Top Causes of Drain Blockages in Commercial Properties

 Commercial properties, such as restaurants, office buildings, and retail stores, often face unique challenges when it comes to maintaining their plumbing systems. Drain blockages can lead to significant disruptions in operations, resulting in costly repairs, safety hazards, and even temporary business closures. Understanding the most common causes of drain blockages in commercial properties can help business owners and facility managers take preventative measures to avoid these issues.

In this blog post, we'll explore the top causes of drain blockages in commercial properties and provide tips on how to keep your plumbing system functioning smoothly.

9 Common Causes of Drain Blockages in Commercial Properties

1. Grease Buildup

One of the leading causes of drain blockages in commercial kitchens, especially in restaurants, is grease buildup. When fats, oils, and grease (commonly referred to as FOG) are poured down the drain, they may initially seem to flow easily with water. However, over time, these substances cool and solidify in the pipes, leading to significant blockages.

Grease traps are essential for restaurants and commercial kitchens to capture FOG before it enters the drainage system. However, if not cleaned regularly, even grease traps can overflow, causing blockages further down the line.

Tip: Install and maintain grease traps, and ensure kitchen staff is trained to dispose of grease properly to avoid unnecessary drain clogs.

2. Food Waste

In commercial kitchens, food waste is another common cause of drain blockages. Leftover food, peels, and debris can easily enter the drains, either during dishwashing or through floor drains, leading to clogs. Many businesses rely on garbage disposals to break down food waste, but even these systems can become overwhelmed, causing blockages.

For retail stores, food courts, and other areas where food is prepared or served, it's crucial to properly manage food waste disposal to avoid plumbing issues.

Tip: Encourage staff to scrape plates into the trash before washing them and use strainers in sinks to catch food particles.

3. Foreign Objects

Foreign objects such as paper towels, sanitary products, and packaging materials can accidentally find their way into drains, particularly in commercial bathrooms and restrooms. These items are not designed to dissolve in water and can quickly create serious blockages.

In office buildings, retail environments, and other high-traffic commercial spaces, improper disposal of foreign objects in toilets and sinks can lead to frequent blockages and even damage to plumbing systems.

Tip: Place clear signage in restrooms and kitchen areas reminding staff and visitors to dispose of non-flushable items in the trash, not in the sink or toilet.

4. Soap Scum and Mineral Deposits

In commercial properties with high water usage, such as gyms, hotels, and office buildings, soap scum and mineral deposits can accumulate over time. Hard water contains minerals like calcium and magnesium, which can cling to the inside of pipes and create blockages. When combined with soap, these minerals can form a sticky residue that narrows the pipe diameter, slowing drainage and causing clogs.

Tip: Regularly descale pipes and install water softeners in properties where hard water is prevalent to reduce mineral buildup.

5. Hair and Other Debris

Hair is a common cause of drain blockages in commercial properties with high foot traffic, such as salons, hotels, and fitness centers. Hair can easily get trapped in drain pipes, forming clumps that restrict water flow. Other debris, such as dirt, lint, and dust, can accumulate over time in floor drains, causing further blockages.

Tip: Install drain covers in showers and floor drains to catch hair and debris before they enter the plumbing system.

6. Tree Roots Infiltration

Tree roots are a surprising but significant cause of drain blockages in many commercial properties. Over time, tree roots can infiltrate underground pipes in search of water, causing cracks and clogs in the plumbing system. As roots grow, they can block the flow of water, leading to slow drains or even sewage backups.

This is especially problematic for commercial properties with outdoor spaces or those located near older infrastructure, where tree roots may have easy access to underground pipes.

Tip: Schedule regular drain inspections with a plumbing professional to detect and address tree root infiltration before it becomes a major issue.

7. Heavy Rainfall and Stormwater

For commercial properties with outdoor drainage systems, heavy rainfall can cause stormwater to overwhelm the drains. Debris like leaves, dirt, and litter can wash into storm drains, clogging them and preventing proper water drainage. This can result in flooding in parking lots, entryways, and other outdoor areas, disrupting business operations.

Tip: Keep outdoor drains clear of debris, and ensure regular maintenance, especially before and after rainy seasons.

8. Improper Drain Installation

Improper drain installation can also be a source of frequent blockages in commercial properties. If drains are not installed with the correct slope, or if pipes are undersized for the amount of water being processed, blockages are more likely to occur. Inadequate or poorly designed plumbing systems in commercial buildings can lead to recurring issues that require frequent repairs.

Tip: Work with professional plumbers who specialize in commercial properties to ensure that drains are installed correctly and meet local plumbing codes.

Preventing Drain Blockages in Commercial Properties

To avoid costly repairs and disruptions caused by drain blockages, it's essential for commercial property owners and managers to invest in regular drain maintenance. Here are a few preventative measures that can help:

• Regular Drain Inspections: Schedule routine inspections to catch minor issues before they become major blockages.
• Install Drain Strainers: Use strainers in sinks and floor drains to prevent large debris from entering the plumbing system.
• Educate Employees and Tenants: Provide clear instructions on what can and cannot be flushed or washed down drains.
• Invest in Professional Drain Cleaning Services: Regular professional drain cleaning can remove buildup and prevent clogs from forming in the first place.

By taking these preventative steps, you can protect your commercial property from drain blockages, ensuring smooth operations and avoiding unnecessary downtime.
