Narrative:

August 2011; A319 aircraft; yellow hydraulic system serviced twice in one day. Aircraft flew four flights. Overnight check performed in ZZZ. Aircraft flew three more flights after overnight check. Before departing ZZZ1 for the fourth flight; pilot requested yellow system fluid service. Aircraft replaced due to write-up in ZZZ1 before departure and sent to hanger for repair; removed/replaced (right/right) # 2 engine hydraulic pump.is it a maintenance procedure to just replenish hydraulic fluid? Should maintenance be looking deeper into the cause of the hydraulic fluid depletion? Past experience of a leaking yellow system hydraulic pump: hydraulics fluid settles in the inside of # 2 engine cowl. When reverse thrust is selected; the fluid can be sprayed on left side of aircraft between the engine and fuselage (landing gear). Suggest stop rushing pilots and maintenance must pay attention to detail.

Title: Captain raises concerns about his company's maintenance practice of continually servicing a Yellow Hydraulic System on an A319 aircraft; rather than troubleshooting the cause of the fluid loss.
