house pipes & iron oxide -- a 50-cent solution

If I understood the original post the concern was damage to pipes or
blockage of them. I sugest going in the opposite direction, acidify.

The basidity of baking soda will help to precipatate out any iron that had
gone into solution. The particles can then be washed away or picked up by a
soap or detergent (both soap and detergent only work in basic condions
anyway, thats why baking soda is a londry boost)

If you want to get rid of any ferric oxide that might have built up in a "J"
trap or a low spot in your pipes try a mild acid wash. Nether vinager or
citric acid will hurt plumbing and will reduce the ferric oxide (water
insoluble) to a ferrous ion ( water soluble ), which can be flushed out with
running water. Its the same idea as running vinager throught your coffee
pot to remove metalic salt deposits or running your dishwasher empty with a
couple of packets of Lemonade flavered KoolAid (citric acid) in it to get
rid of rust stains.

I also would like to sugest deferring your question to a higher source.
Depending on the type of water you have in your area, your local plumber
should have some good ideas on how to control iron deposits.

I hope this helps
