Water-saving toilet hack
Toilets use fresh water, and lots of it. Sure, you can buy a low-flow model, but you're still flushing with a (smaller) quantity of fresh, otherwise drinkable water.
Gregorylavoie decided to get double use out of that water by hacking his toilet. It's a neat, reversible modification: after you flush, you use the clean, incoming tank refill water for handwashing. Your slightly soapy hand-wash runoff fills the tank, and is saved for the next flush.
It's a simple, ingenious way to save water with little to no effort.
What do you think? Would you try this mod on your toilet?

however water has been referenced in literature/art/ history as an elements (eg earth/wind/fire/water).
washing you hands while standing over a toilet can't be too clean. the soap will have an abnormal amount of bacteria on the toilet. Better to probably have a liquid soap or attempt to have the hand washing a little bit away from the toilet (although that logistically speaking is much more work, time and money).

Manually dumping a basin or bucket comes to mine as about the most annoying thing one can do in this respect.
Really though, my biggest concern it that rubber "plunger" which takes so little warping to start to leak that it goes "on it's own", much less with assistance.
I haven't actually done any research into it, but I have seen rubberized products, um, hardened by detergents, or at least it appeared to be that way.
That is, it seems to shorten it's use. But I didn't "time it" to be absolutely sure.
I do know that excess water "dries out" leather products also (removes the oils from them), both natural and synthetics.
There are weather/detergent proof rubber gaskets out there; they use them in washing machines; but, I don't think that there is any expectation of detergents in the back of a toilet bowl, so they may not use them there. If they do, I am all wet, and I apologize for even mentioning it.....
I know that overuse of detergents (or having any residue left behind) IS a concern for mold, mildews and bacteria....
Still wouldn't be drinking from it.
In the countryside, where I grew up, we had a ritual at the 1/2 year mark, where we shut off the input valves, flushed as much out of the top as we could, and then unbolted it and took it outside for a good rinsing....sand, silt, and a lot of other stuff ended up in there....as I recall.
I guess it was better then trying to get to the trap every six months :-)
I guess one way or another, nothing is maintenance free :-)

For example, regularly 3-4 pounds of dog fur and associated gravel water.
*the voice of experience.....* LOL
wax? I know they dry out, i.e. dryrot the plunger seal (the one on the flap) and allow them to leak water into the bowl and have the tank constantly refilling itself.....and there are other "rubber" gasgets I have seen in some of the componants in some tanks....
Kidding....
No, what a great idea.....love the concept....

Oh, wait, I think I see. You're picturing a double failure: first, the float valve or flapper doesn't work properly, so the tank is continuously "filling." Second, the basin above doesn't drain fast enough and eventually overflows.
Yeah, you've got a point. In order for this to work you need to maintain your plumbing, rather than just living with "a toilet that gurgles all night" and the associated high water bill.

These kind of toilets are in a lot of people's homes. Bet you could find a few designs to overcome problems.
It still is a great idea though.
Ya'll know good and well that this idea will never go over in America! We Fat Cat Americans with our high-dollar homes and cars all that "Stuff" will never stand for washing our hands at the TERLIT, for cryin' out loud!!! We gots to have our nice clean wash basin with hot water and our pump anti-bacterial soaps and our pump skin softeners and all that Stuff, doncha know. HAHAHAAAA
On a personal level, I agree with digimancer: Brilliant idea! With a nice looking ceramic or fiberglass basin sitting on top of the tank, it looks to me like it would work out nicely for the average family. Then again, I've been wrong before. :-)
Not only that but that piece of OSB on the top of the tank looks great in the bathroom too.....
OK, I'll say what lots of you wanted to but didn't...
This is one of the dumbest "green" ideas I've ever seen...
So 2-5 mins of fresh drinkable running water down the drain while you wait multiplied by billions of people who have running water, multiple times a day is actually quite a huge waste.
Also germs and bacteria tend to breed in warm moist areas... So hopefully you dry your hands well.
Just my thoughts. =)
T-connector at the inlet, a hose running up the back or side of the tank, attached to a faucet fixture at the top would allow you to turn the water on and off, if the tank is already full the excess water would drain through the tanks internal overflow.
If you have any skill using fiberglass or cabinetry skills, you could mold the shape of the tanks lid and fabricate a counter top, or build a taller more elaborate table/cabinet above and around the tank in order to mount the fixture and an actual sink basin to. You could even add a sink trap to it for hair and whatnot, just remember to make sure you still have a way to get into the tank in case you need to fix it..
Not only would this conserver water but it could also conserve quite a bit of space in an otherwise small bathroom. Brilliant idea.
The only issue I have with this otherwise great idea is the problem of eventual soap scum buildup in the tank. Depending on your float ball system, you may have problems with leaks and valve stop-ups. Or maybe not. Awesome ingenuity!!
Then we would not need to buy an expensive compost toilet or have to use the "out house" in -50 below weather. Thanks for the modification idea!
