Here’s a concise, feature-style guide for unblocking an outside kitchen drain (e.g., a sink draining to an exterior grease trap, gully, or standpipe).

🔧 Feature: Unblocking an Outside Kitchen Drain 🚩 Symptom Check

Water backs up into kitchen sink Foul smell near external drain Slow drainage, gurgling sounds Visible standing water or debris outside

⚠️ Safety First

Wear rubber gloves & goggles Avoid mixing chemical drain cleaners (can create toxic fumes) If using a pressure washer or drain rod, protect nearby surfaces Ensure no electrical outlets or appliances are near standing water

🛠 Tools You May Need | Tool | Purpose | |------|---------| | Plunger (heavy-duty, flat-bottom) | Dislodge soft blockages | | Drain rod / flexible auger | Break up grease & solids | | Bucket & trowel | Remove sludge manually | | High-pressure nozzle / garden hose | Flush out debris | | Enzyme drain cleaner (grease-specific) | Dissolve organic waste | | Wet/dry vacuum | Suck out blockages |

📋 Step-by-Step Unblocking 1. Access & Inspect

Remove drain cover/grate (may need screwdriver) Use flashlight to check for visible blockage (grease, food scraps, leaves)

2. Manual Removal

Scoop out surface debris & thick grease into a bucket Dispose in trash (never down another drain)

3. Plunge

Seal overflow outlets (if sink connected directly) Plunge external drain with forceful up-down motion
