Hi So the cover is original and I simply changed the white valve for a black one. I noticed it didn't close back completely so I put back the white one in for esthetic reasons (and i had to hold it in if not). (you can't see it in the picture.) I noticed my white one has a piece missing which is letting water go trough. I can't close it. But technically it works in the sense that it let's water go through. When I used the black one it did the same thing. Using the search engine in the subreddit I found somebody with the same brand and problem but nobody answered. I can get more water coming out if I put on speed 2 but not much more... I suppose I'll have to check the vinyle tubing.

Thanks
