Also known as a drain auger, a drain snake is a coiled device around ¼-inch thick. To use a drain snake, put the end into the entrance of the drain. Turn the handle to force the snake deeper, using extra pressure to force it through the bend in the pipe. Keep turning until the snake hits the clog, then either pull the snake and remove the obstruction or force it through. Once the snake is out of the drain, run the water on full blast for a few minutes to ensure the obstruction is completely removed.
Sometimes a faucet leak can be stopped by replacing the rubber washer at the end of a faucet stem or cartridge. This is a more common repair on older fixtures when things were built to last and designed to be able to be maintained. Other times the whole stem or cartridge needs replacement or the bibb seat deeper back into the fixture needs replacement. That leads to matching up the right components and often times making a trip to the hardware store or plumbing supply house necessary due to the many varieties, makes and models of faucets. My advice is to make sure your Plumber has faucet repair kit on their truck before having them come out to assess the issue.
