Why are there bubbles when flush toilets drain

Hello! Glad to answer for you:1

Blocked pipes It may be that the pipes are blocked, or the drainage of the septic tank is not smooth, so that the water level in the pool rises, and the air in the downspout cannot be discharged into the pool when the upstairs is drained, and as a result, it is discharged in the toilet. One is that the main exhaust pipe outlet of the unit is blocked. per order.

2.Weather reasons If the septic tank is not blocked, then if the main exhaust outlet on the roof is not blocked, then it is necessary to consider whether it is not. 3.

Piping design flaws Problems with the piping design of the building, improper ventilation risers, caused these problems. Solve: Design the problem.

4.Water pressure problems due to excessive water volume, causing backwater. Resolved:

If the pressure is a problem, adjust the amount of water and the water pressure. Recommended reading: Shen.

Well, I remember that the lower part of the toilet design is a lying S-shaped sink, that is, in the middle of the section leading to the urinal, there is a section of empty water that will be left between the urinal and the drain, that is, there is air, and when draining, part of the air will not go down but go up, and there will be bubbles, which I remember is designed to prevent odor, which is why you will see water in the urinal that does not flow down.

Hello, I can totally understand what you mean, because I have the same problem with my toilet.

There is air inside the toilet, located in the waterproof port and the water seal directly, when flushing, the air is flushed out of the jet port, which not only causes the jet to be weak, but also splashes the sewage outside the toilet, which feels like the design and quality of the toilet.

My temporary solution is to prepare 100ml of water (about two bowls) before spraying the bubbles"Rush"into the toilet bowl and successfully complete the siphon.

Find after-sales solutions, no matter how he shirks, as long as there are bubbles, it is a quality problem.
