There is provided a drip emitter for providing low flow irrigation. The drip emitter includes a mixing chamber system to maintain flow of debris with the fluid flowing through the emitter. The chamber system includes an inner and outer chamber. Both chambers receiving reduced pressure fluid compared to the conduit providing the fluid for the drip emitter. The outer chamber is supplied with greater reduced pressure fluid as compared to the fluid supplied to the inner chamber. A first check valve controls discharge of fluid for irrigation, and a second check valve controls the flow between the first and second chambers. The first and second chambers expand and contract in response to the operation of the check valves to provide the mixing of the debris with the fluid flowing through the emitter.
