I also used to always choose everything only the best. I think that when it comes to pipes and drains, you should trust professionals. The guys helped me https://www.pomwaterproofing.ca/french-drain/ - I bought a house for myself, but of course I couldnt solve all the dampness issues myself. Impressed with how quickly they arrived. I dont understand anything about what they do, but I can say that for the second year I dont know any problems. And there is no unpleasant smell from the sewer.
