The Day the Kitchen Drain Backed Up
It was a busy Friday night at a local restaurant. The kitchen was buzzing with activity—orders flying in, dishes piling up, and the sink working overtime. Suddenly, the drain slowed to a crawl, and within minutes, murky water began pooling around the floor. The staff scrambled to manage the mess, but the damage was done: service slowed, customers grew impatient, and the restaurant lost valuable business.
This scenario is all too common, and it’s not just limited to restaurants. Clogged drains can wreak havoc in homes, commercial buildings, and industrial spaces alike. For contractors, understanding the root causes of clogs and how to prevent them is essential to maintaining smooth operations and happy clients.
Let’s break down the top causes of clogged drains and actionable steps to keep them clear.
Top Causes of Clogged Drains

- Grease and Fat Buildup
In kitchens, especially in restaurants, grease and fat are the biggest culprits. When washed down the drain, they cool and solidify, sticking to pipe walls and trapping other debris. Over time, this creates a stubborn blockage. - Food Waste
Even with garbage disposals, food particles like coffee grounds, eggshells, and starchy foods (e.g., pasta and rice) can accumulate in pipes, leading to clogs. - Hair and Soap Scum
In bathrooms, hair combines with soap scum to form dense clogs that can slow or stop drainage. This is a common issue in both residential and commercial settings. - Mineral Deposits
Hard water leaves behind mineral deposits that narrow pipes over time, reducing water flow and increasing the risk of clogs. - Foreign Objects
Items like wipes, paper towels, and sanitary products are often flushed down toilets, causing blockages in sewer lines. Even products labeled “flushable” can cause problems. - Tree Roots
For outdoor plumbing, tree roots can infiltrate pipes, cracking them and causing major blockages. This is a particular concern for older properties.
How to Prevent Clogged Drains
- Install Drain Screens
Use screens in sinks and showers to catch hair, food particles, and other debris before they enter the pipes. - Dispose of Grease Properly
Instead of pouring grease down the drain, collect it in a container and dispose of it in the trash. This simple step can prevent major blockages. - Regular Maintenance
Schedule routine drain cleaning to remove buildup before it becomes a problem. For commercial properties, this is especially important due to higher usage. - Educate Staff and Clients
In restaurants and other commercial spaces, train staff on what can and cannot go down the drain. For residential clients, provide clear guidelines to prevent misuse. - Use Enzyme Cleaners
Enzyme-based drain cleaners break down organic material like grease and food waste without damaging pipes. Use them monthly to maintain clear drains. - Inspect Outdoor Plumbing
For properties with outdoor plumbing, regular inspections can help identify and address tree root intrusion early.
