Sump Pump Inspection Checklist: Field Steps, Common Defects, and Report Language (with Voice Notes)
A sump pump is one of the most important “invisible” systems in a home.
When it fails, the result is often immediate: water in the basement/crawlspace, damaged finishes, mold-like growth, and expensive cleanup.
This checklist is written for inspectors: what to look at, what to photograph, what you can test safely, and how to describe limitations.
Important
Do not flood a sump pit or defeat safety devices to force operation. Follow your SOP. Many inspections are visual + basic functional checks only.
Step 0: Identify the Setup
- Sump pit location
- Pump type: submersible / pedestal
- Discharge piping material and routing
- Backup present: battery backup / water-powered / none observed
- Alarm present: audible alarm / none observed
Photo set:
- Pit overview
- Discharge piping at pit
- Discharge termination exterior
Sump Pit Checklist
- Pit cover present and secure (reduces humidity and hazards)
- Water level observed (if present)
- Debris/silt buildup (can clog pump)
- Float switch moves freely (visual)
Pump & Power Checklist
- Power source: dedicated outlet? GFCI? (document what’s present)
- Cord condition (no splices)
- Pump appears securely mounted
If you see corrosion, loose wiring, or unsafe conditions, note it.
Discharge Piping Checklist (High-Value)
- Check valve present (prevents backflow)
- Discharge pipe supported
- Pipe routed to exterior (not into sewer unless permitted)
- Termination point discharges away from foundation
- No obvious freezing risk (missing insulation in cold zones)
Common defect: discharge terminating right at foundation wall.
Functional Check (If SOP Allows)
Options (choose what’s appropriate):
- Observe operation if pump cycles naturally
- Lift float slightly (if accessible/safe) to confirm pump starts
Document exactly what you did:
- “Observed operating during inspection” or “Float tested” or “Not tested due to ____.”
Backup & Alarm Checklist
- Backup pump present (battery/water powered)
- Battery age/condition not typically verifiable visually — recommend service/test if present
- Alarm present and appears operational (if test button present)
Report Language Templates
Pump not tested
“Sump pump was not tested due to ____ (no water in pit/covered pit/inaccessible/unsafe). Recommend qualified contractor verify operation and discharge routing.”
Discharge too close to foundation
“Sump discharge terminates near the foundation. Recommend extending discharge to direct water away from the structure to reduce moisture intrusion risk.”
Missing check valve
“Check valve not observed on sump discharge piping. This may allow backflow and short-cycling. Recommend plumber evaluation/correction.”
Backup recommended
“No backup sump pump system observed. Consider adding a battery backup or alarm for improved protection during power outages.”
Voice Note Structure (Fast)
Dictate in this order:
- Location → what’s installed → what was tested/observed → key defect → recommendation
Example: “Basement sump pit: submersible pump present. Discharge observed terminating at foundation; recommend extension away from structure. Pump not tested due to covered pit.”
Where ReportWalk Helps
Sump pump findings are short but high-stakes. ReportWalk helps you dictate a clean, defensible note quickly and attach the 2–3 photos that support it.
Quick Field Checklist (Copy/Paste)
- Identify pump type + pit cover
- Check debris/silt + float freedom
- Document power/outlet/GFCI (visual)
- Discharge routing + termination away from foundation
- Check valve present
- Backup/alarm noted
- Functional check documented or limitation stated
