Compared with traditional bleed-off methods, the purge pump uses far less water while helping slow scale accumulation inside the reservoir and on media pads. The package includes the pump, mounting bracket, hose kit, a bracket screw and clear installation instructions tailored for compatible MasterCool models.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the purge pump prevent mineral deposits?\u003c\/h3\u003e\n\u003cp\u003eThe pump periodically expels a measured amount of water from the cooler reservoir to remove dissolved minerals before they concentrate and form scale.
