Why struggle with blocked drains when you can call the best plumber ever and get it all taken care of before you can say blocked drains? I remember one Saturday night a long time ago, when I was on my bathroom floor in water half covering my toes. I had been cleaning my bathtub and flushed the drain underneath it from residue and stuff. Suddenly it stopped and a hairball had lodged in a drain under floor. What to do on a Saturday night? Panic? No, I had worked with a plumber who had shown me this plug in the sewer, so I inserted the hose and flushed it all out!
