Interceptors ( clarifiers) (including grease, oil, sand, solid interceptors, etc.) What's important to remember about AAVs is that they only allow for the relief of negative pressure in the drainage system. Once the grease interceptor reaches maximum capacity, a certified grease trap cleaning company will need to be called in order to service the grease interceptor. As the waste stream flows through the orifice in the flow control device negative pressure is created, drawing in air from the air intake which is intended to mix with the waste water as it enters the grease interceptor aiding in separation efficiency.
