There is too little water left after flushing the toilet, which is related to the structure of the toilet. Different products have different structures, and the remaining water will be different. If the water in the toilet in normal use suddenly decreases, it may be because the water pressure is too high and the water in the water tank is too full, so the siphon phenomenon will become more intense when the flush button is pressed, and the water left in it will naturally decrease after flushing.

You can try to adjust the water pressure lever in the water tank.

At present, most toilets on the market are water-saving toilets. After a period of use, you will find that the water pressure of the toilet becomes too high. At this time, the water coming out of the toilet will become too high, and there will be too little water left in the toilet after flushing. You can try to adjust the adjusting lever in the water tank downward, so that the water volume will drop. Don't tune too much at once. Try several times to find the right position, and then tighten the screws.

Adjust the inlet valve.

The inlet valve becomes higher after being used for a period of time, resulting in excessive pressure and too fast water outlet. At this time, it is necessary to disassemble the water inlet valve, remove the buckle of the water inlet valve inside, and adjust the height by counterclockwise rotation, so that the problem of too little water left in the toilet can be adjusted.

Pull out the water supply pipe in the water tank.

Drinking bottled water in the water tank can reduce the volume of the water tank, reduce the water storage capacity of the water tank and save water. Pull out the water supply pipe to adjust the sealed water in the toilet. Generally, the water supply pipe is plugged into the drain valve on the right. Just pull it up and put it in the water tank, so this problem won't happen next time.

Various problems will inevitably occur when the toilet at home is used for a long time. Whether the water tank is ineffective or the pressure is too high, the toilet leaks or the toilet sump returns too slowly, only by finding out the reasons can we take corresponding measures to solve it. The problem that can be solved by itself is not big, and it will not affect the normal use of the toilet after repair. If you can't solve it yourself, you must find a professional to solve it.
