Re: When to NOT use sharkbite? A question
I say the odds are greater by far that you will have a failure trying to sweat a pipe as a beginner as compared to a SharkBite installation.
I put a few 3/4" SharkBites into my system as a temporary situation, but now I am leaving there just to see how they do. Not one drip yet after 5 years.
This is totally anecdotal, but also anecdotal is all the fear mongering you will likely see in later posts in this thread against SharkBite fittings.
But I would wager that even for most plumbers they would see more sweat fitting failures than SharkBite failures.
Confirmation bias is a thing
Re: Did Everyone Get The TT Recall Letter?
One of the first things I do when I install or service a boiler is notate the serial number. Tech. support at most manufacturers won’t talk to you without that. One of the reasons is that different generations of boilers have different controls, thus different coding, different parameters, different parts diagrams…….
And then, when there’s a serious recall, I can spot the customers that need corrective action.
Part of the reason I can do this now is that I’m a small shop and I have time - usually in the evening or early morning - to make notations. I don’t think larger shops have that luxury or any incentive for future service work.

I mean compression fittings have been around for like 100 years.

Re: When to NOT use sharkbite? A question
There are places where Sharkbits are not just a good temporary fix (if the pipes are prepared well — square cuts and no burrs — they are a good bit better than temporary) but a perfectly valid permanent fitting.
I've use them, for instance, in settings where I am doing domestic water — and am MUCH too close to highly flammable wood to even consider heat, never mind a torch.
Re: Oldest Boiler
30's or 40's? the newest patent dates are the late 20's. did you have gas available in quantities for heating that early?

Re: Oldest Boiler
The oldest that boiler could be is 1928, as is says “manufactured under one or more of the following u.s. patents” on the plate and references the (newest) date “July 31st 1928”. Still old!

Sharkbites are a temporary, emergency fix, but this is America...you do what you want except gas work or anything that could contaminate your local drinking water Supply..Don't worry, if it blows out it blows out.Only water Mad Dog
Re: Did Everyone Get The TT Recall Letter?
Yes…We received the letter
Yes…Although we did not Install ANY of these boilers we keep all the serial numbers for all the boilers in an Spread sheet.
Yes… We are contacting all the Customers with the affected Boilers to keep them safe as a responsible Contractor should do…😉
Re: When to NOT use sharkbite? A question
@JayPoorJay Shark bites are made for your situation. The homeowner do-it-your-selfer.
I have found them to be a great transition fitting and have used them myself from time to time.
Simply follow the directions on how to install them.
The first thing I would do is install a couple of valves on the hot and cold lines to isolate this area from the rest of the house. 🤔😉

Re: Oldest Boiler
My brother lives in an old apartment building in Oakland. The building has two-pipe steam. Not very well maintained of course.
