 And it's about water softening. And I always had it in the back of my head that you couldn't put a water softener on a system with a septic. And it wasn't because of the bacteria. I know that there have been conversations about that. And if you get like a really good water softener, that's not necessarily a problem. So like they're changing their mind on it. But it was always about putting salt down on your concrete sidewalks.
