If the French system does not work, you can try alternative solutions. Starting with banal pipes and ending with the creation of small rivers. Of course, I don't really understand all this, but when my cousin faced a similar problem, he solved it absolutely simply. Spent some pipes. Idk. Maybe this will help. In general, I don't like what the French come up with. My French car, motorcycle, helicopter broke down. And I even fell off the scaffolding once. fortunately, he remained intact. since then, I have been taking only American scaffolding from this site:
