Clogged Sink

For the past couple of weeks my bathroom sink has been draining slow...I thought it was the massive amounts of hair that I loose on a daily basis. I tried to take care of the issue by myself but the Drano I poured in ended up coming out the pipes in the back, running all over the bathroom floor and leaving me with a bleached out rug and bath towels that I used to clean up the mess. It was time to call in an expert (and by expert, I mean Tim my handy brother in law). He had to fix a seal and unhook the pipe where it connects to the wall to pull out TWO CAPS (one was a tooth paste cap and the other was a larger cap). Seriously, how do these things get down there?!?! They must have been there when we bought the house because I haven't lost anything. I'm so happy to have my bathroom sink back! Thanks Tim!
