The earthy smell in the kitchen drain and the gurgling in the bathroom drain could be caused by a buildup of organic matter and debris in the pipes. When food particles and other organic material get trapped in the kitchen drain, they can decompose and produce a musty, earthy smell. Additionally, the buildup of material in the pipes can cause blockages and lead to air bubbles getting trapped, which can result in gurgling sounds in the bathroom drain. Regular cleaning and maintenance of the drains can help prevent these issues. **
