One small part that prevents a very expensive problem — chemical backflow and cross-line contamination.

The AquaVanta Pro Check Valve stops chemicals from flowing backward between lines in your proportioning system. Simple inline installation, 3/4" male NPT threading, and chemical-resistant construction make this a must-have in any multi-chemical soft wash setup. If you're running bleach and surfactant on the same manifold without check valves, you're one valve adjustment away from a contaminated tank.

Who This Is For

  • Contractors running multi-chemical proportioning systems
  • Anyone building or upgrading a soft wash manifold with multiple chemical lines
  • Operators who want to protect their chemicals and their equipment

Why It Matters

  • Prevents backflow between chemical lines — keeps bleach out of your soap tank and vice versa
  • Protects pump and proportioner from chemical cross-contamination
  • Simple inline installation — no special tools required
  • 3/4" male NPT — compatible with standard AquaVanta Pro proportioner setups

Specs

  • Size: 3/4" Male NPT
  • Installation: Inline, suction or discharge side
