Hard Water Test Kit
1. Add the water you wish to test to the etched line on the vial.
2. Add 1 drop of solution, cover (with the palm of your hand or with the lid) and shake vigorously. If you see at least 1/4” of suds (bubbles) then you have completely soft water. If not, see #3.
3. Keep adding 1 drop at a time (shaking vigorously between drops) until you obtain 1/4″ of suds (bubbles) – this is soft water. Every drop of solution (after the first drop that doesn’t count) it takes to obtain 1/4” of suds is how many grains of hardness your water is.
(12 drops (after the first drop that doesn’t count) = 12 grains)
How will the test kit help you to know when you’ll need to regenerate?
Note: Example below is for the “ShowerStick” but can be similarly applied to our other WaterSticks.
After receiving your ShowerStick, you should first use the hard water test kit (included) to test your tap water to see what your actual water hardness is. After you install the ShowerStick, let the water run for a couple minutes then use the test kit and you’ll see that your water is now soft. (Don’t test the water right after installing the WaterStick or after regenerating because it will give you a false positive since the salt will test as a mineral.) After you take a couple more showers, test the water again. Continue to do this until the test kit starts to show the water is no longer soft then you’ll need to regenerate your ShowerStick. If you determine it needs to be regenerated after every 5 showers and you take 5 showers per week then you can make a mental note to do it every Monday for example.
Water districts measure water hardness in “ppm” (parts per million). Many water softening companies and hard water test kits (including ours) measure water hardness in “grains”.
grains x 17.1 = ppm
ppm/17.1 = grains
12 grains = 204 ppm
