Will I have bigger problems when I try to loosen my galvanized pipes?
2 Attachment(s)
Home is 24 years old. Well has some copper, some PVC and some galvanized pipe. I have a leak just past where the pipe comes out of the tank. It seems that a galvanized elbow is leaking THROUGH the pipe wall. I don't see leakage at the joints but it is dripping at the bend in the elbow. Is this possible that the wall of the pipe is corroded through?

Now, when I remove this will I find that the threads are corroded to the point of causing the job to get bigger?

P.S. I just went down and took some pics (aren't those digital cameras something). It looks like just as I suspected, the pipe wall is leaking.
Also, notice the joint where I drew the arrow. It appears that the pipe with the outside threads has been threaded inside to take the short pipe. What kind of problems do you see here?

All recommendations appreciated.

Is it hard water? Sulfur?

Yes it is somewhat hard since we need have a water softener. As you can see on the valve handle, there is corrosion.

Sulfur water is especially corrosive to copper and galvanized pipe. That's why the copper in your picture is turning green and the galvanized is corroded. Best thing to do is replace all that you can with PVC. Or you could replace with Galvanized and it might last another 24 years.

But yes, it looks like you will need to replace most, if not all of what is in your picture.

The biggest problems are all the dissimilar metals. Leading to galvanic corrosion and electrolysis. I would replace it all.
