Pros: great water saving tool, fun to use
The Sink positive was one of the first products we had on Green Home and finally getting to install and use one was a treat. You don't quite realize how much water 1.6 LPF is until you watch it flow through a faucet...2 people are able to easily wash their hands on one flush...it's shocking.
If there is any complaint it's that it splashes a little bit of water around, but that's a small price to pay if you ask me.
The installation was very fast, and if we had figured out that we needed to cut the drain pipe sooner, it would have been over in 90 seconds. Great product.
