About Water Box Systems

The Water Box is a general-purpose intake screen system for ponds, canals, and sumps. It features a large screen area and float-valved level control to deliver consistent flow to pumps and pressure filters. Commonly installed upstream of BIG or TIG filters for coarse screening.

Why Choose Water Box?

Large Screen Area

High surface area maintains low intake velocity, preventing screen blinding and extending time between cleanings. Handles heavy debris loading effectively.

Float Valve Control

Self-regulating float valve assembly maintains consistent water level and flow. No external controls or power required—simple, reliable operation.

Overflow Protection

Built-in overflow ports prevent chamber overfilling during high-water conditions or float valve malfunction. Safe, fail-tolerant design.

System Integration

Works seamlessly with BIG or TIG pressure filters downstream. Water Box handles coarse screening, pressure filter provides fine filtration.

Key Features

Float Valve Assembly

Self-regulating float valve maintains consistent water level inside the chamber. As pump draws water out, the valve opens to allow more in, ensuring continuous flow without air entrainment. No external controls or power required.

  • Self-regulating level control
  • No power or controls needed
  • Prevents air entrainment

Overflow Ports

Built-in overflow ports provide fail-safe protection during high-water conditions or float valve malfunction. Water safely exits chamber before overfilling occurs. Simple, reliable safety feature.

  • High-water protection
  • Float valve backup
  • Fail-tolerant design

System Design: Water Box filters are typically installed at the water source (pond, canal, sump) with suction line running to pump. The large screen area and low intake velocity prevent debris accumulation and extend cleaning intervals. Pair with BIG or TIG pressure filters downstream for complete coarse-to-fine filtration protection.
