ZeroWater pitchers are designed to provide you with pure, great-tasting water, but proper assembly is essential to get the most out of your pitcher. Whether you’re unboxing your ZeroWater pitcher for the first time or replacing the filter, this guide will walk you through the process step by step to ensure everything is set up correctly.
What’s in the Box?
Before you begin, make sure you have all the necessary components:
- ZeroWater pitcher (varies by size)
- ZeroWater filter
- Pitcher lid
- Reservoir with TDS meter
Step 1: Wash the Pitcher Components
Before assembling your pitcher, it’s important to give all the components (except the filter) a quick wash:
- Use warm, soapy water to clean the reservoir, pitcher, and lid.
- Rinse thoroughly to ensure no soap residue remains.
- Dry the components with a clean towel or allow them to air-dry.
This step removes any dust or debris from packaging and ensures your water remains pure.
Step 2: Prep the ZeroWater Filter
The ZeroWater filter is the heart of the pitcher, so preparing it correctly is crucial:
- Remove the filter from its packaging.
- Check the black O-ring at the base of the filter to ensure it’s securely in place. This prevents leaks during use.
- Do not rinse or soak the filter. ZeroWater filters are ready to use right out of the box.
Step 3: Attach the Filter to the Reservoir
Now it’s time to install the filter:
- Screw the filter into the reservoir’s threaded hole.
- Tighten it firmly, but don’t overtighten. A snug fit ensures a proper seal without risking damage to the filter.
- Check for any gaps or misalignment. The filter should sit flush with the reservoir’s bottom.
Step 4: Assemble the Pitcher
With the filter in place, it’s time to put the pitcher together:
- Place the reservoir (with the filter attached) inside the pitcher.
- Align the reservoir’s edges with the pitcher to ensure a secure fit.
- Snap the lid onto the reservoir. Most ZeroWater lids are designed to fit snugly, so you may need to press down firmly until you hear a click.
Step 5: Fill the Reservoir
Now your pitcher is ready for use:
- Fill the reservoir with cold tap water.
- Allow the water to pass through the filter completely. This may take a few minutes, as ZeroWater filters are designed to remove all detectable TDS (Total Dissolved Solids).
- Use the included TDS meter to test the filtered water. The reading should be 000 ppm, indicating pure water.
Step 6: Store and Maintain Your Pitcher
Once your pitcher is assembled and filled, here are a few tips to ensure long-lasting performance:
- Refrigeration: Store your pitcher in the fridge to keep water cold and fresh.
- Cleaning: Clean the pitcher and reservoir every few weeks to prevent buildup.
- Filter Replacement: Monitor the TDS levels regularly. Replace the filter when the reading exceeds 006 ppm.
Common Questions About ZeroWater Pitcher Assembly
1. Do I need to soak the filter before use?
No. ZeroWater filters are prepped and ready to use without soaking.
2. Why is water filtering slower than expected?
This is normal for ZeroWater filters, as they thoroughly remove impurities. Ensure the filter is installed correctly, and avoid overfilling the reservoir.
3. Can I use hot water in the pitcher?
No. Always use cold or room-temperature water. Hot water can damage the filter and compromise performance.
4. How tight should I screw in the filter?
The filter should be securely hand-tightened to prevent leaks, but avoid over-tightening, which can damage the threads.
5. What if my filter doesn’t fit properly?
Double-check the O-ring and threads for any issues. If the filter still won’t fit, contact ZeroWater customer support for assistance.
