I end up using about 4 gallons. But I do let it run some after it turns pink out of the faucets to make sure the traps are protected. I don't go back and pour any more in the traps.

And I run some thru both low point drains and thru the black tank flush. Plus the toilet line. Seems to take forever for it to reach the kitchen faucet, both hot and cold. Don't know where those lines are routed but they must be long. Also takes a long time just to get hot water there.

And running it thru the hot and cold lines to the washer takes over a gallon if I remember right. I let it run thru the hot line until I see good pink in the washer. Then drain it and do the same for the cold line.
