    Stop leak in a boiler?

    We have a Weil Mclain boiler with indirect, seems like a leak in a boiler section. Any reason not to use stop-leak product in a boiler that is connected to indirect hot water heater.

    Probably just a bad seal between sections. Stop leak won't hold it for long. Best to have seal replaced.

    How many times must one fix something before it is fixed?

    Can I replace the seal or tighten? I've been told that the whole boiler would need to be replaced. (note it is installed in a very tight place)

    DO NOT USE ANY PRODUCT HAVING PETROLEUM IN IT IN A WEIL MCLAIN BOILER. The section o-rings will fail literally over night. If you've got a leaker, replace the boiler but one small leak is one thing but Stop-Leak will have the entire system of hydronics on the floor within hours.
    If YOU want change, YOU have to first change.

    If you are waiting for the 'other guy' to change first, just remember, you're the 'other guy's' other guy. To continue to expect real change when you keep acting the same way as always, is folly. Won't happen. Real change will only happen when a majority of the people change the way they vote!

    Please explain what you mean "but Stop-Leak will have the entire system of hydronics on the floor within hours." Hercules the maker of "Liquid Boiler" said they have had lots of success with the product stopping leaks for years.

    Is it a cracked section, or just a seal that is leaking.

    Depending on its age, still under warranty. And WM will send a new block, or just a section.

    The boiler is about 15 years old - still under warranty?. Whats the best way to determine if it is a seal or a cracked section.

    There is a warranty on it if its a water boiler.

    Has to be inspected/checked to see if its a crack or seal leak. Not too had to do.

    I did explain. The seals used by Weil McLain between their boiler section will be damaged by petroleum based sealers. It's in all their literature but you don't have to take my word for it. Just use the sealer and the o-rings will dissolve overnight and the system will drain onto your floor.
