SinkPositive, Clean water for hands, gray water for the bowl

SinkPositive is the original patented retrofit application here in the US. HGTV featured it last year. Japan has used it for decades.

When properly installed, the supply and drain tubes from the sinkpositive sink do not come in contact with the water in the tank. The used water from the sink flows directly to the bowl through the overflow pipe. It is very important to keep the water in the tank clean and we support your concerns with our design.

Dirty water FTW

Yes, after washing your hands the water should be dirty. That's why the water drains to the bowl and becomes sewer water.

Great idea. It is funny how many people think you are using the waste water going out of the toilet when it is actually the drinking water that goes to the tank and is being used to wash your hands.

@fancycrow , Yes, it is funny how many people think they are using the "dirty water" after the flush, but it is even more humorous how many people just don't get that the water drains to the bowl not the tank. It's a simple concept.

And all the soap scum you have to wash out of your toilet every day? Hair trimmings?

[h2oknow]

You would simply have to clean the bowl everyday, and if you are concerned about soap sucm you are certainly concerned about other "scum" in your bowl, anyway. I suggest you use the bathroom sink as a place to trim your hair.

I actively save water by never washing my hands after i poop.

I save millions of dollars a year

No you're completely missing the point. When you do need to use the toilet you will wash your hands after. This toilet will use the exact same amount of water with or without this sink. Obviously you wouldn't use this sink if you didn't first need to flush the toilet. Just use some logic. This type of mechanism would be dirt cheap to mass produce.

It's a great idea with perfect execution...

После установки счетчиков мы так и делаем, только насадки нет, а просто перевернули крышку бачка, в которой уже есть отверстие...

if this technology was incorporated into public urinals every lazy fool would leave the bathroom with his hands clean.

Yes, the water is from the house water supply which is not heated. So, really the water temperature is no different than turning on the cold water valve/spigot at any other point in the house. Science has proven that it is only a myth hands must be washed in warm water. Soap and clean water are the necessary elements.

This is an amazing idea, but the water supply to toilets is always ice cold.

Before I would install this thing, I would want to completely drain and sanitize the inside of the tank, then when I install the SinkPositive, I would want to completely seal the plastic tubing, so that there is no leaks at all, or that the evironment inside the tank does not contaminate the water in the plastic tubing, especially if the toilet sits without use for several days. I would not want to install this thing in an old dirty tank, with old parts.

@pkillor they still do...just with no soap.

[lodevijk]

The simplicity of this solution is just AMAZING! This concept is pure genius.

This device many years ago that used in Japan...
