2001 Chevy Silverado Leaking Fluid

My 2001 Chevy Silverado recently began leaking what appears to be a clear odorless liquid. It seems like water to me. It is coming off of a pipe right beside my front passenger side tire. It is connected to what kind of looks like a muffler and says FLOW on it. Anybody have an idea what's going on? heater control valve Does it leak when the air conditioner is turned off? If not, it is condensation from the a/c system and it is a normal condition.
