Installing a bathroom sink. I have a tailpiece/downspout that I'm attempting to connect to a p-trap, and then subsequently connect the p-trap to the drain sticking out of the wall:
The p-trap I have is here:
Part C screws onto the thread of the drain (sticking out of the wall) perfectly fine. But part A is exactly the same size as the inside dimension of the same drain, and so it just butts up against the the drain with no way to secure the p-trap to the drain.
Furthermore, the tapiece fits into part E just fine, and I can screw E onto the threads, but I am still able to easily pull part E of the tailpiece., so I'm not sure how I'm supposed to affix it to the tailpiece securely. Any ideas?
