Is there any reason why I should not plumb my drain for my a/c unit into the drain for a bathroom sink that will be no more than a few feet away. I would much prefer this over running another set of PVC outside, only to have a very soggy portion of lawn right out of my back door. We live in louisiana, and it gets hot here, and very humid. A/C units here can fill up a couple 5 gallon buckets a day. Why couldnt all that go into the septic system instead of my lawn?
