My air conditioner drain is not only draining from the PVC outlet out side, it also is draining from the walls outside. Is this normal or do I have a problem? Solutions that I have tried: Liquid plummer

I will take a guess that the pvc is leaking inside the wall,either from a break or leaking joint.No more liquid plumber!This could be easy to fix or a nightmare.Would need to know more about wall material and how far the pipe goes from ac to outdoors.

If your air handler is in the attic, the sheetmetal catch plate (don't know the right name for it) that's under the coil may be leaking. You ought to get it checked out right away. If this is the case it could damage walls, ceiling, etc.
Hopefully, it's just a leaking pvc pipe that's not putting any water on the inside.

Two potential problems. First, and most likely, the drain tray (not the drain pipe)is probably clogged-up with gunk, preventing some of the water in the tray from reaching the drain hole. (The water pools in the tray instead of draining, until it overflows.) Drain trays under the evaporators very commonly fill up with all kinds of gunk (mold, dust, dirt...), even when you have a good air filter on the system. They should be routinely cleaned every few years along with the evaporator coil, but are often ignored until they rust out and even ruin the evaporator coil.

Second, the drain pipe might be a slow drain such that it allows some drain water to escape through it, but not enough so that the drainage tray overflows. It is very common because AC drains are slow drains that rarely get flushed out with a large volume of water, which helps prevent organic and inorganic build-up from forming. I had to use several applications of Drano foaming Pipe cleaner on my AC drain pipe recently, which eventually cleared out my AC drain that the previous owners had neglected for 30 years.

Liquid Plumber is probably the wrong product to use on an evaporator coil/drain tray, although I am not so sure it will cause more problems. The commercial cleaning solutions used to clean evaporator coils often contain muratic acid, which is a stronger, more caustic acid than the acid in Liquid Plumber. Using it a few times over the life of the coil to clean the coil should not ruin the coil or the drains. It is only when people use Liquid Plumber-type acids FREQUENTLY that people inadvertantly ruin their drain pipes.

Nonetheless, your problem on an A/C drain pipes is probably not a clog (for which Liquid Plumber or lye would be used) but a SLOW DRAIN due to build-up in the pipes, for which there are other, less caustic products designed to cling to build-up, remove it, and then harmlessly wash away (like the Drano foaming pipe cleaner).
