Drain hose flush system

An adapter comprising:

• a first connector having a proximal end to receive a volume of flushing fluid from a source of flushing fluid to flush an inside of a flexible hose;
• a second connector having a distal end including an outer diameter and pins extending from the outer diameter to demountably couple to the hose, the second connector to provide a fluid leak resistant connection between the hose and the adapter;
• wherein the first connector is coupled to the second connector to provide a flow of the volume of flushing fluid in a direction at an angle with respect to an axis of the hose, and the first connector further comprises a control to adjust the rotation of the flow of flushing fluid around the axis of the inside of the hose.

An adapter comprising:

• a first connector having a proximal end to couple to receive a volume of flushing fluid from a source of flushing fluid to flush an inside of a flexible hose;
• a second connector having a distal end including an outer diameter and pins extending from the outer diameter to demountably couple to the hose, the second connector to provide a fluid leak resistant connection between the hose and the adapter;
• wherein the first connector is rotationally adaptably coupled to the second connector to provide a flow of the volume of flushing fluid in a direction at an angle with respect to an axis of the hose, and to allow the first connector to rotate on an axis of its coupling with the second connector.

A hose flushing system comprising:

• a first connector coupled to a second connector and having a proximal end to form a demountable fluid leak resistant connection to receive a volume of a flushing fluid from a source of flushing fluid to provide a flow of the flushing fluid along an axis of a hose to flush an inside of the hose;
• the second connector having a distal end to form a demountable fluid leak resistant connection to the hose to provide the volume of the flushing fluid to the inside of the hose;
• wherein the hose flushing system is designed to be lifted and rotated with respect to the axis of the during the flushing, wherein the first connector further comprises a control valve to adjust a flow rate of the flushing fluid over a range between off and full flow and wherein the manipulating comprises adjusting the flow rate during the flushing.

A system comprising:

• means for demountably coupling and sealing an inlet proximal end of a conduit with one inlet and one outlet to a source of flushing fluid to flush an inside of a hose with a volume of fluid received at the inlet, the proximal end perpendicular to and having an opening coaxial with an axis of the outlet;
• means for demountably coupling and sealing the outlet to a distal end of the hose, the outlet including an outer diameter and pins extending from the outer diameter;
• means for providing a controlled flow rate over a range between zero flow and a flow equal to the volume of fluid received at the inlet along an axis of the inlet, the outlet, and the hose to flush the inside of the hose.
