Despite the regular maintenance of your bathrooms, bad odors persist? It’s definitely coming from the pipes. Do not lose hope, many solutions exist to eliminate them. The first thing to do is to clean your siphon thoroughly. This is often the cause of foul odors. Place a basin under your sink, put on gloves and unscrew the siphon. Let the water flow into the basin and remove any dirt by hand. Clean the siphon with White vinegar and screw it back. Run some water to check for leaks.
