What Causes Slow Draining Bathtub
A slow-draining bathtub is most commonly caused by a buildup of hair, soap scum, and body oils in the drain trap and drainpipe. Over time, these substances combine with mineral deposits from hard water to form a stubborn clog that gradually restricts water flow.
Boise-specific factor: Boise's hard water (6.6-15 GPG) accelerates drain buildup by depositing calcium and lime inside pipes, which traps hair and soap residue more effectively. Homes with original cast iron drains in Boise's North End are especially prone due to rough pipe interiors.
Signs You Have Slow Draining Bathtub
Watch for these warning signs in your home:
- ✓ Water pools around your feet during a shower
- ✓ Bathtub takes several minutes to drain after a bath
- ✓ Gurgling sounds as water drains
- ✓ Unpleasant odor from the drain
- ✓ Water level rises when other fixtures drain nearby
Can You Fix This Yourself?
Remove the drain cover and pull out any visible hair with needle-nose pliers or a plastic drain snake (available at any hardware store). Try plunging with a flat-bottom plunger. Avoid chemical drain cleaners — they can damage older pipes common in Boise homes.
If the problem persists or you're unsure, call a licensed plumber. Attempting complex repairs without proper tools can cause further damage and void warranties.

Frequently Asked Questions
Why does my bathtub drain slowly even though I cleaned it?
The clog is likely deeper in the drainpipe, past the trap. Surface cleaning only removes what you can reach. A professional snake reaches 25-50 feet into the pipe to clear deep obstructions.
Should I use Drano on a slow bathtub drain?
We don't recommend chemical drain cleaners, especially in older Boise homes. They can corrode cast iron and galvanized pipes, potentially creating leaks. Mechanical clearing (snake or hydro jet) is safer and more effective.
