Introduction
The LifeStraw Peak Series Gravity Water Purifier is a portable, high-capacity water purification system designed for outdoor activities, emergency preparedness, and travel. It effectively removes viruses, bacteria, parasites, and microplastics from water sources, providing safe drinking water. This system operates without the need for pumping or external energy, utilizing gravity for a flow rate of 30 liters per hour.
Key features include an 8-liter dirty water bag, an ultrafilter membrane with a lifetime capacity of 18,000 liters, and a custom backwash syringe for maintenance. The system is constructed from BPA-Free materials.

Setup Instructions
- Unpack Components: Remove all items from the packaging and ensure all components listed in the Components Overview section are present.
- Connect Filter to Hose: Attach the ultrafilter membrane purifier to one end of the hose. Ensure a secure connection.
- Connect Hose to Bag: Attach the other end of the hose to the outlet port of the 8-liter dirty water bag. The bag features a leakproof cap.
- Prepare for Filling: Ensure the twist on-off mechanism on the filter is in the 'off' position to prevent water from flowing out prematurely.

Operating Instructions
- Fill Dirty Water Bag: Open the top of the 8-liter bag and fill it with untreated water from your source. Securely close the bag.
- Hang the Bag: Use the provided hang strap and carabiner to suspend the filled dirty water bag from a sturdy object, such as a tree branch, at a height above your collection container. Ensure the filter and hose hang freely.
- Collect Purified Water: Place a clean container (e.g., bottle, cup) beneath the filter's outlet. Turn the twist on-off mechanism on the filter to the 'on' position. Gravity will draw water through the filter, and purified water will flow into your container.
- Monitor Flow: The system has a flow rate of 30 liters per hour. If the flow rate decreases significantly, refer to the Maintenance section for backwashing instructions.
- After Use: Once you have collected sufficient water, turn the twist on-off mechanism to the 'off' position.

Maintenance
Regular maintenance is crucial to ensure the longevity and effectiveness of your LifeStraw Peak Series Gravity Water Purifier.
Backwashing the Filter
Backwashing helps to clear trapped particles from the filter membrane, restoring flow rate. It should be performed regularly, especially if the flow rate decreases.
- Disconnect Filter: Detach the ultrafilter membrane purifier from the hose.
- Prepare Syringe: Fill the custom backwash syringe with clean, purified water.
- Backwash: Attach the syringe to the outlet end of the filter (the end where clean water exits). Firmly push the plunger to force clean water back through the filter. Repeat this process several times until the water expelled from the dirty water inlet appears clear.
- Rinse: After backwashing, rinse the exterior of the filter with clean water.
Storage
After each use, especially before long-term storage:
- Perform a thorough backwash.
- Allow the filter to air dry completely.
- Store all components in a cool, dry place, away from direct sunlight.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Slow or No Water Flow | Filter membrane is clogged with sediment or debris. | Perform backwashing using the custom syringe as described in the Maintenance section. Ensure the dirty water bag is elevated sufficiently. |
| Water Leaks from Connections | Connections are not secure or O-rings are damaged. | Ensure all hose and filter connections are tightened properly. Inspect O-rings for damage and replace if necessary. |
| Water Tastes Unusual | Filter may be new (initial taste) or water source has high mineral content. | Flush the filter with a few liters of water before first use. The filter removes biological contaminants, not chemical tastes or high mineral content. |
