I thought I would give this a try as my last resort before I placed a call to a plumber to take a look at my kitchen as the water has been draining slow for the last 2 weeks and you could also hear noises coming from the drain as if water was coming back up. Well to my surprise it seemed to have worked. I followed there instructions and used it for 3 nights and the drain is fine now. I am Very happy that I didn’t have to incur additional cost by having to call a plumber.
