    Roughly speaking, one foot of wrench for every inch of pipe size.

    Why has this header suddenly started leaking, and from where?
    I can't believe there is a rust hole in it, so is it leaking at a threaded joint-maybe from over pressure?
    Maybe cranking the pressure down will stop this.
    Ridgid makes a compound leverage wrench which might help get things apart here, although it is easily as heavy as a 6 foot conventional!--NBC

    5ft wrench for 6" pipe. The wrench is brutally heavy. I can never seem to make a chain-wrench work correctly. While putting the new pipe and fittings together, definitely use lamp-wick, teflon tape, and dope.

    Can't you rent those large breed dogs? Unless you can bury the cost of the big dog in the job, you'll never use it again. Tool rental places rent everything you can imagine.

    I've been shocked at what some professionals rented that I laid out the cash to own. But I used them and had them available.

    Those compound wrenches are quite the silvery sheckles to own for a one time use.

    Is it easier to cut and use flanges or compression couplings?

    5' pipe wrench can handle up to 8" pipe. As jstar said they are brutally heavy about 65lbs each one and you'll need two of them.
    Not so fun piping it all together but once your done you'll feel like you've had a good workout and satisfied of the work you've done.

    I try to avoid threading and wrenching anything over 4". I've been able to do up to 8" headers all welded, with threadolets and/or cut and welded nipples as necessary so I still have the swing joints i need. For 6" I use a set of chain tongs, which as @JStar‌ mentioned can be a pita sometimes to get on tight.

    I have no doubt some guys would have piped that using a 2" header.

    That, is awesome work!

    You are most certainly right about that. The old single boiler was way over sized and only has a 4" header.
