So I just looked out the window of my breakfast nook and noticed that my water level was about an inch below the waterline tile, just into the top of the plaster. After shouting a very loud expletive, I ran out to the equipment pad to find the pump running, straining to find water, and this lovely scene:
There is no breakage, all threads are intact. Anyone know what would cause the outlet pipe to blow out of the pump housing like this? I also noticed that the pipe going into the pump inlet is slightly loose. This stinks.
