Because the controller varies speed rather than switching on and off, it removes the pressure flicker that owners notice most when a second tap opens.\u003c\/p\u003e\n\n\u003ch2\u003eFAQ\u003c\/h2\u003e\n\u003ch3\u003ePYS-450E or PYS-550E — which one?\u003c\/h3\u003e\n\u003cp\u003eCompare the head you need. Up to about 40 m of total lift (vertical rise plus pipe losses), the 450E is sufficient; above that, choose the PYS-550E at 50 m. Both share the same 8 m suction head and installation practice.\u003c\/p\u003e\n\u003ch3\u003eWill it work with a rooftop tank?\u003c\/h3\u003e\n\u003cp\u003eYes — it is designed for tank-fed systems and draws from up to 8 m suction head. For the best pressure, place the pump close to the tank outlet.\u003c\/p\u003e\n\u003ch3\u003eIs a pressure tank needed?\u003c\/h3\u003e\n\u003cp\u003eElectronic variable frequency control regulates pressure without a large vessel.
