I had the same problem, this is the solution I just used. I called a plumber told him I wanted to run two things through my homes water pipes. First we ran 100% vinegar in all pipes let it sit for 15 minutes, it foamed and dissolved all mineral deposits. Then we did the same thing but with 100% clorox bleach again let it stand in pipes for 15 minutes, this was to kill any bacteria that was in pipes. You should have seen the amount of green and brown residue that came out of all faucets. After we ran cold water for 10-15 minutes to clean all solutions out of pipes. It appears to have worked great. 20.00 in vinegar and Clorox, and 2 hours plumber labor. I am now a happy camper.

Hi Mike and welcome to The Plumbing Page on AMHD.
You piggybacked on a 3 year old dead thread so I gave you one of your own. Before you post look in the upper left hand corner for the date.. Thanks for the update and kudos for flushing your lines by yourself. By the way. You never said if you were on a pump or city water and the type of pipes that you have. Were they old galvanized? Cheers, Tom
