13 gal kitchen trash can filled from the bottom of the WH, with a short hose, about 10 times until the water cleared visibly. Then from the trash can each time several 2 gal buckets carried the few feet to the washer to empty that trash can. Each time turned the new water valve on to stir up the water remaining in the tank. I did see it visibly clear each time I drew water off into the 13gal trash can. So I figured something was improving. Later I took a large clear class of hot water from the sink. Let it sit and then later spoon stirred it up. I can't imagine it being any clearer than it was.
