Ideal pressure settings for optimal well performance?

Pressure Settings for Well Performance

When it comes to pressure settings, a general rule of thumb is to maintain a pressure that is within 10-20 PSI of the maximum allowable working pressure (MAWP) of the pump. For example, if the MAWP of the pump is 100 PSI, the operating pressure should be between 80-90 PSI to ensure optimal performance and longevity.

Well Yield and Pressure Relationship

The ideal pressure setting also depends on the well yield. A well with a high yield (typically exceeding 10 gallons per minute) may require a higher pressure setting to maintain a consistent flow rate. Conversely, a well with a low yield may require a lower pressure setting to prevent excessive pressure on the pump and well casing.

Pressure Tank Sizing

Proper pressure tank sizing is crucial to maintain a consistent pressure setting. A general rule of thumb is to size the pressure tank to hold at least 1/2 gallon of water for every gallon per minute of well yield. For example, a well with a 10 gallon per minute yield would require a 5-gallon pressure tank. This ensures that the pressure tank can accommodate the fluctuations in well yield and maintain a consistent pressure setting.
