How do you unblock a sink past the U bend?

To unblock a sink past the U-bend, first try baking soda and vinegar or plunging; if that fails, you'll need to remove the U-bend (P-trap) to clean it, using a bucket underneath to catch water and gunk, and then use a plumber's snake (or auger) fed into the pipe that goes into the wall to break up stubborn clogs further down the line, repeating cleaning if needed.

How to get a drain snake past a bend?

To get a drain snake past a bend, feed it in short increments while rotating the handle slowly, gently wiggling or using a "bobbing" motion (forward/backward) to help the tip find the curve; for stubborn bends, try going in reverse or using a drill attachment on low speed to navigate the turn without forcing it, and consider removing the P-trap for easier access.
 

Why shouldn't you use baking soda and vinegar to unclog a drain?

You should avoid using baking soda and vinegar to unclog drains because the fizzing reaction creates weak, temporary pressure that doesn't break up tough clogs, can push debris further down, and the resulting salt water isn't a strong cleaner; plus, vinegar's acidity and the reaction's buildup can damage pipes and rubber seals over time, making the problem worse or leading to leaks, with better options being plunging, drain snakes, or enzyme cleaners.

Why isn't water going down my sink?

Water isn't going down your sink usually because of a clog from hair, grease, soap scum, or food, often in the P-trap pipe under the sink or further up the drain line, but sometimes it's a venting issue where air can't get in, causing gurgling and slow draining. To fix it, first try boiling water or a baking soda/vinegar mix, then check the P-trap for blockages, or use a drain snake for deeper clogs; if it's still slow, a vent problem might be the culprit.
