How do I test the pH of a Home Master Artesian System?

In order to obtain an accurate pH reading you will need to use a good digital pH meter to test the water’s pH. Please do not use test strips or pH paper, for pH testing RO water. Test strips can be off by a full point or more when testing RO water because the water is so pure. They are notoriously inaccurate for pH testing even on higher TDS municipal water. City water will always measure an alkaline pH. Municipalities will not allow an acidic water to flow through the infrastructure as this will result in accelerated erosion, leaching of metals, costly repairs, leaks and lots of lawsuits.

Water has a limited ability to buffer against changes in pH so a small amount of something very acidic or very basic will have a large impact on the solution’s pH. This can very easily understood when you think about adding a few drops of lemon juice to a large glass of tap water and immediately detecting the change in taste – sour – which is how the tongue registers acidity. Its TDS will barely change but its pH will change substantially because of the lemon juice’s very low pH and water’s very limited ability to buffer against changes in pH. Water can even become acidified from the CO2 in the air, if the water is left to stand, and is one reason why we don't recommend our customers store jugs of drinking water in the fridge.

While the best way to test the pH is with a lab test, or a digital pH meter, an alternative method is testing for a surrogate indicator, such as TDS, using a TDS meter to see that the system is working correctly. Test the water as it leaves the RO membrane, and at the RO faucet, and then compare those readings to the tap water. Remember, the Home Master Artesian RO systems add calcium and magnesium minerals to increase the pH, and these pH increasing minerals show up in a TDS reading (please review the link below for comprehensive testing procedures).
