Pro-Tip: To ensure long-lasting performance of the semi-trash pump, always flush the system with clean water after using the trailer for dust control on dirt lots. Sediment buildup inside the pump housing can wear down the impeller over time; a quick 2-minute rinse after your shift will keep your flow rate at the maximum 158 GPM for years to come.
