1. Collect a sample of water. Make sure that the water is clear, odorless, and free of biological materials.
2. Test the pH. The ideal pH measurement is between 6.0 and 8.0.
3. Test the silica (SiO
2
) content. The silica content must be less than 0.0015% (15 parts per million [ppm]).
4. Test the water hardness. The result must be equal to or less than 0.006% (60 ppm).
5. Test the TDS concentration. The ideal range is 0.005% to 0.015% (50 ppm to 150 ppm).

A TDS level that is less than 0.005% (50 ppm) can harm waterjet parts and requires the use of
nonmetallic or stainless steel fittings.
 Treat water with a TDS level that is more than 0.015% (150 ppm) with reverse osmosis or consider
using deionized water.
CAUTION
A TDS value of less than 0.0005% (5 ppm) can damage stainless steel parts.
