Polylok’s Orifice Diffuser ensures even distribution on lateral piping from all orifices in any system by separating the discharge orifice from the drain media; which effectively protects the system. Because of the low pressure in most wastewater systems, typically 1-3 psi, it is extremely important to ensure drainage media does not interfere with the discharge orifices. Systems should be designed with the use of an orifice diffuser on all discharge holes to ensure even distribution and even system pressure after back-filling.

Small Orifice Diffuser is also available – 3081. See the installation link for specs on this.
