To ensure your Pentair 37297 Whole House Water Softening System is working efficiently, test your water hardness regularly. The user manual recommends testing at least twice a year using hardness test strips. These tests help you monitor the system's performance and allow for any necessary adjustments to maintain optimal water quality. You can purchase additional test strips from the Order Department; the order number is 38306 for a pack of 50 test strips.
