We bought our current house in 2011. It was built in 1967, and is not in a subdivision. We live at the highest point in the county and have a 250 ft well. The first year our well supply line broke and we had a plumbing contractor dig up the front yard to replace the supply line from the well head to the pressure tank. Since then we noticed a bad smell and black silt from the hot water, and Lowes told us it was the anode rod in the water heater, so I took it out and capped the access. Didn't help so we chlorinated the heater after draining and letting it refill. Still got the smell. So we replaced it with a new 50 gal power vented heater, had a water systems company replace the softener and install an RO in the basement just for the kitchen sink. Still get the black silt and smell from the bathrooms (3 1/2) for a few seconds when first turned on.Water systems company cut the anode rod out of the new heater. Basement is plumbed with copper to the supplies and sharked to pvc. (shark bite, gator bite, whatever) That was eight months ago. Had the water systems company back out again but of course no black silt while they were here but next morning it's back. They said it may take "a while" for the pipes to clear out, but eight months?? I pulled and cleaned all the faucet aerators. Has to be somewhere between the new filter/softener and the faucets. Or maybe a smaller micron filter in the softener?
