The bathroom often smells what is going on and is not a problem with the toilet

It could be a sewer problem, a floor drain. Some floor drains have no anti-odor effect! Toilet problems are generally impossible·· Otherwise, you can see if the two small holes under the toilet base are sealed!

If there is a smell in the bathroom, it should be solved from the source. Find out the source of the smell in the bathroom, mainly floor drains, toilets, sink drains, and ventilation fans (whether there are windows or not).

1.The first check the toilet, the current toilet is generally sealed with glass glue, you can get close to smell it, if there is a smell (the kind of sour smell discharged from the sewer, very special, and not easy to confuse), you can use glass glue to make a circle under the line, seal it, and then look at the water seal of the toilet, if there is still a smell, it means that the water seal of the toilet is destroyed, and then you have to change the toilet.

2.Floor drain: Be sure to install an anti-odor floor drain, ask closely, if there is a continuous odor, then the floor drain is not odor-proof, just replace it with a new one, buy a core online is easy to replace, if there is no smell can be eliminated, there is no floor drain at home to plug it with sandbags.

3.Sink: Under normal circumstances, the water pipe installed by the developer has a water seal (that is, an upward bend, which can retain a part of the water to isolate the smell of the sewer), but it is not necessarily, so you should pay attention to it at this time.

Generally, when the master installs the sink, he defaults to the water seal in the sewer pipe of your house, so that he will directly extend the sewer into the pipe. If there is a persistent sour smell in the bathroom at this time, it is likely that there is no water seal, if you smell a continuous smell in the sink, it is easy to solve, bend the pipe that stretches into the sewer pipe below, and then seal the bottom, and the problem is solved immediately.

4.Exhaust fan and air duct: Generally, when the developer delivers the house, the check valve will be installed at the air duct mouth, that is, the check valve, the gas can only flow from the bathroom to the pipe, can not be returned, if there is no installation, the home must be installed when installing the exhaust fan, it is only dozens of dollars a, and the exhaust fan should also be installed well, and the ventilation should be done frequently.

Precautions. If you have a window, you should often open the window for ventilation, and at the same time turn on the ventilation fan, and you can also put some air freshener to ensure that the bathroom does not have any odor.

Odor in the bathroom is a headache, where does the smell come from?

Generally, the first thing that comes to mind is floor drain, basin sewer seal, toilet seal, and so on.

When these locations are confirmed to be fine, but there is still a strong smell in the bathroom, what is the root cause of the problem?

I have encountered such a situation, the newly renovated house, the floor drain is sealed with water, the water under the wash basin is made of a backwater bend, and the toilet is also strictly sealed, but the bathroom still often has an obvious smell.

After a period of observation, I found that the problem was coming from the bathroom exhaust vent.

Nowadays, in order to improve the sealing and sound insulation effect of the house, most of the people use broken bridge aluminum doors and windows, and the sealing performance is very good. At this time, if the kitchen turns on the range hood, a large amount of air is discharged outdoor, the doors and windows are sealed very tightly, and the outdoor air has no channel to supplement the room, at this time, the bathroom exhaust outlet forms an airflow backflow, although the exhaust outlet is also installed with a check valve, the sealing is very poor, the airflow backflow is obvious, the smoke of the cigarette can see the air backflow at the exhaust outlet, and even the backflow can be felt by hand.

Solution: If there are windows in the kitchen, be sure to open a little window when turning on the range hood so that the outdoor air can form convection.

If the kitchen doesn't have windows, open a few windows in the living room or bedroom adjacent to the kitchen to allow air to come in.

The bathroom exhaust outlet is a high-quality check valve, preferably with a rubber sealing ring.

The toilet at home always emits a pungent odor, and I feel nauseous when I enter the bathroom.
