481167 WaterWorks Hydrogen Sulfide Water Test Strips, 30 foil Packed Tests

We are on well water and needed this to test what kind of filtration system we needed in our house, worked great and great value for money! Very easy to use and was very accurate! We were able to get a great system and our water is perfect

Well we have a Well and also a 4 pc Water Filtering system, due to Iron, Manganese and Hydrogen Sulfate! We wanted to retest as we need to change our filters and medium in the Iron/Manganese Tank, We were told to re-test so we could buy the exact medium needed. Well this test DID NOT CHANGE COLOR at all. Both at well outside, and inside after the water filtering system. NOTHING....So it does not work! WE Know for sure we have ROTTEN EGG smell and dirty water! So returning it for refund. My husband is a retired Residential Contractor so we know how to test! Use a plumber or well testing company

I saw a lot of bad reviews, but from what I can tell it’s from people who didn’t read or understand the instructions. This kit doesn’t change the colour of the test strip, the chemical on the end of the test strip will change the colour of the water so when the vial containing the test water is matched to the scale you can tell the percentage.

We do not have H2S. This test confirmed it. Neighbors water smells and the concentration was 0.5 ppm per this analysis

If you conduct the tests correctly you will receive accurate results. This test is so simple, but be sure to read and understand the directions before you start. The vial in my kit was undamaged surprisingly since most of my packages are pretty banged up most days. I would buy these strips again as I was happy with the product.

It didn’t work. After a dozen attempts, I got no reaction from the strips after using them as indicated, despite the subsequent determination of hydrogen sulfide. (perhaps it was out of date?) Also, I attempted calling their customer service and no one returned my call.

You might be smelling hydrogen sulfide (rotten egg) in your water. These test strips sounds like a great idea. Keep in mind, though, that your nose is at least an order of magnitude more sensitive than these strips. In other words, you might smell it but not be able to detect it using these strips. That's good and bad - you know you don't have massive concentrations of hydrogen sulfide (good) but you still have that stinky problem (unquestionably BAD). Carbon filters can help some but won't last long. The only true solution seems to be an oxidizing filter. Anyway, these strips might give you a quantitative answer if you have enough hydrogen sulfide for them to detect... But that wasn't so in my case.

I was looking forward to using this kit to test our water, but it arrived with a broken vial. When I returned it for a new one, the second one arrived with a broken vial. Disappointed.
