Connecting Drain Pipe to Sinkにまつわる役立つ知識を詳しく紐解きます。

Start with the drain tailpiece. This is the pipe that sticks down from the sink strainer. If yours is too long, you might need to cut it with a hacksaw. Measure twice, cut once, and try not to cut your thumb. A good rule: dry-fit everything first. It’s like trying on pants before buying them—except these pants are metal and will hold your dirty dishwater.

Next, attach the P-trap. One end goes onto the tailpiece, and the other end points toward the wall pipe. This is where the jokes about “it’s just like that song ‘The Hokey Pokey’” come in—you put your left end in, you put your left end out. Just make sure the curve is facing down, not up. If your trap is upside down, you’ve invented a very sad fountain.

Now, slide the slip nuts and washers onto each end of the trap. The tapered side of the washer always faces the nut. If you put it on backwards, the pipe will leak, and you’ll be lying on your back under the sink, feeling like a defeated beetle. Trust me on this one.

The trickiest part: connecting to the wall

This is where most people start sweating. You have a horizontal pipe coming out of the wall, and you need to connect your P-trap to it. Often, the wall pipe is lower or higher than your trap. That’s okay—you can buy an extension tube or a hack saw to adjust the length. Don’t be scared to cut a little bit. You are the master of this pipe. You are the pipe whisperer.

Slide the wall-side slip nut onto your new extension, then push the extension into the trap’s other end. Then, slide the whole assembly toward the wall pipe. Push the extension into the wall pipe opening until it’s snug. Tighten both slip nuts by hand first, then give them a quarter turn with your wrench. Finger-tight plus a hair is the magic secret. Over-tightening is like squeezing a friend too hard in a hug—nobody likes it, and things crack.
