Description of Work: Bathroom sink was not draining. Called the company and they were able to send someone that day. The plumber snaked and opened the drain, but no debris found. Same company had unclogged the same drain 10 months earlier. Plumber suggested that there may be something in the line catching hair since they unclogged the drain earlier and we have had problems in the past. He advised the only way to determine the true problem, a camera would have to be snaked through the line. He suggested I try a couple of DIY remedies that may keep the drain open and if they did not, then to call and they would use a camera to identify the problem and fix it.
