    Water pouring from outside pipe

    I am in a 2 story condo in FL built 4 years ago, and my neighbor has been mentioning to me for some time that water is coming from the drainage pipe outside near the A/C. I ignored her because I thought she was talking about the dripping it's supposed to do as it gets rid of the condensation.

    I just got my water bill, though, and it's up by nearly $30. Upon looking at the pipe, one (not both) of the drainage pipes has a steady stream of water coming out... definitely not drips, and whether the ac is running or not.

    I checked the air handler on the 2nd floor, and there is no evidence of a leak up there that I can see, and there is a float switch which has not tripped.

    I've blown out the line before with compressed air in a previous house, but if it were clogged with algae, my understanding is that the second line would be leaking and/or the float switch would have tripped, right? It's been a few years since dealing with a/c issues.

    Am I correct in now assuming that there must be an actual leak somewhere to cause a steady stream as opposed to simply wicking of the condensation?

    Could it be in the attic somewhere? I knew a lot more about the a/c system in my last house as I was there when it was installed and bought the installers lunch so I could ask a few questions. Not so much about this one.

    Sounds like it isn't an HVAC issue. I would suggest calling a professional just in case.

    I've seen a AC condensate line joined to a Hot Water safety valve drain to the outside.

    Just a thought but feel the pipe coming out of your hot water heater TP Safety valve, some call it a pop off valve. If it is warm then either your temp setting on the water heater is too high, house pressure too high or you have a faulty safety valve.

    Like I said... just thinking out loud.

    The drain pipe could go to a pan under your water heater or washer. Or, it could go to the relief valve on the water heater. Check those areas.
