Clear a Slow or Clogged Drain
Most slow drains are a plug of hair, soap scum, and grease in the first few inches of pipe. Clear it mechanically — stopper, plunger, drain stick, then the trap — instead of pouring chemicals down it.
What is actually broken
Most slow drains are a plug of hair, soap scum, and grease built up in the first few inches of pipe or inside the P-trap — not a deep blockage. It clears mechanically (pull the gunk out) far better than chemically, and the tools cost less than one bottle of drain opener.
Safety first
- If you've already poured chemical drain opener in, do NOT plunge or open the trap without gloves and eye protection — and tell any plumber you call. Mixing methods with chemicals in the line causes splash injuries.
- Never use a drain snake on a toilet — toilets need an auger with a protective sleeve, or you crack the porcelain.
The fix, step by step
1 Start with the stopper and the visible gunk
Remove the sink stopper or tub drain cover. In a bathroom sink, the stopper lifts out or unscrews from its pivot rod underneath. Most clogs are hanging right there — pull the (genuinely disgusting) hair plug off the stopper and the drain mouth with a paper towel or plastic drain stick.
Tip: This unglamorous step fixes most bathroom drains outright. Wear gloves and no judgment.
2 Plunge it properly
For sinks: block the overflow opening with a wet cloth, add enough water to cover the plunger cup, and pump straight down in short strokes for 20 seconds. For double kitchen sinks, plug the other basin. Plunging moves water both ways — it loosens plugs that pulling can't reach.
Tip: A cup plunger for sinks, a flange plunger for toilets. The little red cup plunger does almost nothing in a toilet bowl.
3 Use a plastic drain stick or hand auger
Feed a barbed plastic drain stick (or a 15–25 ft hand auger for tougher clogs) into the drain, twist as you go, and pull the clog out in stages, wiping it off each pass. Work patiently — forcing a snake can push a soft clog deeper and compact it.
Tip: Retrieve, don't dissolve. What comes out on the stick is proof the pipe is actually clear.
4 Check the P-trap if it's still slow
Bucket underneath, unscrew the two slip-joint nuts, and drop the trap. Tip its contents into the bucket and scrub the trap out. Reassemble hand-tight with the beveled washers facing into their joints.
Tip: Kitchen traps often hide a grease plug that looks like candle wax — hot water and a bottle brush clear it.
5 Flush and verify
Run hot water full-blast for two minutes. The drain should take it as fast as the tap delivers, with a clean swirl and no rising water or gurgling. Fill the sink and pull the plug as a final test — it should empty in one continuous rush.
Tip: For maintenance, a kettle of near-boiling water down kitchen drains monthly melts grease before it builds up. Skip this on PVC if your water heater is set very hot — warm tap water instead.
Stop and call a pro if…
Call a plumber if multiple drains are slow at once, you hear gurgling from other fixtures, or water backs up in the lowest drain in the house — that's a main-line blockage, a different and bigger problem.
