Why does the water level of my toilet urinal squatting drop for odor insulation?

This is not caused by the loss of water from the lattice caused by cracks in the bend where the water is stored, but by the air pressure in the pipes when someone is flushing the water upstairs. The bend where the water is stored is relatively shallow. The water level of the odor is directly connected to the sewer pipe, which is of course affected by the air pressure.

If you don't believe me, you can scoop up the water in the bend a little. The air inside the duct is connected to the outside of the toilet. There is no such phenomenon.

The principle of air pressure. There is also water poured into the horse poke, due to the fast flow rate, the water in the toilet quickly leaks into the sewer pipe, and there will be no stagnant water in the barrel body, and at this time you will not have debris ** back if you throw a bomb. If I poured the water into it slowly, there would be water in the poke, so I had to pour the water into the bucket slowly as if the toilet was flushing normally in order to prevent a little water from accumulating in the bucket (to prevent the smell from escaping).

I've tried several toilets and they've all been like this.

I think as long as your home does not leak water, in fact, the principle is relatively simple, the bubbles also have volume, when it discharges the water that you isolate, it squeezes out a certain amount of water, when the bubbles run out, the water is squeezed out, of course, the water level will drop...

Check whether the amount of water in the tank is normal, it is estimated that the amount of water is abnormal, and it is related to the float. As soon as the upstairs is watered, the floor drain in my room will emit a strange smell. I didn't go home for a few days, and when I came home and opened the door, I smelled a smell, and I searched for the smell, but it was a floor drain.

If you are using the toilet yourself, for example, if you are draining the toilet, the floor drain in another location will emit an odor.

For some high-rise residential low-rise residents, it is not enough to seal it. can only barely withstand the impact of some air waves. If several households upstairs ship at the same time, there will definitely be a stronger and less air wave.

Hit this water level. If you can't resist it, the odor will break through the water seal and overflow.

If it is a free-standing septic tank, it should be caused by poor return air from the sewer pipe. Check for repairs.

The main drainage bar is not well connected with the atmosphere.

Check the drainage bar.

Raise the squatting pit and install a back bend to change the squatting poop into a toilet.

Because it needs to be flushed with water, so it is not so cost-effective to use water to isolate the odor.

The earliest squatting toilet used a straight-through defecation type, straight up and straight down. Some of the following use septic tanks, and some are directly a pit, and the smell cannot be eliminated!

Due to the obvious disadvantages of the in-line type, it cannot isolate the odor, so it can only be used in train toilets and some places.

As a result, the squatting toilet was improved to use a curved backwater structure to isolate the odor returning downstream of the sewage pipe.

The detour backwater structure is an innovation, which basically solves the phenomenon of "odor return".

So, why use water to keep out odors? In fact, it is very simple, this structure is the most convenient and easy to implement, and at the same time, it does not need to add a complex filter, which is both cost-effective and easy to maintain.

Because the density of the water is quite large, it can effectively insulate odors.

1. On August 1, 2009, the GB2626-2006 "Self-priming Filtering Anti-particulate Respirator for Respiratory Protection Equipment" standard was implemented, which stipulated that the protection levels for particulate matter were: KN90, KN95 and KN100.

Second, the level of protection against oily particles.
