Positive means the right column is higher, so.

The left side has the higher pressure.
The differential equation assumes equal-elevation taps, the same line fluid above both interfaces, negligible capillary effects, and hydrostatic equilibrium. More general arrangements require walking pressure continuously through every fluid column.
