Buying Guide: Pressure Tanks For Irrigation Systems
Important purchase considerations include capacity, pre-charge pressure, material quality, connections, and compatibility with your pump and pressure switch. Here are the key factors to compare:
- Capacity and layout: Inline tanks fit tight spaces, while vertical tanks offer higher storage. Choose based on irrigation demand, water usage, and available space.
- Pre-charge pressure: Match the pre-charge to 2 PSI below your pressure switch cut-in setting. Regularly check and adjust to prevent short cycling.
- Materials and durability: Steel shells (with durable diaphragms) provide longevity; brass fittings resist corrosion and leaks in harsh environments.
- Valve and connection compatibility: Ensure 3/4″ or 1″ NPT fittings align with existing plumbing and that there’s room for unions or tees if needed.
- Maintenance and warranty: Look for tanks with long warranties and easy access for diaphragm checks or replacements. Some brands offer multi-year coverage, which can be valuable for irrigation systems exposed to outdoor conditions.
- System integration: Consider whether your setup requires an integrated tee kit or separate components. Ensure compatibility with existing pumps and switches to minimize installation complexity.
- Space and installation orientation: Horizontal tanks save vertical space; vertical tanks maximize capacity in a smaller footprint. Plan the mounting location with venting and accessibility in mind.
- Drinking water compliance: For irrigation-only uses, note that some larger tanks may not be certified for drinking water; verify the intended application and local regulations if needed.
In sum, the best choice depends on your irrigation scale, space, and maintenance preferences. Inline tanks offer compactness, while larger vertical tanks deliver higher buffering for large properties.
