    Hope you don't kill yourself because now you might not be filling the S-trap quite as well and can let sewer gas in.  If you want to save money either Buy a High Efficient Toilet or reduce the amount of water per flush.  It's rather simple take a 1 gallon bucket or  a little smaller then cut the bottom off.  Stick this to the bottom of your tank around the fill tube and drain, thus when it flushes it won't flush the whole tank just the little bit above and in the bucket.  You'll still get an effective flush because it's not the volume of water used it's the pressure generated by the height of it.  Plus if your whole tank flushes with each flush then something is wrong because most toilets use less than 1.2 gallons per flush.

    All the toilets i've seen leave enough water in the bowl to seal the sewer gasses in. You should test your toilet before doing this hack (read my comment above or somewhere around here).

    That brings up something I never understood: where does the water which enters the overflow tube from the top fill tube go? Does it go into the bowl directly, or does it go down the toilet drain directly?

    Thanks in advance for clearing up a big mystery in life!

    Into the bowl and down the drain, until the tank is filled up.

    Generally toilets are designed to fill the tank and bowl at the same time and when the tank is full, the bowl has just reached it's full point too as to not let water be wasted down the drain. This may sound stupid but toilets are actually pretty neat how they work if you sit and flush (I mean sit backwards with the tank lid off) and watch and study what the water is doing. Just a crazy point I wanted to add!!

    An even easier way is to fill a 2 litre pop bottle and place it in the toilet tank therefore when it fills, you will save 2 litres each flush and still have the water height for a good flush action! good luck.

    I agree with this technique. All the toilets I've seen work fine without a refill tube; they always leave enough water in the bowl to seal out gasses.

    Though you should test to make sure it works with your toilet; when you disconnect the refill tube, flush the toilet and see if there is enough water to seal the gasses out; if there is, then you're fine, but if there isn't, then you need the refill tube (though you may be able to reduce the flow).

    Instead of having the refill tube dangle, you should plug the end, because a dangling tube may be messy if it sprays a strong jet. What I did was I got a piece of the rubber tube, and I folded it, and then I used a cable tie to squeeze the fold together to seal it, then I cut the piece off and plugged it on the valve. Now all the water goes out of the fill valve's output and the toilet fills faster!

    P.S. in our A.I.O toilet, the refill tube was outputting a really powerful spray with a lot of water coming out. All that water was going down the drain! I removed the tube and tested the toilet and the bowl water line is nearly the same as if the tube was there! There was a noticeable difference in the time it took to fill the tank when I removed the tube. I've heard that 20% of the water goes out the refill tube!

    Also if you let the fill tube dangle you will most likely cause a siphoning effect and the tank will keep filling the end of the fill tube cannot be lower than the waterfill line.

    The tube will siphon water from the tank into the tank itself? no... :P

    I agree with the first comment, you need that water for the bowl and drain. Try harnessing "Grey Water" to save on water. I'm currently working on a design to collect grey water from my washing machine and the second story shower for flushing the first story bathroom.

    I have found that it is just not worth it to use grey water. Too smelly as it ages, filtering becomes expensive. I decided to save rainwater and use it for my basement washroom toilet. All gravity fed, no pumps, I made a sand filter and the water is very clean. I was recently given 2 solar panels and want to use them and a low flow pump to pump the rainwater to a height so I can also connect to the first floor toilet also. My only expense will be the 12v pump at this point. Have you been successful at using the grey water??

    I agree with:
