I have a drainage pipe (PVC - looks like the air unit/water heater one) of some sort that is in my garage it doesn't belong to the water heater or the air unit I know where those are. I cannot think of anything else it would belong to.. it looks like it goes into my kitchen.. this morning it created a puddle in the garage but it has never done this before.

  • I assume your kitchen is behind that wall where the pipe exists? What's above your garage? Is it an attic?

Is that 3/4 inch PVC? If so then it's very likely a backup drain line for a furnace and/or evaporator coil (A/C). It might be dumping on your garage floor on purpose to warn you that the main drain line is clogged. I would expect it to drip whenever your A/C is turned on.
