Narrative
Benedum station pump p310 3/4 inch manual blow down gate valve was discovered to be leaking by to vent. The valve was not seating properly, allowing ngl to leak by through the system vent, as designed. The 3/4 inch valve is located on the pump skid and is used for manual blow down of station pump p310. The technician who discovered the leaking valve was able to get the valve to hold by working the valve and eventually getting it to seal off. The cause is unknown, however it is believed to be caused by trash from previous maintenance activity which may have lodged in the gate causing the valve not to seal off completely. Dcp ngl tech's will add station vent check after return to service from maintenance activity has been completed in the future.
