Bad Tubes
Last spring when I hydro the boiler I had some leaking tubes. I plugged the bad ones to hold the hydro test to 1000 PSI but know this was the end of the boiler. This is a welded tube bottom. By last fall I again had some leaking tubes. This past week I have been getting it ready to remove. Hear are some photos of the bad areas.
You can see all the rust in the burner pan.
