B767 300ER Avionics Bay
I am a SCCM working on the above a/c, during a recent flight, the forward toilet would not stop flushing. I followed the guidelines that we have as cabin crew and pulled the T bar under the toilet, this worked to start with, then the water started to pour continuously, there seemed no way to stop it, the flight crew were concerned as I was, that the water would enter the avionics bay. A PAN call was made and a diversion was planned. As the water was now pouring down the a/c and pax were now aware, I pulled the toilet shroud off and finding the shut off lever, stopped the water. The flight continued to its destination.
I respectfully ask if any engineer or pilot could tell me the consequences of a large amount of water getting into the avionics bay, I am aware there is a seal round the hatch, but this particular B767 is circa 1993. I would also ask if there is any kind of fire suppression system in the bay.
I want to make clear that I have the upmost respect for my flight crew and the airline I operate for, I merely want to put my mind at rest.
