Before You Start

Turn off the water supply to the sink and place a bucket underneath the trap to catch water and debris. Have towels handy to wipe spills and protect surfaces from splashes. The pea trap is typically located directly beneath the sink; access may require removing a few mounting screws. Wear gloves and goggles if particles or wastewater could splash. Time estimate: 30–60 minutes depending on clog severity.

Step-By-Step: How To Clean A Pea Trap

  1. Place a bucket under the P-trap and detach the trap fittings by turning the slip nuts counterclockwise with a wrench or adjustable pliers.
  2. Carefully lower the pea trap and inspect for obvious clogs, noting the direction of any water flow when you tilt the trap.
  3. Clean the trap interior with a P-trap cleaning brush flexible bore brush to remove hair, grease, and debris. Scrub all surfaces, especially the bends.
  4. Check the drain hose and inlet pipe for buildup; insert a flexible drain auger kit for P-trap cleaning into the pipe to dislodge stubborn material.
  5. Run warm water through the trap after scrubbing to rinse loose particles into the bucket. If water backs up, re-try with the auger or snake to clear the pathway.
  6. Reassemble the trap with the seal rings properly seated. Hand-tighten, then give a final snug turn with pliers—avoid overtightening that could crack fittings.
  7. Turn the water back on and run the faucet to verify free drainage. Check for leaks at all joints and tighten as needed.

Troubleshooting
