Water results may not always align perfectly with a single color. In that case, choose the closest match or estimate a value between two shades for a more accurate reading.

Test strips are best used within 6 months after opening. When sealed and stored properly, they can remain stable for up to 2 years.

Store your kit in a cool, dry environment away from direct sunlight, heat, and moisture. Always ensure the container is tightly sealed after use.

No. Each strip is designed for a single use only. For accurate and reliable results, always use a fresh strip for every test.

Read the result strictly at 48 hours:

• Yellow at 48 hours = Negative
  
• Green at or before 48 hours = Positive
  
• Any color change after 48 hours = invalid and should be ignored

It is not a valid result. Only the 48-hour window matters. Any change after that point is due to overgrowth and should not be interpreted.

No. Test pads should not appear pre-reacted or unusually tinted before testing. This can indicate humidity exposure or improper storage, and the strip may no longer give reliable results.

Once opened, strips are generally reliable for up to 6 months if stored properly in a sealed container, away from moisture and heat.

Not currently. The bacteria testing component is only available as part of the Complete Drinking Water Test Kit.

Yes. High humidity, improper sealing, or extreme temperatures can affect strip and vial performance, so proper storage is important for accurate testing.

If a bacteria result is positive within the valid reading time, it is recommended to take immediate precaution and consider professional confirmation depending on your local water source and risk level.

The best kit depends on your water source, concerns, and home setup. City water users and private well owners often require different testing panels because the contamination risks are different.

Most laboratory reports are completed within 3–5 business days after your samples arrive at the lab. Certain advanced analyses may require additional processing time depending on the contaminants being tested.

AnswerWater can contain thousands of possible compounds and contaminants, so no single panel can test absolutely everything. Flode lab kits are designed to focus on the most relevant and high-priority contaminants commonly found in drinking water.

No. Flode lab kits are designed for simple at-home sample collection. Each kit includes clear instructions to help you collect and return your samples correctly.

Yes. Flode partners with certified laboratory facilities that follow recognized testing and quality control standards for water analysis.

Certain contaminants require more detailed analysis or additional quality-control verification to ensure accurate readings. This can occasionally extend turnaround times.

Yes. Your laboratory results remain private and are only accessible to you unless you choose to share them.
