A waste tank clog removal system is provided for removing clogs during draining of a waste tank through a drain line. This system removes the clog by flushing the clog back into the waste tank. A bypass valve and a hose assembly are added to an existing waste tank drain and rinse system. The hose assembly is connected to the bypass valve and routed to the drain line, between a ball valve and a drain valve. When clogging occurs, the bypass valve is rotated to a bypass position, the drain valve is closed, and rinse fluid fills the drain line to push the clog back into the waste tank.

[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:] [1.] In a clog removal system including a waste tank, a drain line coupled to the waste tank, an outlet valve movable between a closed position and an open position, coupled to the drain line, a rinse fluid supply line coupled to the waste tank for supplying a rinse fluid, the improvement comprising:a bypass valve interposed in the rinse fluid supply line, said bypass valve movable between a rinse position that allows fluid to flow through the bypass valve to the waste tank for rinsing the tank such that the rinse fluid is then directed through an outlet of the tank through the drain line, and a bypass position that diverts rinse fluid from the rinse line to a bypass port; anda bypass line coupling the bypass port to the drain line to route the rinse fluid back through the drain line and into the tank when the bypass valve is in the bypass position; wherein during a clog at the outlet of the tank or in the drain line, the rinse fluid that is diverted through the bypass line forces rinse fluid back into the tank through the drain line thereby unclogging the system, and after said bypass valve is shutoff, the drain outlet valve is open for normal drain operation to allow the rinse fluid and waste to be drained through the drain outlet.
