RL25U Multi-Purpose Pump

This submersible multi-purpose pump is designed for clear water transfer applications and household water removal. The pump is for use with water only.

Do NOT use this pump for:

  • Transferring potable water
  • Effluent or sewage applications
  • Applications where debris (gravel, sand, etc.), abrasives, or corrosives are present
  • As a pond pump, or for pumping seawater
  • Sprinkler systems—this pump does not deliver enough pressure for sprinkler applications
  • Locations classified as hazardous according to the National Electrical Code (ANSI/NFPA)

The pump motor is equipped with an automatic resetting thermal protector, and may restart unexpectedly. Thermal Protector tripping is an indication of motor overloading or overheating.

  • If the power disconnect is out of sight, lock it in the open position and tag it to prevent unexpected application of power.


High voltages capable of causing severe injury or death by electrical shock are present in this unit.

  • To reduce risk of electrical shock, disconnect power before working on or around the system. More than one disconnect switch may be required to de-energize the equipment before servicing.
  • Connect this pump to a circuit equipped with a ground fault circuit interrupter (GFCI) device if required by code.
  • This product is supplied with a grounding conductor and grounding-type attachment plug. To reduce risk of electric
    shock, be certain that it is connected only to a properly grounded grounding-type receptacle. Do not remove the third prong from the plug. The third prong is to ground the pump to help prevent possible electric shock hazard.
  • Check electrical outlets with a circuit analyzer to ensure power, neutral, and ground wires are properly connected. If not, a qualified, licensed electrician should correct the problem.
  • Wire pump system for correct voltages.
  •  The pump has been evaluated for use with water only. Pum should only be used with liquids compatible with pump component materials. If the pump is used with liquids incompatible with the pump components, the liquid can cause failure to the electrical insulation system resulting in electrical shock.
  • Do not use the power cord for lifting the pump.
  • Do not use an extension cord.


Risk of bodily injury, electric shock, or property damage.

  • This equipment must not be used by children or persons with reduced physical, sensory, or mental abilities, or lacking in experience and expertise, unless supervised or instructed. Children may not use the equipment, nor may they play with the unit or in the immediate vicinity.
  • Equipment can start automatically. Always unplug the pump power cord and disconnect the electrical power before servicing the pump or switch.
  • An inoperative or malfunctioning pump could lead to flooding, resulting in personal injury or property damage.
  • In applications where property damage and/or personal injury might result from an inoperative or leaking pump due to power outages, discharge line blockage, or any other reason, an automatic back-up system and/or an alarm should be installed.
  • Do not run the pump dry. If run dry, the surface temperature of the pump will rise to a high temperature that could cause skin burns if touched and will cause serious damage to the pump.
  • Do not oil the motor. This unit is permanently lubricated. Oiling is not required. The pump’s motor housing is sealed. Do not open the sealed portion of the unit or remove housing screws. Opening the motor housing could cause serious electric shock and/or permanent damage to the pump.
  • Operation of this equipment requires detailed installation and operation instructions provided in this manual for use with this product. Read entire manual before starting installation and operation. End User should receive and retain manual for future use.

  1. Do not plug in the pump until all plumbing connections are complete and pump is secure.
  2. Connect a garden hose directly to the 3/4″ discharge or connect 1-1/4″ MNPT threaded pipe or hose to the 1-1/4″ FNPT adapter included.
    NOTE: The Discharge Adapter is a two piece design. To use with a garden hose, unscrew the reducer from the elbow. The Adapter can also be rotated on the pump flange to allow the hose to be placed in either a vertical or horizontal position. When making these adjustments, be careful not to lose or damage the seals.
  3. Place the pump vertically on a solid surface in the water to be removed. The water should be at least 1/2” deep. If the surface consists of dirt or sand, place the pump on a flat surface such as a piece of wood or metal to prevent it from being clogged.
  4. Position the free end of the hose or pipe where the water is to be relocated.
  1. Plug the power cord directly into an electrical outlet. To reduce the risk of electric shock, be certain it is connected only to a properly grounded grounding-type receptacle. A ground fault circuit interrupter (GFCI) is recommended and may be required by code.
    IMPORTANT: Check the pump label for proper voltage required. Do not connect to voltage other than that shown.
  2. Unplug the unit as soon as the pump stops pumping water or the suction sound changes to prevent the pump from running dry. Do not let the unit run dry (without liquid). It is designed to be cooled by pumping fluid. The seal may be damaged and the motor may fail if the pump is allowed to run dry.
  3. If the pump does not operate properly, consult the Troubleshooting chart in this manual. If trouble cannot be located with the steps shown, consult your pump dealer or call 1-888-885-9254.
