How to deodorize the toilet bowl and whether there is any device

Figure out the source of the smell in the bathroom, mainly floor drain, toilet, sink drain, ventilation fan (whether there is a window or not) 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 mix), you can use glass glue to hit a circle under the bottom, just block 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. 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.

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. Exhaust fan and air duct: Generally, when the developer delivers the house, a check valve will be installed at the mouth of the air duct, that is, a one-way valve, and the air can only flow from the bathroom to the pipe, not backflow.
