What Is Under The Bathroom Sink?

Plumbing parts under sink

I often forget that not everyone speaks plumbing. To make things more complicated some plumbing component names are not self-explanatory at all.

If you have to buy a part, look something up, or call a plumber it will be easier if you know the names of the plumbing components.

The bathroom sink, for example, has quite a few plumbing parts that can break, leak, or become blocked.

So, let's take a look at what is under the bathroom sink.

  1. Angle stop shut off valves
  2. Pop-up drain
  3. P-trap (made up of two parts)
    • U-bend
    • Trap arm
  4. 1 " Drain pipe

Great, I’m glad you found it helpful. It’s always easier to complete a project when you know what parts and materials are called.

Why would a newly installed bathroom sink smell like sulphur? Is it related to the Flex pipe used as Lowe’s has suggested??

One possibility is that the trap was not installed or it was installed incorrectly. The U-bend part of the trap is sometimes installed incorrectly or left out of a drain installation. This can allow sewer smells to come up through the sink drain (see <a href=”http://plumbing.about.com/od/drains/a/Drain-Trap-What-Is-The-Purpose-Of-A-Drain-Trap.htm”>The Purpose of a Drain Trap</a>). Maybe that is what you are smelling.

If the trap is installed correctly you may want to contact the sink manufacturer to see if anyone else has reported a similar smell.

What do you call the thingamajig under the sink that is used to control the movement of the drain stopper? I had someone remove my drain stopper to clean gook from the sink and now it appears to be a leak coming from that thingamajig. Please help. What would I need to do to fix this?
