Abstract

A system and parts of a system that can be used to introduce fluid into a closed circuit. The system includes a valve having an inlet, an outlet, a flush inlet; a spool located in a valve body and coupled to a handle, and the spool can selectively, by the positioning of the handle, direct flow between the inlet, outlet, and flush inlet. The system also includes an uptake conduit comprising a valve connector that is configured to couple with the flush inlet, and a conduit, that is configured to allow fluid to flow therethrough. Additionally, the system has a system attachment having a system connector and a valve connector, and the uptake conduit and the system attachment are coupled to the valve.

Claims (19)

1. An apparatus comprising:

a valve comprising an inlet, an outlet, and an uptake inlet; a spool located in a valve body and coupled to a handle, and the spool is configured to selectively, by the positioning of the handle, direct flow between the inlet, the outlet, and the uptake inlet;

an uptake conduit comprising an uptake conduit valve connector, configured to couple with the uptake inlet, and a conduit, configured to allow fluid to flow therethrough; and

a circuit attachment comprising a circuit connector and a valve connector;

wherein the uptake conduit and the circuit attachment are coupled to the valve; the uptake conduit further comprises an entry apparatus comprising a conduit connection and a debris guard; the debris guard is configured to actuate between an open position and a closed position; and when the debris guard is in the closed position, the debris guard prevents debris larger than a certain size from entering into the conduit.

2. The apparatus of claim 1 , wherein the debris guard comprises a selector configured to selectively actuate the debris guard from the open position to the closed position.

3. The apparatus of claim 1 , wherein the debris guard comprises a filter configured to filter fluid entering the conduit.

4. The apparatus of claim 1 , wherein the conduit and the debris guard have a diameter that is less than 1.5 inches (3.81 centimeters).

5. The apparatus of claim 1 , wherein the conduit and the debris guard have a diameter that is less than 2 inches (5.08 centimeters).

6. The apparatus of claim 1 , wherein the debris guard is threaded.

7. The apparatus of claim 1 , wherein the uptake conduit is coupled to the valve by a quick connect.

8. The apparatus of claim 1 , wherein the circuit attachment is coupled to the valve by a quick connect.

9. The apparatus of claim 1 , further comprising a circuit and a pump; wherein the pump and the valve are within the circuit, and the valve is located before the pump on the circuit such that the pump draws from the valve.

10. The apparatus of claim 9 , wherein the circuit further comprises a circuit filter.

11. The apparatus of claim 9 , further comprising a vehicle and the circuit is a potable water circuit.

12. The apparatus of claim 9 , further comprising a vehicle and the circuit is a gray water circuit.

13. The apparatus of claim 9 , further comprising a vehicle and the circuit is a black water circuit.

14. The apparatus of claim 1 , wherein the valve is a three-way valve.

15. The apparatus of claim 1 , wherein the valve is able to prevent all fluid from passing therethrough.
