Rain Bird PSRPL
Rain Water Harvesting Pump Control

The Rain Bird® PSRPL Rain Water harvesting control monitors the balance of available water in a rainwater harvesting system against the water level needed to assure proper pump performance.

Simple and efficient, the Rain Bird® PSRPL provides the pump control for rainwater harvesting, through the use of simple float controls, The Rain Bird® PSRPL synchronizes source water with pump requirements. If rainwater is available, the Rain Bird® PSRPL uses the stored water first, if no rainwater is available, the Rain Bird® PSRPL utilizes a domestic or alternate source to provide water to the pump during a run cycle.


Features

  • Float control (lower) is used to verify water is available during pump run cycle
  • Float control (upper) is used to supplement water supply through the use of a 24 VAC domestic solenoid valve. (Solenoid to be supplied by others)
  • Low pressure sensor protects the pump if the inlet water flow is restricted, reduced, or completely blocked
  • High temperature sensor protects the pump if the discharge is closed or blocked
  • All sensors and in-tank floats use safe 24 VAC power
  • Completely automatic and hands-free pump protection
  • Bridges the gap between 24 VAC lawn controllers and 110/220V pump motors
  • Serves as a pump start relay plus offers pump shut-down protection if source water is not available
  • One model works for all pumps from 3/4 hp to 5 hp
  • Terminal block wiring for easy installation

* National electrical code (nec) states all motors will be thermally protected from excessive “amperage draw.” Most motors under 2 hp are supplied with thermal protection from the motor manufacturer. For motors over 2 hp, code-compliant Rain Bird PSRB pump protection is recommended.

NOTE: Circuit breakers are never classified as motor protection

NOTE: Check with your local health department for regulations and requirements for backflow prevention.
