It's possible it connects into a normal drain line somewhere downstream. Mine drains into the same pipe as the sinks in the master bathroom. I bought a snake (drain pipe auger) at Home Depot for ten bucks or so. Fortunately, only the sinks were clogged/slow - not the shower or toilet.G26ster wrote:I believe last time the plumber blew the line out from the closet end. However, in viewing videos online, there is supposed to be an outside pipe that you can suction to clear the line. Trouble is there are no pipes out by my compressor or any I have seen in the 15 years I have lived here. Is it possible it just connects to the main sewer line under the slab?
Good luck. That a/c sludge is some nasty stuff.
