beskrivelse:

Pictures showing two traps located underneath a drain cover. The centre image shows a few insects stuck to the underside of the cover. The cover functions as a trap by blocking the back flow of gasses using the trapped water and any positive pressure in the pipe will cause the cover to come out.
