thats why flushing sometimes causes brown or cruddy wate

Hi Hallerb,

Ah. Yes. When the water was turned back on, there was a lot of sputtering
and shuddering going on, mostly sputtering. I thought it had to do with the
new burner.

But, this shaking & flushing of the pipes must have shaken loose sandy
grainy "crud" as every galvanized pipe I replaced was almost clogged
completely with what you called "scale".

The water *was* brownish for a long while (you can see that in this photo
even after cleaning out the showerheads, so the crud was *still* coming
through the lines even ten minutes after initially turning the water back
on!

I guess all that brownish was sandy grainy stuff that caught in the filters
of *all* my faucets, showerheads, and dishwashers!

Nobody warned me about that so I'm *adding* it to the how to that I wrote
up!
