Back pressure is the same as absolute pressure. 3" water column of backpressure is the same as 1.5 psia, where atmospheric pressure is 30" wc and 15 psia. People sometimes say "backpressure" instead of just "pressure" because they don't want people to think the pressure is added on top of atmospheric pressure. Backpressure is the pressure added on top of a perfect vacuum.
