Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of your Geekpure 5-Stage Reverse Osmosis Drinking Water Filter System. This system is designed to provide high-quality filtered water by reducing various contaminants down to 0.0001 micron, including arsenic, lead, fluoride, mercury, cadmium, and heavy metals, while also improving water taste and odor.
For optimal performance and longevity of your system, please read these instructions carefully before proceeding with installation or use.

Setup and Installation
The Geekpure RO system is designed for under-sink installation and features quick connect fittings and color-coded tubing for a straightforward DIY experience. Basic plumbing knowledge and tools are recommended.
Pre-Installation Checklist:
- Water Pressure: Ensure your feed water pressure is between 40 - 100 PSI.
- Temperature: Operating temperature should be 40-110°F (5-45°C).
- pH: Water pH should be between 3.0 - 11.0.
- Max TDS: Maximum Total Dissolved Solids (TDS) should not exceed 1000 PPM.
- Space: Verify sufficient space under your sink for the main unit (14.2"L x 9.5"W x 18.1"H) and the 2.8-gallon storage tank.
Installation Steps:
- Faucet Installation:
Drill a hole (approximately 1.5 inches in diameter) on your countertop for the faucet. Ensure the hole is positioned conveniently. Secure the faucet using the provided base plate, rubber washer, plastic washer, lock washer, and nut. Use Teflon tape on threaded connections as instructed.
Figure 2: Faucet installation diagram, showing components and dimensions.
- Connect Feed Water:
Install the feed water diverter valve to your cold water line. Connect the appropriate color-coded tubing from the diverter valve to the system's inlet.
- Connect Drain Saddle:
Attach the drain saddle to the drain pipe under your sink. Connect the waste water tubing from the RO system to the drain saddle.
Figure 3: Main RO unit with drain water connection point highlighted.
- Install Filters and RO Membrane:
Ensure all filters (sediment, granular carbon, carbon block) are correctly seated in their housings. Install the RO membrane into its housing. Refer to the filter stage diagram for correct order.
Figure 4: Five stages of filtration and filter lifetimes.
- Connect Storage Tank:
Connect the storage tank to the system using the tank ball valve and appropriate tubing.
- Final Connections:
Connect the remaining color-coded tubing between the filter stages, RO membrane, and faucet as per the system diagram. Ensure all quick-connect fittings are pushed in completely and secured with blue locking clips.
- Leak Check:
After completing all connections, slowly turn on the feed water. Carefully check all connections for leaks. It is recommended to wait until the entire system is pressurized (including the storage tank and faucet) and re-check for any leaks before leaving the installation site. Check again after a few hours, and then periodically for a few days to ensure no slow leaks develop.

Operating Instructions
Initial System Flush:
After installation, the system requires an initial flush to remove any carbon fines and air from the filters. This is a critical step to ensure optimal water quality.
- Allow the storage tank to fill completely. This may take several hours depending on water pressure.
- Once the tank is full, open the RO faucet and allow all the water from the tank to drain completely.
- Repeat this process for a second tank fill and drain cycle. The first two tanks of water produced should be emptied and not consumed. It is normal for some black carbon fines to appear in the water during this initial flush.
- After the second flush, the system is ready for use.
Normal Operation:
The system operates automatically. When water is drawn from the faucet, the pressure in the storage tank drops, and the system begins to produce more filtered water to refill the tank. The RO process produces a small amount of wastewater, which is discharged through the drain line.

Maintenance
Regular maintenance, primarily filter replacement, is essential for the continued performance and water quality of your RO system. The replacement filters are universally compatible and standard size.
Filter Replacement Schedule:
- PP Sediment Filter (1st Stage): Replace every 6-12 months. Reduces silt, sand, dirt, and sediment.
- Granular Carbon Filter (2nd Stage): Replace every 6-12 months. Reduces chlorine, odors, and taste.
- Carbon Block Filter (3rd Stage): Replace every 6-12 months. Reduces chlorine, odors, and taste.
- RO Membrane (4th Stage): Replace every 15-20 months. Reduces total dissolved minerals.
- Post Carbon Filter (5th Stage): Replace every 12-15 months. Improves water for refined taste.
Note: Filter life may vary based on local water quality and usage.
Filter Replacement Procedure:
- Turn off the feed water supply to the RO system and close the tank ball valve.
- Open the RO faucet to relieve pressure in the system.
- Use the provided housing wrench to unscrew the filter housings.
- Remove old filters and dispose of them properly.
- Clean the inside of the filter housings.
- Insert new filters, ensuring O-rings are properly seated.
- Screw the housings back on tightly using the wrench. Do not overtighten.
- Slowly turn on the feed water supply and open the tank ball valve.
- Check for leaks. Flush the system as described in the "Initial System Flush" section if replacing multiple filters or the RO membrane.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Water Leaks | Loose fittings, improperly seated O-rings, damaged components. |
|
| No Water from Faucet / Very Slow Flow | Feed water supply off, tank valve closed, clogged filters, low water pressure, kinked tubing, air in system. |
|
| Poor Water Taste or Odor | Expired carbon filters, expired RO membrane, initial carbon fines. |
