What is the IK159?
The RAINPOINT IK159 is an automatic indoor drip irrigation pump designed to draw clean cold water from a water container and deliver it directly to plants through a drip irrigation system.

- HOW OFTEN: Sets the watering interval.
- HOW LONG: Sets the watering duration and includes an OFF position.
The pump also includes a MANUAL button for starting or stopping watering without changing the preset schedule.
The built-in rechargeable battery is charged through the USB-C port using a 5V / 1A power source.

Before You Start
For reliable operation, check the following before setting up the IK159.
1. Charge the pump before use
Connect the included USB-C cable to the pump and use a 5V / 1A USB power adapter.
The power indicator provides charging and battery status information:
- Breathing green: Charging
- Yellow: Low battery
- Red flashes twice: Battery depleted; the pump cannot operate
2. Use clean cold water only
Keep the inlet filter installed to help prevent impurities from entering the pump and tubing.
3. Position the pump correctly
Place the pump at or above the reservoir water level.
Do not place the pump below the water level. Correct placement helps prevent siphoning, backflow, leakage, or unintended watering.
4. Keep the height difference within 6.6 ft (2 m)
The recommended maximum installation height difference is: ≤ 6.6 ft (2 m)
5. Check the IN and OUT connections
Connect the 1/6" (4 mm) tubing firmly to the water inlet and outlet ports.
Loose or incomplete tubing connections may cause leakage.
6. Install the anti-siphon valve correctly
Install the anti-siphon valve on the outlet tubing near the pump.
Make sure the valve follows the marked water-flow direction.
7. Keep the inlet filter submerged
Attach the filter to the inlet tubing and place it inside the water container.
8. Release air before installing the end plug
Allow water to flow from the end of the tubing before installing the end plug. This helps release trapped air from the irrigation line.
9. Test the system before regular use
For a one-time test:
- Set HOW OFTEN to ONE TIME
- Set HOW LONG to a watering duration other than OFF
Alternatively, use the MANUAL button to test watering.
Check all tubing connections and fittings for leaks before regular operation.
