One, why does a squat toilet have a small hole?
1、When unclogging a toilet, the spring mechanism may not retract. The plumber will then open a hole. The diameter of this small hole is just large enough to accommodate the unclogging cable. With this small hole, the cable does not need to be inserted from the back, and the unclogging work can be performed within the curved passage. However, this hole will later affect the sealing of the S-bend, making the toilet emit a strong odor. Therefore, the location and size of this small hole depend heavily on the choices made by the installer during installation.

2. The manufacturer provides two drainage outlets, one at the front and one at the rear, commonly found in restaurants and other public restrooms. This is due to high traffic volume, where toilets often become blocked and cannot be promptly repaired, and delaying use is undesirable. Therefore, workers are forced to use forceful methods, such as using sticks, to clear the blocked toilets.
Two. After drilling, cleaning, and plugging the toilet hole, how to seal the hole?
If the holes are small and the fragments are few, apply AB glue directly to the joint. If the holes are large and there are many fragments, first use 502 glue to fix the fragments in place. After patching the fragments one by one, fill the gaps with a large area of AB glue. Of course, this connection is not aesthetically pleasing. To achieve a better appearance, you need to use a specialized ceramic adhesive. The plastic putty used for repairing pipes, although waterproof and highly effective, is not aesthetically pleasing. After application, use a hairdryer to speed up the drying process, and be sure to follow the instructions for using AB glue.
Three. How to unclog a toilet.
1. If the blockage is not severe and there is water leakage, simply flush with a large amount of water to create sufficient water pressure. Alternating washes can resolve the issue.
2. Place the mop head against the drain opening, then turn on the water supply to submerge the mop. Then, firmly press the mop downwards, ensuring it reaches the drain opening, and quickly lift the mop. This allows for repeated extraction of the blockage, enabling the toilet to function smoothly.
