Technical Documents

Before You Buy

System Requirements

Water Pressure & Flow

  • Requires 15-30 PSI water pressure (30 PSI maximum - higher pressure will damage the system)
  • Flow rate requirements vary by length: 25 ft needs 182 GPH, 50 ft needs 365 GPH, 100 ft needs 730 GPH, 328 ft needs 2395 GPH
  • Check your water supply capacity before ordering longer lengths

Filtration Needs

  • Requires 80 mesh minimum filtration to prevent clogging
  • System includes fabric filter, but upstream filtration is recommended for dirty water sources
  • Regular filter maintenance is required for optimal performance

What's Included vs. What You'll Need

Included with Your SumiSoaker Max:

  • Irrigation tubing (25 ft, 50 ft, 100 ft, or 328 ft length)
  • Dual-threaded tube connector (1" and 2" connections)
  • Fabric filter
  • Adjustable end stopper
  • 1-inch threaded coupling
  • Installation instructions

You'll Need to Purchase Separately:

  • Pressure regulator (30 PSI maximum - required to protect system)
  • Garden hose connector or irrigation fittings to connect to your water supply
  • Additional fittings based on your specific setup

Ideal Applications

Perfect For:

  • Direct-seeded crops and seedling establishment
  • Market garden beds (covers up to 8 standard 30" beds)
  • Low-growing crops like salad greens, herbs, and vegetables
  • Greenhouse and tunnel production
  • Areas requiring gentle, uniform watering

Not Recommended For:

  • Crops taller than 7 inches without raising the tubing
  • Areas with consistently high winds
  • Systems without pressure regulation capability
  • Water sources with heavy sediment (without proper filtration)

Planning Your Coverage

Coverage Guidelines:

  • Maximum width: 33 feet (16.5 feet each side) at full pressure and flow rate
  • Coverage width decreases with lower pressure or lower flow rate
  • One line covers approximately eight standard market garden beds
  • For multiple beds, space lines 18-26 feet apart, depending on pressure

Crop Height Considerations:

At 3 feet from the tubing, the water spray height is 25 inches. Plants taller than this will block spray to areas beyond them. Consider using risers for taller crops or permanent installations.

 

Installation Considerations

Setup Requirements:

  • Hand-tighten fittings only (no tools or thread sealant needed)
  • Must install with text side facing up
  • Requires gradual pressurization starting at half pressure
  • Can be cut to custom lengths as needed

Maintenance Expectations:

  • Seasonal storage recommended (drain and roll up)
  • Filter cleaning required periodically
  • System designed for 10+ years with proper care
  • No mechanical parts to maintain

Questions to Ask Yourself

  1. Do I have adequate water pressure and flow? Check your system's PSI and flow rate capacity.
  2. What's my coverage area? Measure your beds to determine optimal tubing length and spacing.
  3. Do I need permanent or portable irrigation? This affects your connection and mounting decisions.
  4. What's my crop height? Determine if you need risers for taller plants.
  5. Is my water source clean? Consider additional filtration for well water or other sources with sediment.
