Pressure Tanks

A pressure tank stores pressurized water so the pump doesn’t start every time you open a tap. Correct sizing reduces pump short-cycling and wear.

What to look for

  • Drawdown that gives adequate pump run time (use our calculator)
  • Pre-charge set ~2 psi below cut-in
  • Bladder/diaphragm quality and warranty

Limitations

  • Tank sizing interacts with pump flow and pressure settings — size the system as a whole.
