I need to re-route my AC condensate line. The installer has it coming out of the side of my house (at attic height) which I agreed to, but it puts out so much water that my patio is very wet.

I'm going to re-route this to under the house and exiting out of a lower vent. The run is about 65' and I need to determine the amount of slope.

Any suggestions as to the amount of slope I should be doing for this 65' long PVC pipe? I'm also going to look for another exit and possibly shorten the run. I may also be able to plumb this into a sewer vent, but my neighbor is telling me not to do this.

Thanks
