Hi I just bought a house on a private well that has been vacant for about a year. There is a whirlpool tub in the master bathroom and the jets had orange residue in them, so I cleaned it. I filled up the tub about an inch above the jets, poured Clorox Clean up with Bleach in and ran the jets for about 10 min. I have done this now about 10 times and orange brown flakes keep coming out. Do I need new pipes? Or is there something else I can try?
