Description
- 1. Field of the Invention
- The present invention relates generally to a fresh water flushing device for use with a toilet located in a limited space environment and, more particularly, to a fresh water flushing device for a marine sanitation device (MSD) located on a boat which can be remotely mounted in a remote position. The fresh water flushing device may be used as an aftermarket add-on or a value-added accessory that reduces the cost of MSDs having an attached tank.
- 2. Description of Related Art
- Disposal of biological waste poses a unique challenge in the boating industry, not only in terms of the waste disposal itself, but also in terms of space restriction, water supply, odor control and overboard discharge laws. Toilets on boating vessels are typically called marine sanitation devices, or MSDs, which process, store and dispose of the waste products. This disposal can be achieved through the use of environmentally-compatible chemicals to break down the waste before storage or discharge. If discharged, the waste cannot have any visible floating solids and must meet bacterial health safety regulations.
- Whether the craft is docked or not, an MSD requires a sufficient supply of water to operate effectively. In larger vessels having more space, installed, onboard fresh water tankage provides the source of fresh water for MSD use. In smaller vessels, sufficient space is typically not available to allow for an integral fresh water tank to supply the MSD. Accordingly, the toilet is typically fed by seawater via a through-hull raw or seawater inlet and hose, a series of pumps, valves and hosing. Whether docked or moving, these smaller vessel MSDs can be fed by raw water. As a result of this raw water feed, odor can result from minute marine organisms (plant and animal) that die and decompose in the system. The boating industry is replete with information and tips for containing and/or controlling this odor. Some of these techniques include chemical treatment, live aerobic bacterial treatment, constant monitoring including routine replacement of hoses and valves, installation of specialized odor blocking valves and strainers on the intake line and frequent flushing. All of these techniques have drawbacks and/or disadvantages in terms of product costs, maintenance and cleaning of the additional components, and wear/tear and degradation of soft (rubber) components.
- There is a need in the art for an economically feasible, minimally intrusive, non-pressurized fresh water flushing device for use with MSDs to control and/or eliminate odors associated with raw or seawater supplied systems. There is a further need in the art for a non-pressurized fresh water flushing device that can be used as an aftermarket add-on that can be retrofitted to an existing raw water supplied system or that can be used as a value-added accessory that can reduce the cost of MSDs having an integral tank.

According to a second aspect, the invention comprises an economically feasible method of retrofitting an existing MSD with a non-pressurized fresh water flushing system. According to a third aspect, the invention comprises an easy-to-install kit for providing a non-pressurized fresh water supply system to new and/or existing MSDs. According to a fourth aspect, the invention comprises a fresh water supply flushing system for a toilet located within a vessel having limited space.
- In accordance with the first aspect of the present invention, a non-pressurized fresh water supply flushing system for an MSD is provided. The flushing system includes a fresh water reservoir having a predetermined capacity for holding a predetermined volume of fresh water, a mounting arrangement for mounting the fresh water reservoir to a support surface, a fresh water source associated with the fresh water reservoir for supplying fresh water to this fresh water reservoir and a fluid connection fitting for transferring the predetermined volume of non-pressurized fresh water from the fresh water reservoir to the MSD upon activation of the MSD.
- In accordance with the second aspect of the invention, a method of retrofitting a MSD with a fresh water supply flushing system is provided. The method includes providing a fresh water reservoir having a predetermined capacity for holding a predetermined volume of fresh water, mounting the fresh water reservoir to a support surface at a predetermined location with respect to the marine sanitation device, connecting the fresh water reservoir to a fresh water source and providing a fluid connection fitting for connecting the fresh water reservoir to the MSD for transferring a predetermined volume of non-pressurized fresh water from the fresh water reservoir to the MSD upon activation of the marine sanitation device.
- In accordance with the third aspect of the present invention, a kit for installing a fresh water supply flushing system with a MSD is provided. The kit includes a fresh water reservoir having a top portion and a bottom portion. The fresh water reservoir has a predetermined capacity for holding a predetermined volume of fresh water. The kit also includes a mounting arrangement for mounting the fresh water reservoir to a support surface. The fresh water reservoir has a fresh water in-feed fitting positioned through a bottom portion of the fresh water reservoir for supplying a continuous supply of fresh water into the fresh water reservoir. A float control valve is located within the fresh water reservoir to control the predetermined volume of fresh water supplied through the fresh water in-feed fitting into the fresh water reservoir. A fluid connection fitting is located at the bottom portion of the fresh water reservoir for transferring the predetermined volume of fresh water from the fresh water reservoir to the MSD through a gravity feed upon activation of the MSD.

a mounting arrangement for mounting said fresh water reservoir to a support surface;
a fresh water source associated with said fresh water reservoir for supplying fresh water to said fresh water reservoir; and
a fluid connection fitting for transferring said predetermined volume of fresh water from said fresh water reservoir to said toilet upon activation of said toilet.
19. The fresh water supply flushing system of claim 18 , wherein said support surface is located above said marine sanitation device and said fresh water reservoir is mounted in a vertical position to enable non-pressurized gravity feed of said predetermined volume of fresh water from said fresh water reservoir through said fluid connection fitting to said marine sanitation device and said flushing system includes a fluid in-feed line connected below said fresh water reservoir for supplying a continuous source of said fresh water to said fresh water reservoir.
20. The fresh water supply flushing system of claim 18 wherein said vessel is one of a camper, a train, a trailer, a bus and a boat.
