SINK DRAIN WATER COLLECTOR
Improvements in conservation and collection of water that gray water that normally is washed down a drain is disclosed. The conservation tool is a side pipe or “T” that allows water with minimal or no heavy solids to flow out the side pipe. The side pipe exists above a water trap at a height that is about the top of the trap. Heavy materials will fall straight down the trap but only fairly clear fluids will stay above the trap and flow down the side pipe. The side pipe is connected with a hose to a reservoir holding tank. A valve is manually operable to stop any flow into the reservoir. The reservoir is removable for use to feed plants or grass with the collected gray water.
This application claims the benefit of Provisional 61/253,729 filed Oct. 21, 2009 the entire contents of which is hereby expressly incorporated by reference herein.

2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 1.98
A number of patents have been issued that provide sinks, collection vessels, valves and collapsible bottles. Exemplary examples of patents that have been issued that address some of these components are identified and discussed below. While various pieces are shown, none of them show or describe collecting only the relatively clean a portion flow down a drain.
U.S. Pat. No. 5,165,456 issued Nov. 24, 1992 to Richard F. Woolman discloses a Diverter Apparatus and method For Saving Fresh Water. This method involves diverting water from a faucet or shower while hot water is filling the line. The water that is being collected is pure drinking water. The conservation is not water that would be undrinkable. While this patent discloses the collection of water that would normally be washed down the drain, the water being collected has no contaminations and is being collected at the supply as opposed to the drain line of a sink. The present application can be used with this patent to provide additional water savings and conservation.
U.S. Pat. No. 3,750,196 issued Aug. 7, 1973 to Donald William Halferty and U.S. Pat. No. 7,401,286 issued October 28, 2008 to Alice Lenora Parker both disclose Waste Water Holding Systems where all of the water from a drain is collected for later disposal. While these products collect all of the water, the collection is for temporary holding within a container, and due to the solids that are collected within the container the collected fluid is later disposed of or otherwise discarded without conservation.
U.S. Pat. No. 4,268,392 issued May 19, 1981 to John Hayes discloses a Disposable Plastic Trap Bag. The trap bag again collects all of the fluid that drains from a sink. The predominant item that is collected within the bag is solids or semi-solids that are heavier than water. The solid material collects in the bottom of the bag and the bag is simply removed from the holding bucket for later disposal. While this patent discloses a holding bag, the collected material is not usable for watering or other uses, and mostly contains heavier that water materials.
U.S. Pat. No. 3,083,877 issued Apr. 2, 1963 to W. K. Gash, U.S. Pat. No. 3,939,887 issued Feb. 24, 1976 to Thomas J. Scarnato and U.S. Pat. No. 5,310,068 discloses collapsible containers. These collapsible containers are for changing the amount of material or fluid that can be held within the container. While these patents are adjustable to change the amount of volume that is held within the containers, these containers are not intended to change their size (not volume) to match the drain height from a drain and they further lack handles for easy transportation or a check valve to prevent an overflow condition.
U.S. Pat. No. 4,197,597 issued Apr. 15, 1980 to Ed P. Tomes discloses a Water Recycling with Solids and Foam Removal. While this patent discloses a collection reservoir, the collection is to separate solids and foam from water that is sent down a drain. Any conservation of water is also washed down the drain. This patent is mostly for conservation of the sewage from a house and there is little or no conservation of the water.
What is needed is a collection reservoir that can be installed under most sinks to collect gray water that can later be used to water plants and the like. The proposed application provides this solution with a simple device that simply requires a change to the drain pipe of house, condo or apartment. The change to the drain pipe allows for only fairly clear water to be collect while solids or semi-solids are washed down the drain.
BRIEF SUMMARY OF THE INVENTIONIt is an object of the sink drain water collector to collect relatively clean gray water that would normally be washed down the drain of a sink. Typically the water that is useful for watering plants or for other purposes that does not require the same level of purity often remains above the heavier water that contains contamination and heavier solids. One of the main goals of this water collector is to separate the relatively clean water while letting more contaminated water wash down a drain.
