Buying Guide
- Compatibility matters: match part numbers (e.g., 0323, 0523, K478) with your pump’s model to avoid mismatches.
- Repair vs. replacement: use rebuild kits for refurbishment of existing pumps; use replacement vanes when the unit is out of service or irreparable.
- Oil-less models: note that some kits target “Q” oil-less configurations; confirm your pump’s internal filtration and oil configuration before purchasing.
- Model scope: some kits cover multiple models (AT03, AT05, RV03, RV05). If your system spans several models, consider kits with broader compatibility.
- Installation considerations: ensure you have the correct tools and follow safety guidelines when handling pressurized air pumps in septic systems.
