What's actually causing this
Drain clogs form when debris accumulates in the P-trap or the drain pipe below it. In bathrooms, hair and soap are the main culprits. In kitchens, grease and food particles solidify over time and narrow the pipe.

Step-by-step fix
-
1
Try the barbed drain tool first
Insert a plastic hair clog remover into the drain and twist it to grab the clog. Pull it out slowly — most bathroom clogs come out in one motion.
-
2
Plunge the drain
Cover the drain with a cup plunger, ensuring a seal. Plunge vigorously 10–15 times. Run hot water to check flow.
-
3
Baking soda and vinegar flush
Pour half a cup of baking soda down the drain, followed by half a cup of white vinegar. Wait 15 minutes, then flush with boiling water.
-
4
Remove and clean the P-trap
Place a bucket under the curved pipe beneath the sink. Unscrew the slip joints by hand (or with pliers) and pull out the P-trap. Clean it out and reinstall.

5
Run water and test
Run hot water for 2 minutes to ensure full flow is restored. Watch for any slow drainage, which may indicate a deeper blockage.

Nashville gets occasional freezes, but extended deep cold is uncommon. Pipes in exterior walls or unheated crawl spaces are the primary risk. A few nights below freezing per year means basic insulation is prudent.
