In-line fluid storage tank system

A system comprising:

• a storage tank;
• a valve switch system connected to the storage tank, having a one-way valve interface to couple to an on-premise supply line that provides a pressurized flow of fluid to a consumer premises, and having an interface to a pump coupled to the storage tank, the valve switch system operable to,
• when the supply line provides the pressurized flow of fluid, route the fluid from the supply line to an intake interface of the consumer premises passing through the storage tank;
• when the supply line provides the pressurized flow of fluid, route the fluid from the supply line to the intake interface bypassing the storage tank;
• and
• when the supply line provides a reduced pressure flow of fluid, pressurize the storage tank with the pump, and route the fluid from the pressurized storage tank to the intake interface.

A method comprising:

• configuring a valve switch system coupled to a water storage tank to output water to an intake interface of a consumer premises, including one of
• configuring the valve switch system to receive water from an on-premises water supply line when the water supply line provides a pressurized water supply, and route the water from the water supply line to an intake interface of the consumer premises, passing through the water storage tank;
• configuring the valve switch system to receive water from an on-premises water supply line when the water supply line provides a pressurized water supply, and route the water from the water supply line to the intake interface bypassing the water storage tank;
• or
• configuring the valve switch system to pressurize the water storage tank with compressed gas when the water supply line provides a reduced pressure water supply, and route water from the pressurized water storage tank to the intake interface;
• and
• routing water in accordance with the configuration of the valve switch system.
