Why does the toilet tank have two buttons

For the sake of water saving, a small flush of water is used for the post-flush of the urine, and a large flush of water is used for the post-flush of the stool.

You open it and look at it, there are two buttons at the bottom, corresponding to two buttons, I've seen it, one has more water, one has less water, but there is only one, I think it's because of the beauty of the two, or the business to deceive people to get two, I don't know.

Under normal circumstances, the two buttons on the toilet tank will be one large and one small, the big one is the big flush water, and the small one is the small flush water, which is the design of water saving, and the current toilet is basically like this, the situation you said may be to press any one is to flush half of the water, and press two at the same time to flush the whole water, otherwise there will be no situation you said.

There is a difference between the buttons, but there is no difference in using them, because there is a backup to prevent one from breaking and not flushing.

One is a big flush and the other is a small flush, the water output is different, and it is set up for everyone to save water.

There is a difference, it is exactly one that you said is to flush half of the water, and the other is to flush a tank of water.
