The answer to 'drain cleaning overflowing' is that a clogged or backed-up drain is the most common cause. This can happen due to accumulated hair, soap scum, food particles, or other debris building up over time. Symptoms include water pooling or slow draining in sinks, tubs, or showers, and in severe cases, the drain may overflow.
For minor clogs, you can try DIY drain cleaning methods like using a plunger, drain snake, or chemical drain cleaner. However, if the clog is severe or the problem persists, it's best to call a professional plumber. They have the right tools and expertise to properly diagnose and resolve the issue, preventing further damage or flooding.
