Went through the whole gig. My two heaters are in series.

Drained the second, drained the first. Filled them both back up. Drained the second and flushed the second. Drained the first and flushed the first. Both showed clear water. Filled back up and turned the heaters back on. Back to brown hot water again. Cold is still clear. I’m lost.

Calling well dudes tomorrow.
