Unclogging a Bathroom Sink Drain - How To

Recently I noticed my bathroom sink was not draining well, as water started to back up into the sink while it was running. I decided to research solutions on how to fix it without having to call a plumber. There are many suggestions out there on ways to fix it. Using this information, I was able to clear the drain, so I thought I would share the experience here to help others who may have the same issue.

First I took an unfolded wire hanger and fished it down the drain to see if I could knock anything loose. It did get a lot of gunk on it so I could tell there was probably some build up around that area of the pipes.

Next, I looked underneath and found the drain pipe. It has a curved section known as a “p-trap” and this part can unscrew to take it off. I decided to try this to see if there clog was in this section.

First I put a bucket underneath and then started unscrewing the p-trap. It was a little hard to do, but I managed to unscrew it. As it came off, some water came out as expected, as well as a lot of gunk. Sure enough this is where there was a clog. Years of toothpaste and soap residue can really build up over time inside the pipes. It does smell pretty bad so be prepared for that.

I started cleaning out the pipe with the wire hanger and some paper towels. I cleaned the section attached to the sink as well as the pipe attached to the wall. I also cleaned out the p-trap pipe. Overall it was not too hard, just messy, so you will probably want to have rubber gloves and plenty of paper towels or rags.

I also ran the water a bit to clear out any loose material while the pipe was off so it would just go into the bucket instead of into the drain again.

Once clear, I put it back together and tested it out. The drain worked perfectly and the clog was clear! I think this is a project most people can do so if your bathroom sink is clogged, I recommend trying this method to clear it before calling for a plumber.
