5 Key Ways to Measure Your Waters pH levels
Wednesday, December 18, 2019

Do you know the pH level of your water? If you don't, testing your water levels can tell you whether your water is acidic or basic.

The pH scale ranges from 0-14 with lower numbers being more acidic and higher numbers being more basic (alkaline).

Although the EPA considers water pH an aesthetic quality, they recommend water supply levels should be a pH of 6.5 to 8.5.

Not sure how to test the pH of water? Keep reading to find out the different ways to measure your waters pH levels.

1. Look for Signs of High or Low pH

Again, the ideal pH of water is around 6.5 to 8.5. If you think you have unbalanced water, the first place you should look is your plumbing.

Signs of a low pH include blue or green staining on copper pipes or rust-colored stains on galvanized steel and cast-iron pipes. Pipe corrosion and sour-tasting water are also signs of a low pH level.

Signs of a high pH include scale buildup on faucets, a low water flow, and bitter water.

2. Use a pH Meter

When it comes to measuring the pH of water, using a probe and meter is by far the most accurate method. But before you can use a meter, you need to calibrate it.

Most testing meters require you to perform a pre-calibration first, which means testing a substance or solution with a known pH. Afterward, you can make the necessary adjustments for an accurate reading.

After collecting your sample, make sure it sits long enough for the temperature to stabilize. Submerge your meter and wait for the results.

3. Use Paper Test Strips

Look for test papers that have a pH indicator to tell you your exact number on the pH scale.

Dip the strip into the sample of your water and wait for the indicated amount of time mentioned in the instructions. After removing the strip you may have to wait a few minutes to see results. The color bar that develops on your paper tells you the pH of your water.

4. Using Red Cabbage Juice

This is a slightly unconventional method that relies on pigments called flavins. When mixed with other liquids, the cabbage juice works as a pH indicator by changing colors.

For instance, the cabbage juice turns red when mixed with something acidic and green when mixed with a basic substance.

5. pH Test Drops

This method works very much like the paper test strips. But instead of using paper, you add a few drops of the tester into your sample and the water changes color.

Again, you want to make sure the sample's temperature stabilizes first. After adding the drops to your sample, you should see results almost immediately. Compare the color of the sample to the chart provided.

Use These Ways to Measure Your Waters pH Levels

Testing the pH levels of your water ensures that they're in the range they should be for your needs. Use these ways to measure your waters pH levels and make sure they're where they need to be.

Now that you know how to measure the pH of water, which method should you use? Using a meter is the most accurate method on the list.
