Corrosion on Return Piping

Dave_in_Mpls

Hi Everyone -

We are dealing with a steam boiler that was installed about seven years ago and the return piping near the boiler is extremely corroded. What is the cause of this and, other than replacing the piping, how can it be rectified?

Thanks in advance for any help you can provide!

Leak?

That looks like it has been leaking for a while, probably very slowly. Is that the return line, try to back up so we can see more of the boiler and that piping.



 Do you know how often it feeds fresh water into the boiler? If the automatic water feeder, or

you, are adding water more than a couple times a moth you have a leak. that's one reason I don't like aotumatic water feeders unless they have a counter on them.







When you blow down the boiler (to keep the LWCO clear), what does the

water look like? Also have you drained any water from the mud leg to see

what the water looks like?



Getting that pipe out maybe quite chore and with heating season upon us you might want to have a pro deal with that unless you have the tools to deal with removing a broken stub from the boiler without cracking something - one crack and it's all over.
