For a 3 meters level variation (may go up to 5 meters) what type of sensor you recommend? This is another requirement.I would conclude that there is no definite correlation between the three series of data, within the limits of measurement accuracy.
I speculate that the apparently consistent drop in the water pressure sensor readings might be due to some gradual 'settling-in' process, e.g. a permanent slight deformation of some part of the sensor. Repeating the measurements, over a longer time period, might help to prove/disprove that theory.
