What is a VFD / constant pressure controller? Instead of cycling your pump on and off like a traditional pressure switch, a VFD adjusts the pump speed to maintain steady pressure at all times. The result is consistent water pressure whether you're running one faucet or five — and reduced wear on your pump motor and saving on power usage.
