| Reverse osmosis system | $650 |
| Water test | $0 |
| Total | $2,450 |

What customers ask a water treatment tech
Do I really need a softener?
A water test helps decide. Share the results honestly.
How often do filters need changing?
Give the manufacturer's guidance in the notes.
Will soft water taste different?
Some people notice; mention it.
Tips for your water treatment tech business
