Clogged drains are a common plumbing problem, especially in kitchens and bathrooms. They are often caused by a buildup of grease, hair, soap scum, or other debris. To prevent clogs, avoid putting grease or food scraps down the drain, and use a drain strainer to catch hair and other debris. To clear a minor clog, you can try using a plunger or drain unclogging solution from your local supermarket. If the clog persists, it’s best to call a professional plumber to avoid causing further damage to your pipes.
