Orange/Brown grains coming in through water supply
We moved into a house a little over a year ago. This house has a water softener which we have never had before. This has happened twice since we've lived here. When you run the water or flush the toilets orange grains come through the water lines. They almost seem like salt. They are very irritating to the skin, almost burning. When this happens what I usually do is unhook the supply lines to the washer and let them run for 2-5 minutes down the standpipe. Then run all the faucets in the house for 2-5 minutes and it seems to be fine for months and then start again. HELP!
