Hello,
I just got my octo varios 4 and it comes with a step up for 3/4 hose but it doesn't lock in at all it just slips out. I dont know if I'm just stupid but I cant find a way to keep it snug. The top piece cant go on the pump without the larger bottom piece. If anyone knows what im doing wrong I'll appreciate it
