My water softener is shot,I will be replacing it,and have it bypassed at this time.I found the problem by finding rust and little balls in my water one morning.I didn't know at that time what it was,and I ran water until I had no more balls or rust.I still have a few faucets,washer,that I have not done this to.I now know it was probably not smart to do this.how can I clear out the remaining lines,and,what type of damage,if any,may I have already done?
