The damaged pipe may not have leaked before because it was not full of water. I do not think fixing the pipe caused your problem. My thought is there is a blockage below that point. There should be a vent out the roof that vents positive pressure. If there is a blockage and the pipe is filling with water it may not vent properly.

The pore pressure in soil is divided into two categories as follows, 1) negative pore pressure and 2) positive pore pressure. The zone of soil that is below water table will be fully saturated. The pressure in the pore is greater than atmospheric pressure. Hence, it is said to be positive pore pressure.

The result is the pressure of the air pushing from the outside of the can is great enough to crush it. The sudden collapsing of an object toward its center is called an implosion. Nature wants things to be in a state of equilibrium or balance. To make the internal pressure of the can balance with the external pressure on the can, the can implodes.
