I was looking for information about the Gerber Viper toilet since we are currently looking at plumbing fixtures for our new home. I found one plumber's website that has a video demonstration of the flushing power of the Viper.

I was surprised by how much this thing can handle. It's a 1.6 gallon per flush, gravity-fed toilet. There's no pressurized air to assist, and still, this thing handles everything they throw at it.

Aside from that, the video is kind of funny to watch all them flush all this stuff.
