Could use some thoughts on this.
customer complained of foul odor and black sediment. no iron, .02 ppm Manganese, Coliform positive. Slight H2S hot and cold (tankless WH). Installed 75/25 mic filter, clack ozone unit (programmed properly, 9.6 GPM backwash button, 3/4 pex drain line, 1.5 CF KL, and 6gpm UV. Pressure tank is old but works fine and is at 40/60 with 37 psi. I normally clear the sediment from old PT by filling it for a couple seconds, drain, repeat till clear, then put the unit in service. he has no drain down on his PT, so I filled the filter housing with chlorine and bypassed the tank. I ran the tub and a lot of black sediment came out. it ran clear and I had him put the tank in service the next day. he's now complaining the black sediment is back. I see this as an impossibility that it's getting through the 75/25 mic and 1.5 CF KL. I'm thinking maybe it's KL? could use some thoughts on the subject. I should also mention he has galvanized coming from the well. He now wants me to sell him a PT.
