- Long Filter Lifespan: Filters last up to 6-12 months depending on the stage.
- Durable Construction: Built with quality materials to prevent leaks and cracks.
2. Important Notes & Warnings
- TDS Warning: This under sink water filter system does NOT reduce Total Dissolved Solids (TDS). Essential minerals are dissolved solids and will not be removed, so TDS meter readings will not drop.
- Water Source: Designed specifically for municipal tap water and cold water sources ONLY. Not suitable for well water or hot water.
- Pre-filtration for Well Water: If using well water, ensure it has passed through a pre-filtration system.
- Faucet Compatibility: Suitable for faucets with 1/2" or 3/8" FEMALE NPT thread. Contact customer service for free quick-connect faucet fittings if needed.
- Activated Carbon: The activated carbon is made from natural coconut shells. Confirm no allergies before use.
- Vacation Storage: Before going on vacation, place filters in separate sealed plastic bags and store them in your refrigerator (NOT the freezer) to keep them fresh for up to 30 days.

4. Setup and Installation
The Waterdrop WD-TSA-UF system is designed for quick and easy installation, typically taking less than 3 minutes. No plumber is needed.
Step-by-Step Installation:
- Mount the Filter Head:
- Choose a suitable location under your sink, ensuring the filter is mounted at least 2 inches higher than the ground for easier filter changes.
- Use the provided assistant label as a template to mark the drilling points on the wall.
- Drill pilot holes and install the screws, leaving enough space for the filter head to hang securely.
- Hang the filter head onto the installed screws.
- Connect the Water Supply:
- Shut off the main cold water supply to your sink.
- Turn on the kitchen faucet to release any remaining water pressure.
- Disconnect the cold water pipe from the cold water supply valve.
- Connect the inlet hose (marked 'IN' on the filter head) to the cold water supply valve. Use the appropriate 3/8" or 1/2" converter if necessary. Ensure all connections are tight to prevent leaks.
- Connect the outlet hose (marked 'OUT' on the filter head) to your faucet's cold water inlet.
- Install Filter Cartridges:
- Align each filter cartridge (PP, GC, UF) with its corresponding slot on the filter head.
- Insert and twist each cartridge clockwise until it locks securely into place.
- Flush the System:
- Slowly turn on the main cold water supply.
- Open your kitchen faucet and flush the filter system for 5 minutes to remove any carbon fines and air from the system before first use.

5. Operating Instructions
Once installed, operating your Waterdrop WD-TSA-UF system is straightforward:
- Filtered Water: Simply turn on your cold water faucet to dispense filtered water.
- Flow Rate: The filtration process may slightly reduce the water flow rate compared to unfiltered water. This is normal and indicates the system is actively filtering.
- Initial Use: Always flush the system for 5 minutes before initial use or after any filter replacement.
6. Maintenance
Regular filter replacement is crucial for optimal performance and water quality.
Filter Lifespan & Replacement:
- PP Filter (WD-10PP): Replace every 6 months. (Search for B0CM8MHWNT)
- GC Filter (WD-10GC): Replace every 8-12 months. (Search for B0CM8KV1M9)
- UF Filter (WD-10UF): Replace every 12 months. (Search for B0D1RBH4QX)
Replacement is simple with the twist-and-lock design, taking only 3 seconds per filter.

7. Troubleshooting
If you encounter any issues with your Waterdrop WD-TSA-UF system, consider the following common solutions:
- Low Water Flow:
- Check if the filter cartridges are due for replacement. Clogged filters can significantly reduce flow.
- Ensure the cold water supply valve is fully open.
- Verify that all hose connections are secure and not kinked.
- Leaks:
- Tighten all connections, especially where hoses connect to the filter head and water supply.
- Ensure filter cartridges are properly seated and twisted into place.
- If leaks persist, contact customer support.
- Unpleasant Taste/Odor:
- Flush the system for an extended period (10-15 minutes) to remove any residual carbon fines.
- Replace the GC filter if the taste/odor issue persists, as this filter is primarily responsible for taste and odor reduction.
Understanding TDS:
The Waterdrop WD-TSA-UF system is designed to retain beneficial minerals, which contribute to TDS. Therefore, a high TDS reading does not necessarily indicate poor water quality. The system focuses on removing harmful impurities while keeping essential minerals.
Video: An informational video explaining what TDS (Total Dissolved Solids) really is and why a low TDS reading does not always equate to good water quality, demonstrating that beneficial minerals contribute to TDS.
Image: An infographic explaining that low TDS does not necessarily mean cleaner water. It illustrates that harmless minerals like Calcium, Magnesium, Sodium, and Potassium raise TDS, while impurities like Chlorine, bad taste, and odor may not change TDS but affect water quality. The Waterdrop filter targets impurities while keeping healthy minerals.
Image: A graphic explaining that TDS is not a professional water quality measure and that the system does not remove essential minerals, thus not lowering TDS. It provides examples of TDS levels in various beverages like milk, juice, cola, and mineral water.
