Title: Brass fittings
Post by: timothy4140 on December 26, 2020, 09:19:22 PM
This past week I had my second fitting on my heat exchanger developed a leak, when changed it was paper thin as if it was sand blasted...
This is second time, first year or so ago, different heat exchanger...
Thoughts???

Something with the water, boiler side or domestic or both? Maybe try dielectric unions?

What kind of fittings are these? Is your pump way oversized?
I would collect a sample in a clear jar and let it settle and see if there is much sediment in it. if there is then I would install a filter.
If you haven't had the water tested recently, I would look into getting that done.

Were these fittings on the domestic side or boiler side?
I saw a HeatMaster unit with various fittings honeycombed thin recently. Turns out they were using some odd powdered water treatment. I think electrolysis was doing its thing.

Much like in a diesel I imagine. I have a sleeve out of a Waukesha that had numerous pits around the bottom ring and one made it clear thru the liner eventually.

This brought up a good question for me..Did I ground the boiler when I reinstalled it  ::)
Better check that tomorrow that would go some ways to reducing the effects of electrolysis.
I was half frozen to death when I installed this time and I have never even looked at grounding since. :D
