Water Leak from Bathroom Ceiling, Second Time in 4+ Years

At around 4 pm today, I noticed dripping sounds somewhere and I thought some work was going on at the swimming pool of the next condo which faces this unit. Then I felt the sounds were coming from some place much nearer. I found the bathroom ceiling was leaking in a big way. Again! This happened a few years ago and the water heater had to be replaced then. I immediately contacted the owner and agent and the plumber the agent arranged came within two hours. He said, “heater spoiled.” Oh no. Believing he is an honest guy, it means the heater lasted only for less than 4 years! The man will come again tomorrow, bringing his cutter to make an opening to the ceiling and a new heater.
