A method of unloading a modular home from a trailer includes positioning a modular home on a trailer bed. The modular home includes a first housing portion having a first vertical edge coupled to a second vertical edge of a second housing portion by a hinge, and the first and second housing portions are arranged longitudinally on the trailer. The method further includes rotating the first and second housing portions about the hinge such that the first and second housing portions overhang from the sides of the bed, forming first and second overhanging portions. The method further includes coupling at least one of (1) a first horizontal edge of the first housing portion to a second horizontal edge of the second housing portion, or (2) a third vertical edge of the first housing portion to a fourth vertical edge of the second housing portion upon completion of the rotating.

A constant pressure system includes a pressure vessel with a vapor-liquid mixture used to provide pressure forces instead of compressed air that is typically used. The vapor-liquid mixture can be a number of substances, such as nitrous oxide, so long as the mixture exists in both the liquid and vapor phases. Importantly, the vapor-liquid mixture must maintain a constant pressure during the dispensing of fluids from the tank, so that the fluids are dispensed at the same constant pressure. As a result, the fluids within the tank can be dispensed at the same pressure as that of the vapor-liquid mixture within the tank, or scaled to a higher or lower pressure value through the use of a pressure-converter valve within the system.

A controller for a well system automatically profiles the system, detects a pre-charge of an associated pressurized storage tank, and automatically configures pressure-based control of a pump based on the detected pre-charge. The controller determines the pre-charge of the pressurized storage tank while the tank is connected to the system. While monitoring a system pressure, the controller activates the pump to initiate a filling operation of the pressurized storage tank. The controller analyzes a change in system pressure during the filling operation to determine the pre-charge of the pressurized storage tank. With the pre-charge determined, the controller automatically configures pressure settings for pressure-based control of the pump.

Water storage systems are provided to facilitate storing water for use when a primary source of water becomes unavailable. These water storage systems can be configured to connect into a home's or a building's plumbing to enable the water tanks of the system to be easily filled and regenerated. The water storage systems may include a support system to maximize space utilization and to possibly provide seismic protection.

The present invention relates to a multi-purpose water tank, and more specifically to a multi-purpose water tank, which enables water accommodated in the water tank and a liquid chemical to be effectively agitated when the liquid chemical is mixed with the water, which can prevent an agitated liquid discharged from the water tank from including impurities, thereby preventing an obstruction phenomenon when a sprinkler and a high-pressure spray nozzle are used, which enables a filtering rod installed inside the water tank and configured to filter out impurities to be separated, thereby facilitating the maintenance and repair of the filtering rod, and which enables impurities accumulated inside the water tank to be effectively discharged along with a small amount of water, thereby enabling the clean state of the water tank to be maintained.

A gas and liquid-tight inlet connector to the inner chamber of a mufti-chamber pressure vessel is provided, comprising: a male gland extending through an orifice in the bottom of the flexible wall of the inner chamber and the lower wall of the rigid outer shell of the vessel, the male gland comprising an upper flange permanently, sealingly connected, with the lower surface of the flexible inner wall, so as to form a gas- and liquid-tight seal therewith, and a lower elongated member extending through the outer shell to be sealingly connected with a liquid inlet pipe, permitting liquid flow into the inner chamber, while maintaining the seal between the inner and outer chambers of the tank, thus maintaining pressurization in the outer chamber, as fluid enters the inner chamber, pushing the flexible wall upwardly into the outer chamber.
