Data Upload
Get your assembly data ready for Autofill
To utilize the Autofill feature, previous assembly data must be uploaded to the system. This data must follow a strict format—any deviation will prevent a successful upload and require the file to be cleaned before importing. Please refer to the provided example file to ensure your data meets the required structure and avoids additional cleanup.
If you do not have existing assembly data, you can manually enter assemblies in the field as you test. These entries will be saved and made available for future Autofill use.
Data Upload Guidelines
- The file must be in Excel (.xlsx) format
- The file must exactly match the format of the provided example. If the file does not meet the required format, it will need to be cleaned—either by the submitting company or by WTM Solutions.
- Data cleaning performed by WTM Solutions will incur a service fee. The file will be reviewed first, and an estimated cost will be provided to reformat the data to meet the required specifications.

What are Testers Saying?
Let me start off by saying Wow!
Wow this test kit has made my life as a tester easier, faster, and more efficient. While it should be no surprise that this kits fit and finish would be great, I’ll say it anyway, its great! I love my 845, 5 valve analog kit and you may think, there will always be a place for analog kits, and you may be right. However, theres no denying that the world is moving towards all things digital and the 855 has met that need very well. First off, holds well, with a good fit in your hand while testing. Not a heavy or bulky kit at all which is a plus for me testing all day. There’s barely a learning curve at all and I’d even argue its ease of use could actually aid in teaching backflow testing to new testers. As much as I love my 845, (did I say that already?) the benefits of going digital with the 855 has sped me up and made the back end, paperwork side of testing, a breeze to get through. No more “where did I put my pen?” and no more wet papers being filled out in the field. I cruise through my data collection using the speak-to-text on my phone to call out make, model and serial numbers as well as any other pertinent info, then I’m on to testing faster than I had ever been before. Repeat tests or coming back to test again after repairs goes even quicker. I’m adapting with the times and have gone digital and I’m not looking back. I’m stoked I chose the Midwest Instrument 855!
