Are you curious about what type of water you have?

It helps to know if your water is soft or hard or somewhere in between when it comes to household concerns like laundry and maintenance. What type of detergent should you use? Do you need a water softener? Will your water heater be more prone to break down from mineral build-up? Your local plumber might be able to give you a rough idea of the water type based on a “grains per gallon” measurement. The scale of hardness, as defined by the Water Quality Association, is as follows:

Soft: 0-1 grains per gallon (gpg)
Slightly Hard: 1-3.5 gpg
Moderately Hard: 3.5-7.0 gpg
Hard: 7.0-10.5 gpg
Very Hard: over 10.5 gpg

But there’s also a simple and cheap test you can do at home. It costs just 99 cents and takes about 15 seconds: the Water Test Strip from Diaper Junction (aff):

It consists of a white paper test stick and a color chart which is printed right on the package:

The water test strip from Diaper Junction is a cinch to use. Stick it under running water for 1 second. Shake off the excess water and then wait 15 seconds. Read the results by comparing the wet test strip to the color chart on the package.

My test result was right in the middle – the brown color equates to roughly 7 grains per gallon. According to the above scale, our water is “moderately hard.”

    Thanks for the test strip resources! I’ve been really curious about our water because I assume it’s hard but don’t know the exact number. It’s great that Diaper Junction gives them away to customers because knowing what type of water you have makes a difference with diaper laundrry.
