- Jet-Flo CBTB Cascade Effect Fountain Nozzles can produce a water effect with one of the highest water pressures.
- They do not require much water to achieve this effect.
- By mixing large amounts of air with water from the submersible pump, the pattern will appear extremely high-volume.
- CBTB nozzles are recommended for small and medium-sized displays in shallow pools.
