Plain and simple, I think the Sink Positive may be one of the best green inventions I've ever used. After you flush any toilet its water tank refills for the next flush. All the Sink Positive does is route that refill water first through a spigot (so you can wash your hands with it -- it's clean, just like it comes from the sink!) and then it sends the now "gray water" back into the toilet tank. I just can't believe how intuitive, simple, and water-saving it is.
Actually, most impressive/scary is how much water actually goes into each toilet flush (even a low-flow!). Whenever I've used this, I always have at least twice as much possible wash time as I need. Totally amazing and every toilet should have one. :) I'd give it 10 stars if I could!
reviewed August 30, 2008 at 5:42 pm 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.
My only negative comment is that it is made of rather flimsy plastic (it does adjust to fit your toilet tank) and expensive for what a basic product it seems to be. I still recommend it to everyone and think it is a great idea.
reviewed August 26, 2008 at 4:15 pm Great concept. If money were no object, I'd use these things everywhere -- it's a great way to reduce water consumption. Leaning over the toilet to wash feels a little awkward, but I'm sure you'd get used to it. And hey, if you can cut down your water usage by a couple of gallons a day, a little inconvenience is well worth it, right?
The $130 price is a bit steep though, especially considering it's just a molded piece of plastic, a simple faucet, and a couple of hoses.
reviewed August 22, 2008 at 1:25 pm Yeah, you think I'm joking but I'm not. The Sink Positive is so cool. Deej and I just installed one. It probably would have taken even less time had we actually read the instructions. But it's not very complicated. All you do is turn off the water, take off your existing lid, unplug the tube that goes from the water source to the toilet overflow pipe, twist in the faucet bit to the Sink Positive lid, pop on some tubing, connect a tube here and there, batta bing batta boom, you've got yourself a greywater system!
Helpful hint on installation: They mention this on the instruction sheet (which we read part way through after we realized the sink was about to overflow the first time we tried to use it), but each toilet is a little different in terms of size. You need to make sure that the tubing that goes from the drain hole on the sink into the toilet overflow pipe isn't bent or hitting the bottom of the pipe. If it is, the water in the sink won't drain into the tank quickly enough to shut off the water and you'll end up with something of a waterfall going down the front of your toilet. We cut about 1 and 1/4" off the bottom of our tube and that solved everything.
The flow from the faucet is really quite strong and nice and provides PLENTY (more than plenty) of water for you to wash your hands. In fact, with one tester flush, Deej and I were both able to wash our hands. It was crazy.
Another quick note on the design, I'm a fan of the fact that there's a little dish area for a bar of soap built into the left hand side of the lid. You can also set a thing of liquid soap on the sink extender to the right hand side (depending on the size of your toilet tank). You can see how we've got ours set up in this action shot.
You do have to bend over the toilet a little, or maybe straddle it if you prefer that. So that's a tad awkward, but once you get used to it, it's cool. There is also a little bit of splashing if you're an "active hand washer" because (at least on our toilet), the water comes out with a good amount of force and it's a small sink. So if other folks are in line after you, you may just have to let them know you didn't miss the toilet bowl...it's just water. Or else just take a little more time and be a little more gentle on the ol' paws. Then you really just have to watch out with dripping when you move your hands away from the sink to where ever you've got your hand towels.
All in all, it's awesome. I'm thoroughly pleased. It's a tad pricey (the $129.95 is plus S&H)...but hey, good karma and water conservation are worth it.
