I just bought a hydro 7 because it looked like the best pump to go with for a beginner. I can’t figure out how to lock it though. Everywhere I read says to move the little black end piece to the side to lock. The black thing does not move to the left or right at all. It’s just stuck in the middle. I can just barely pull the little black piece out but it just falls back in if I do. Is it broken? I’m not even sure how to return this since I live in the us. If anyone could help me out I’d really appreciate it. I was really looking forward to giving pumping a test run. Thanks
