McCANN 2 & 4.4 GALLON WATER BOOSTER SYSTEM This water booster system is great when low water pressure occurs. It is perfect for a carbonator that requires 20lbs. water pressure as a minimum. This important piece of equipment will maintain a 30lb minimum water pressure at all times. THIS DOES NOT HAVE AUTOMATIC SHUTOFF PROTECTION WHEN NO WATER OCCURS. SO YOU MUST UNPLUG IT IMMEDIATELY. Make sure your water filter isn’t ever clogged. Also a pump saver (part#903363) is highly recommended to avoid carbonator brass pump burnouts. Also a 50lb pre-set high pressure water regulator (part#961020) is recommended to assure non flooding of your carbonator tank, resulting in flat soda .
