Thanks to the integrated pressure switch, the system operates automatically: the pump starts when a tap is opened and stops once it is closed. This eliminates the need for an accumulator tank and allows up to four outlets to be supplied simultaneously.<\/p>\n<p>The durable internal components, including EPDM valves and a Santoprene diaphragm, ensure chemical resistance, long lifespan, and reliable performance in both fresh and saltwater.
