Vehicle wastewater drainage system
View Patent ↗A wastewater drainage system for a vehicle, such as a recreational vehicle (RV), is provided. The system includes a pump, such as a macerator pump, in selective fluid communication with the black water tank and the gray water tank, and a drainage hose connected to the exit end of the pump for directing wastewater to a wastewater storage area. The system allows the RV user to clean the black water tank using water from the gray water tank, and allows gray water to be stored in the black water tank so that less time is spent draining the tanks and more time is spent enjoying the RV experience.
1. A wastewater disposal system for a vehicle, comprising:
a black water tank;
a gray water tank;
a discharge pipe in selective fluid communication with the black water tank and the gray water tank;
a pump having an outlet;
an outlet hose connected to the pump at one end and having an exit at an other end; and
a bypass hose releasably connected to the discharge pipe and to the outlet hose, the bypass hose coupled to the discharge pipe and the outlet hose for selective fluid communication therebetween.
2. The wastewater disposal system according to claim 1 , wherein the bypass hose includes a valve positioned at each end thereof for selecting a desired flow rate through the bypass hose.
3. The wastewater disposal system according to claim 1 , wherein the pump further includes an inlet attached to the discharge pipe in fluid communication therewith and permanently attached to the discharge pipe of the vehicle.
4. The wastewater disposal system according to claim 1 , wherein the system includes an inlet hose that communicates between the discharge pipe and the pump.
5. A wastewater disposal system for a vehicle including a black water tank, a gray water tank, and a discharge pipe in selective fluid communication with the black water tank and he gray water tank, the wastewater disposal system comprising:
a pump having an inlet and an outlet, the inlet of the pump attachable to the discharge pipe for fluid communication therewith;
an outlet hose connected to the pump at one end and having an exit at an other end; and
a flush hose connected to the outlet hose and connectable to the black water tank for selective fluid communication therebetween for directing wastewater from the outlet hose to the black water tank.
6. A wastewater disposal system for a vehicle, comprising:
a pump having an inlet and an outlet;
an outlet hose connected to the outlet of the pump at one end and having an exit at an other end; and
a discharge device attached to the exit of the outlet hose, said discharge device including an adapter for releasably securing the discharge device to an opening defined by a wastewater storage area, said opening having a diameter greater than that of said outlet hose;
wherein the discharge device comprises a valve for selecting a desired flow rate therethrough.
7. The wastewater disposal system according to claim 6 , further comprising an inlet hose for directing a flow of wastewater from a discharge pipe of the vehicle.
8. The wastewater disposal system according to claim 6 , wherein the adapter is capable of preventing release of gases from the discharge device to atmosphere.
9. The wastewater disposal system according to claim 6 , wherein the pump is a macerator pump.
10. The wastewater disposal system according to claim 7 , wherein the inlet of the pump is attached to the inlet hose and in fluid communication therewith.
11. A wastewater disposal system for a vehicle, comprising:
a pump having an inlet and an outlet;
an outlet hose connected to the outlet of the pump at one end and having an exit at an other end; and
a discharge device attached to the exit of the outlet hose, said discharge device including an adapter for releasably securing the discharge device to an opening defined by a wastewater storage area, said opening having a diameter greater than that of said outlet hose;
wherein the adapter is capable of preventing release of gases from the discharge device to atmosphere.
12. The wastewater disposal system according to claim 11 , further comprising an inlet hose for directing a flow of wastewater from a discharge pipe of the vehicle.
13. The wastewater disposal system according to claim 12 , wherein the inlet of the pump is attached to the inlet hose and in fluid communication therewith.
