I've got a clog in my AC drain line, but the trouble that I'm having is that the drain line empties in an inaccessible location. It drops down through the wall and is connected via PVC pipe to the drain line of a bathroom sink.
I'm a bit reluctant to try to use a shop-vac to pull out the clog through the T in the drain-line, but is this my only other option?
I can send some pictures if those would aid in the description. Let me know, thanks!
