Es un producto muy bueno para evitar el paso de animales hacia el interior de la casa por medio del Drenaje.

i was impressed by its fit for 1.5 inch ABS pipe, it was perfectly tight. I am slightly sceptical of how it would fit on a bigger pipe as the adapteur is silicone only so quite soft. the small door has decent strenght but not enough to not open for water. one minor negative point: the small door does not have a rubber or silicon seal, it is plastic to plastic so a little bit of air could leak but very little

We have a floor grate in our basement that has been permeating a smell. After installation it seems that this has fixed the issue. Overall it was a cost effective solution and all we had to do was drop the peice into our drain. We have not needed to drain anything so I can only account for the device trapping the gasses.

we had a bad sewer smell comming out of the shower drain. this did the trick. after we put it in drain, the smell stopped and has not come back.
