Hi, i'm connecting up a new sink in my garage. The sink does not align with the wastage pipe, so I want to use a flexible pipe joiner to connect the top of the sink with the p-trap. I thought this would be simple, and could just fit the pipe joiner directly on to either side, but it's just not connecting. Do I need some sort adapter or am I missing something fundamental?
The product i'm using:
