How to Clear a Blocked Kitchen Drain Outside

An outdoor kitchen drain is crucial to your home's plumbing system. It helps to flush wastewater from your kitchen sink and other appliances on the ground floor to the lateral drains in the road. If your outdoor kitchen drain becomes blocked, it can cause significant issues, including slow draining, water pooling, and unpleasant odours. Understanding how to clear a clogged kitchen drain outside is essential to maintaining your home's plumbing health.
