Usage

The Inline 400 with Expansion Tank is designed to increase water pressure in homes, cottages, irrigation systems, and light commercial buildings supplied by municipal water, cisterns, or storage tanks. The included 2-liter expansion tank stores a small volume of pressurized water, allowing minor water demands to be met without immediately starting the pump. This reduces cycling, minimizes pressure fluctuations, and extends pump life. The system automatically starts when pressure drops or flow demand is detected and incorporates protection against dry running, overheating, and abnormal voltage conditions.
