Coming soon: $29, credited toward your treatment kit

Not sure it is the well? Test at home first.

Water test strips plus a 48-hour coliform bottle, read in your own kitchen, no lab and no mailing. Enter the results here and you get a diagnosis and a dose level, and the $29 comes off your treatment kit. If you already have symptoms, you do not need this step: the treatment kit carries its own before-and-after test.

Already have a test result? Set your dose from it.

Four questions. The answers pick the dose level inside the manufacturer's published 20 to 50 ppm shock range, and your well record then sets the sachet count.

  • Did a water test come back positive for coliform or E. coli?
  • Is there orange or black slime in the toilet tank, or rust staining on fixtures?
  • Does the cold water smell like rotten eggs?
  • Did a previous shock treatment wear off within a few months, or leave no residual on the test strip?

No newsletter and no drip sequence. One email on launch day, and your address is used for nothing else.

Well water should be tested at least once a year, and any change in taste, smell, or clarity is a reason to test now. While the kit is coming, our guides cover the problems a test usually finds: coliform bacteria, iron bacteria, and rotten egg smell.
