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.
