- Flow and Pressure: Look for kits rated up to at least 250–300 PSI to handle typical winterization flows without leaks.
- Length and Reach: A longer hose (around 12–17 inches) can help reach tight spaces under sinks or in RV compartments.
- Valve Design: A built-in shut-off valve helps prevent backflow and makes operation safer during blowouts.
- Safety: Use eye protection and follow manufacturer instructions when working with compressed air.
- Special Features: Some kits include dual adapters, extra washers, or Teflon tape for leaks prevention; consider these if you value setup ease.
