I thought he was asking about the drain traps. I guess I don't know what a 'drain line' is.

Sounds to me he's asking about drains specifically! I don't think he said anything about holding tanks.

And then it magically evaporates and never enters the holding tanks and then the sewer system or ground water. The reason I made my comment was that Bill stated it didn't damage his pump. That is in the fresh water system, and not the grey drains, tanks or pipes.
