leaking slant-fin boiler

Just checked out a boiler that is leaking between the first and second cast iron sections.  Homeowner wants to try and have it taken apart and fixed before thinking about replacing it.  I have busted quite a few apart on their way to be recycled but told him I have no confidence it putting one back together and thinking it won't still leak.  Anyone have experience?  It is a slant-fin, not sure if the sections have push nipples or gaskets.

    push nipples

    Is it really worth doing? I'd say probably not

    is that...

    a steam or Hot water boiler? If its steam you MAY have a  better chance w/ boiler sealer. I would give Slant/fin a call...

    Don't even bother trying to repair it

    with that much leakage, the push nipple has rotted out and the mating surfaces in the sections are probably damaged. It's scrap.



    Check with Slant/Fin to see if it's still under warranty. If so they will back it.



    Is this a steam or hot-water system?

    hot water

    Hot water.  Floor piping is polybutylene which might be the problem,  Am I right in assuming there is no oxygen barrier with polybutylene? 15 year old system

    oxigen barrier

    If you install another cast iron boiler it will get eaten up also.

    Install a COMPLETE stainless steel and brass system or use a heat exchanger between the boiler and the in floor tubing.

    Most PolyB...

    tubing was Non-barrier. If it is just grey non barrier . If it has a red coating on it then yes barrier. Your looking at a new boiler and some sort of HX to separate it from the ferrous parts...or going completely non ferrous. looks like a lot of money going into the system.
