  1. Flojet Accumulator Tank
    $69.99
    The FLOJET Accumulator Tank gives you the best of both worlds! High flow when you need it and the ability to restrict the flow for sensitive situations. When the pump starts, liquid enters the reservoir compressing the bladder until the maximum pressure for the pressure switch is reached then the pump shuts off. When water is demanded, pressure in the air chamber forces liquid into the system. Pump stays off until the minimum pressure is reached on the switch. Then pump turns on, reducing cycling leading to longer switch and pump life. Learn More
