Re: Best Solution for Connecting Copper to Iron Boiler
It was either a bad solder joint or some issue with the water quality in the system. If it has glycol in it, that needs to be maintained or it will become corrosive. that is why @pecmsg asked. Occasionally the potable water that was used to fill the system is very aggressive. If there are small leaks and a lot of fresh water being added to the system, that will cause corrosion. In a closed hot water heating system with reasonable quality fluid connecting copper and steel directly isn't an issue.

Re: Best Solution for Connecting Copper to Iron Boiler
Experience has proven to me that a brass fitting or valve between copper and black pipe is a great transition method. It causes the least amount of issues.
@bassman92 You can also use a dielectric nipple as a transition fitting.

We were "told" by National Grid that this was Federal Law pushed by the D.O.T. and that the rules were the same in all 50. Hmmm?? Mad Dog
Re: Oil Burner Tools
I think I still have a Nozzle Wrench somewhere. It has 3/4 and 11/16, with the 11/16 for the old burner bulkhead fittings.

The modern challenge is the rarity of common sense; very few possess it. And even fewer practice it.

Not original to me- I got it from @Firedragon .
Re: Replace B&G 100 or use Taco 007 monoflo
I called Taco and got two Senior Engineers on the line and told them what was done and one of them just went nutz! "I wish those F-ing guys would stop replacing 100s with 7-F5s!!!" The closest to the 100 is the Taco 0010 series. NOT the 007.
These two Senior Engineers are making statements without any facts. If they bothered to look at the pump curve for the 100, they would see that it crosses the curve for the 007 right at 10 GPM. If you need anything LESS than 10GPM, the 007 is going to flow more than the 100 at a given head. If you need MORE than 10 GPM (impossible on 3/4), the 100 is going to flow more than the 007.
It is impossible for the 007 to cause you to freeze if the 100 was perfectly fine unless you've got 1" or greater piping on a zone that has the capability of delivering over 80K BTUH (twice the heatloss of a typical 2000 sq. ft house @ 0°F).
I have serious doubts about the veracity of the story.

When it comes to common sense, it is extremely difficult to repair stupidity.