It is an object of the sink drain water collector for the water collector to be relatively simple in construction and installation. The separation of gray water is from the replacement of a sink drain pipe with a similar sink drain pipe having a side T that is connected to a flex drain hose. The location of the side pipe or T is about the same height as the drain line located after the P trap or elbow. This location is ideal for allowing mostly clean and clear gray water to be collected.
It is another object of the sink drain water collector to have a removable storage tank or reservoir. The reservoir is connected to the flexible drain hose. The reservoir allows for both the collection and delivery of the water to plants. Based upon the user preference the volume of the reservoir can be adjustable to change the amount of water that is collected as also the weight of the reservoir that the user can carry to water plants. The height or volume of the reservoir is also adjustable to reduce back washing fluid out of the reservoir.
It is still another object of the sink drain water collector to include a fill shut off valve to eliminate the potential of the reservoir being over filled and pouring excessive amounts of gray water under a cabinet. The shut off valve can also be closed with a user removes the reservoir for watering plants. This allows the sink to still be used when the reservoir is removed.
Various objects, features, aspects, and advantages of the present invention will become more apparent from the following detailed description of preferred embodiments of the invention, along with the accompanying drawings in which like numerals represent like components.
Water that would normally flow down the down pipe 11 would pass below the dip 12 and through the trough 13, through the back elbow 15 where the trap is coupled, with a coupling nut 16, to an elbow having a crown 17 and a drain pipe 18 that connects to the sewer or other drains. The threads of a side connection 20, are located is the side of the down pipe for connection with a side pipe or “T”.
The threads 34 of a fitting 33 that has saw toothed edged are threaded into the side of the down pipe 11. A first end 31 of a flexible pipe 30 is secured onto the saw toothed edges of the fitting 33. The saw toothed edged both grip the flexible pipe 30 and seal the flexile pipe 30 to prevent leakage. While saw toothed edges are shown and described in one or more locations in this preferred embodiment other common methods of connecting a flexible or rigid pipes or hoses together are contemplated. The fitting or side connection 33 can have a variable size opening where the opening size is adjustable by altering the side of the flow though hole or orifice. Changing the size of the flow through orifice will also change the height of the water level that is required for water to flow into the flexible tube or pipe 30.
The second end 32 of the flexible pipe 30 is secured to the saw toothed fitting 43 on a water reservoir or tank 50. The tank or reservoir 50 collects gray water that drains from above the trap, through the flexible hose 30 and into the fitting 43. In the preferred embodiment, the tank or reservoir 50 has a handle 41 for easier transportation of the tank or reservoir 50. While a particular handle 41 is shown and described the configuration and existence of the handle is variable. In the preferred embodiment, the reservoir 50 is configured with accordion or expandable pleat 42 type side walls to allow the height size and volume of the reservoir to be adjusted. The adjustment also allows the location of the fitting 43 to be adjustable to reduce the possibility that any collected gray water from back washing into the side pipe or “T” connection 20. A cap or lid 40 allows fluid that flows through the flexible hose 30 to enter the tank or reservoir 50.
The head 70 has the saw tooth fitting 43 where the flexible tube is connected (as shown in
A lower cap 80 closes the bottom of the lower portion with a ball float 76 that prevents overfilling of the reservoir. When the water level of within the reservoir get too high the water level will lift the ball float 76 within the lower cap 80 and block flow through the lower portion 49 and into the reservoir through the opening 82 in the lower cap 80. A pair of ears 81 on the lower cap 80 allows an operator to tighten or loosen the lower cap 80 on the lower portion 49. The lower cap 80 has a top opening 84 that is secured onto the lower portion 49. Gray water can flow through the top opening 84 and out the bottom opening 85 as long as the flow is not being blocked by the ball float 76. When the cap 40 is removed the float ball 76 will seat in opening 85 (
