required flow and pressure in which case the fan will surge and the airflow direction will reverse. The system pressure will decrease until the fan recovers and the process will start all over again. This phenomenon is called surging.

Re: ECM blower manufacturer's cfm table accuracy
Sorry, I was thinking about vane axial blowers. I just swapped the motor out on a 10 ton rooftop, that's what it had. I always got to stop & think about which type of blower I'm working on, to figure out how it responds to static etc.
Re: Gas fired boiler no heat
Keep trying. Release the depressed pilot button as if you are in slow motion. Sometimes you need a few tries before it will light. Again…slowly.

Re: Strange oil burner operation
Even if it isn't the cause of the problem, you should replace the crappy R8148 primary control to a modern digital primary control with interrupted ignition and a 10 or 15 second trial for ignition.
In 2025 no oil burner should be operating with a constant spark primary control with a 45 second trial for ignition.
I recommended the Carlin 70200 set for 10 second trial for ignition and interrupted ignition. It also has diagnostic features that will assist with troubleshooting problems.
Re: Liner with oil heat?
When you disconnect that vent pipe from the Mini Stoker, think about adding a 7" RC Barometric draft control.
It is recommended by the boiler Manufacturer on page 12 and 13 of the Installation Manual.
Re: Faucet Washers
It isn't entirely clear what the ones you get from a hardware store of home depot are, they hold up ok but when they go it is because they are deteriorating from being in water, not that they are wearing out. Teflon doesn't deteriorate and works great in service valves but takes a lot of force to get to seal in a faucet that is used regularly because it is fairly hard. The seat is fine. I just want something that lasts more than a couple years. I don't think that the moderately high chlorides in my water are helping anything.
Danco offers 2 "grades" of washers but doesn't say what material either is. The general purpose ones from Mcmaster Carr are buna n.
Both Buna-N and Neoprene are acceptable but not great for water. Teflon is great for water but too hard. EPDM is softer and excellent in water. I couldn't seem to find them premade but maybe @hot_rod has a source.
