Why does one truck pump faster than another — even with a bigger CFM rating?
In this breakdown from the Michigan Septic Tank Association (MSTA) Conference, Mike Chouinard from National Vacuum Equipment dives into:
Solid column lifting vs air conveyance
Why atmospheric pressure is actually pushing product into your tank
How elevation limits your max vacuum
Why 20 inches of vacuum ≠ 24 inches
How air injection overcomes deep lift limitations
Why undersizing your pump is costing you time and money
If you're running long hose pulls, steep elevation changes, or deep tanks — this explains exactly why you’re hitting a wall.
We also cover:
✔ How a simple “stinger” setup can improve efficiency
✔ Why airflow (CFM) matters more than most operators think
✔ The safety risks of 90° elbows and rock blowback
✔ Real-world examples of 200+ ft pulls at elevation
If you build, operate, or spec vacuum trucks — this one matters.
