Septic Tank Pump Out 001

This is my first pump out with the new truck. It done well had a few kinks with speed of pumping. I believe i have corrected it once I returned home. Had to disassemble some relief valves. Also had to reseal the large top manway. In the beginning of the video you can hear the "Hissing" from above.
