Pump Start Relay vs. Pressure Tank for Well Irrigation

Installing a well for a 10-zone rotor system (6–10 GPM/zone). Asks if Hunter pump start relay alone suffices, or if pressure tank + switch needed. Also seeks pump brand recommendation.

Pump Start Relay Is Standard

Yes, a pump start relay (activated by controller's pump/MV circuit) is the standard, cost-effective method. No pressure tank required.

Critical Requirement: Perfect Suction Seal

• Suction line must be absolutely airtight.
• Pump must draw water immediately on startup or it loses prime.
• Self-priming pumps help but don't fix a leaky suction line.
• A pressure tank's advantage: stored water helps maintain prime.

Pump Brand Recommendations

• Berkeley, Sta-Rite, Myers, Flint & Walling—all Pentair brands with good parts availability.
• Choose based on local dealer support and parts stock. When a pump fails, fast parts access minimizes downtime.

Submersible Pump Follow-Up

Owner asked about submersible pump for aesthetics. Not recommended: sump-style lacks pressure; well-style requires vertical casing, horizontal install kills bearings; electricity in water poses safety risk. Use a conventional above-ground pump in a buried vault or pit if appearance is a concern.
