During backwash, the water that drains out is horrifying. It’s brown, slimy, and looks like swamp juice.
But here’s the kicker: that swamp juice is proof the filter works. If you see clear backwash water, your filter might be broken.
So embrace the grossness. It’s a badge of honor. Your dirty backwash water is a tiny victory dance for clean drinking water.
One guy on a forum said his backwash water smelled like a wet dog. He was proud.
