What solid size must the integral screening of the pump vault prevent from passing?

The integral screening of the pump vault is designed to prevent the passage of solids that could potentially clog or damage the pump or the septic system. The specification for the size of solids that must not pass through this screening is typically set to 1/8 inch. By ensuring that particles larger than this size are effectively screened out, the system can maintain its operational efficiency and reduce the risk of failures related to solid waste accumulation.

The choice of 1/8 inch serves as a standard in many septic applications to accommodate the solid waste types that could enter the pump vault while allowing the effluent to flow properly. This helps maintain the overall health of the septic system and ensures that only appropriately processed materials flow through the system, minimizing maintenance needs and extending the lifespan of the equipment.
