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.
In Denver, tap water is moderate (80–150 ppm). Denver's water is moderately hard, sourced from snowmelt and groundwater. Scale buildup is noticeable but less severe than in hard-water metros. Water treatment varies by neighborhood.
Plumbers in Denver typically charge $110–170/hr. Most homeowners budget $800–2,500 for common repairs like fixture replacement, drain clearing, or valve repairs.
Colorado requires state licensing for plumbers. Denver requires permits. Homeowner exemptions limited to minor repairs.
Mix of pre-1950s and post-1970s construction. Older homes may have galvanized piping. Freeze-thaw cycles cause burst risk; insulation and heat tape are common. High altitude means lower boiling/freezing points affect equipment. Copper and PEX are standard in newer homes.
Denver winters regularly bring freezing temperatures. Pipe freeze risk is real, especially in older homes with uninsulated exterior walls. Heat tape and foam insulation on exposed pipes are worthwhile investments. Know where your main water shutoff is before winter.
DIY in Denver: Denver's moderate licensing and outdoor-focused culture support DIY repairs. Freeze-thaw maintenance and seasonal winterization are common homeowner tasks. High altitude knowledge is helpful. Most people hire professionals for electrical and HVAC work.
