The toilet flushes efficiently. After flushing, the bowl has a normal amount of water in it. Often, a few hours later, the water in the bowl is much lower - sometimes half as low as it is right after a flush. In order to use the toilet, we flush in order to make the bowl fill with water again.
The bowl is cracked and is leaking down the drain. You will have to replace it. It may have cracked if the bowl hold-down bolts were overtightened, or the bowl was not able to sit flush (pardon the pun) on the floor. If the bowl rocks when it is first installed, instead of tightening the hold-down bolts, use a couple of tapered shims under the edge of it, then caulk to fill the gap and hide the shims.
Good luck.

You need to either bend the arm that connects tot he float down (if it is the type with the ball float) or adjust the height of the fill valve assembly. THis accomplished by slightly twisting the valve assembly carefully and sliding down a half of an inch or so and then twisting back to lock it in place.
This should fix you up right.
SOURCE: toto seems to flush,but suction not working and waste not emtying
check the discharge hole, meaning you have to take down the toilet.
and make sure the water in the tank is at a proper high. you need the volume to create the wirlpool and push the waste.

It sounds like the flapper is not seating after it has been raised with the chain. I have had this problem. Take the lid off the tank and see if the flapper, the rubber thing that covers the hole in the bottom of the tank, is hanging up on something. On mine, the chain was too long and fell down the hole and kept the rubber flapper from sealing the hole.
If the tank is filling up with water and the water keeps flowing in and going down the overflow, then the fill valve needs to be adjusted so that the water shuts off about one half inch below the top of the overflow tube. Best of Luck

flapper most likely needs to be replaced not sealing completely is one problem----- the other is float level not shutting off water valve --and other is bad water valve not shutting off or worn and needs to be replaced remove cover and turn water on watch water level lift float up if water turns off valve good----turn off water if drain down flapper bad and needs replacement costs a couple of dollars to replace -if water stays level in tank than float needs adjustment or replacement
Water Level Adjustment
1. To adjust, simply turn upper half of valve counter-clockwise to unlock, pull up till water line on valve is level with water line marked in tank, Fig.C then turn clockwise till valve snaps into locked position.
2. Turn on water supply to fill tank.
3. Tamper proof key is optional, and may be used to simply to prevent further adjustment once final setting is achieved. Fig D
