trap primer problem

[jennifersmith]

I have faced one problem with trap primer. The water seal in traps is necessary to prevent sewer gases from entering buildings, but because of this water is exposed to the air, leading to the release of sewer gas into the atmosphere. So please tell me how to solve this problem.

You could just add water. Some people add a little bit of cooking oil to help prevent evaporation.
Something like trap guard is another alternative:

Here is an example of an automatic trap primer:
