What is the acceptable delta pressure for the softener?

The acceptable delta pressure for the softener is recognized as 10 psi. This value is significant because it indicates the optimal difference in pressure that helps maintain the efficiency of the water softening system. A delta pressure that falls within this range ensures that the system functions effectively, allowing it to adequately exchange ions and remove hardness from the water.

If the pressure difference is too low, it may indicate a problem with the flow rate or even potential blockages, compromising the softening process. Conversely, a higher delta pressure might signify an issue with the system that's affecting performance. Therefore, maintaining a delta pressure of 10 psi provides a balance that supports optimal operation and longevity of the softener, allowing for effective removal of hardness while minimizing risks of system stress.
