When your drains are blocked, they encourage the growth of bacteria which causes diseases. This is because the waste and water flow back into the sink whenever a drain is blocked. With waste and water flowing back into your sink, you will be able to contact diseases and viruses. If you come in contact with this contaminated water, it may cause skin inflammation and irritation. To protect your health and that of your family, you should clean your drains.

Blocked drainage causes the foundation of your home to get soaked by water, thereby destroying its structure. In worst situations, it can cause your house to become flooded, destroying your walls and floors in the process.
