Customer Reviews

The best diverter on the market.  Nothing else comes close.  I have never had one complaint from my customers nor any maintenance or call backs.  Unlike others I have sold, the Amanzi is easy to install, does not leak or break and does not plug.

Finally, a diverter that's built tough! You can feel the quality – it's not flimsy like others. I love that it's made in the USA and the smart internal overflow means no extra hoses or potential mess when the barrel is full. Set it up once and forget it. Solid product.

I wanted a simple way to collect rainwater for my garden here in Oregon, and the Amanzi diverter was perfect! Installation was incredibly easy – took me less than 30 minutes. It's captured tons of water already. My plants are thriving, and I feel good about conserving water. Highly recommend!
