Sludge in the Pipes

So last night at 3:30 AM my alarm went off- I stumbled out of bed, eyes still blurry, and made my way over to the kitchen. I took a glance at the sink, couldn't see much, hmm- turned on the light and sure enough the sink was almost full, I had timed it perfectly..got to it just in time before the overflow...You see in the last 24 hours, we have had a clog. It seems that there had been a collection, a buildup, a stockpile of waste that had headed down the drain of despair and collected in our pipes. Yesterday, about 2PM, the buildup was complete...now the funny thing about living in an old Russian Apartment (or maybe just some ghetto apartments) is that the pipes for the drains all run together. (Luckily we were on the fourth floor- I can only imagine what would have happened if we were on floor one...) So I noticed the clog, in fact there was a pipe leak that caught my attention...and then I noticed the water wasn't going down the drain anymore... I called my co-worker, and he sent over the security guard. The security guard tied a plastic bag over the leaking pipe- good to go- and then unscrewed one of the pipes under the sink and sure enough an explosion of black sludge water shot out- alright- now at this point you would think that the pipes were unclogged, especially after seeing how much junk came out- but after he screwed the pipes back together, he turned on the water and it still seemed jammed- at this point he went back to work and came back about an hour later...now we will save the rest of the story for tomorrow- because it gets better, and I am not sure how it will turn out...:)
