I am having a bucket (every two days) full of water coming from my furnace. The water is strictly coming from the side plastic pipe, which I have been calling the condesation pipe. Is this a problem that I have to get looked at? My furnace is a gas high efficiency --- about 12 years old.
I would appreciate any input

Thanks

Yes your drain is stopped up and after 12 years that furnace needs to be serviced by a professional for your safety.
