Common Plumbing Problems in Commercial Buildings & How to Fix Them

Plumbing issues in commercial buildings can be disruptive, costly, and even hazardous. Whether you own an office, restaurant, retail store, or apartment complex in Watertown, Beaver Dam, or Oconomowoc, plumbing problems can impact your business operations and customer experience. Here are some of the most common plumbing issues in commercial properties and how to fix them.

1. Clogged Drains & Toilets

Why It Happens:

• High usage in restrooms
• Grease, food waste, or debris in drains
• Flushing non-flushable items (wipes, paper towels, hygiene products)

How to Fix It:

• Use drain strainers to prevent blockages
• Educate employees and customers on what not to flush
• Schedule routine drain cleaning with a professional plumber

A clogged drain can quickly turn into a major issue—don’t wait until it overflows!

2. Leaky Pipes & Faucets

Why It Happens:

• Worn-out washers or seals
• High water pressure
• Pipe corrosion

How to Fix It:

• Repair leaks early to prevent structural damage
• Inspect pipes regularly for rust or moisture buildup
• Upgrade old pipes in aging buildings

Even a small leak can waste thousands of gallons of water, increasing utility costs.

3. Sewer Line Backups

Why It Happens:

• Tree roots invading sewer pipes
• Grease buildup from restaurant kitchens
• Flushing large objects down toilets

How to Fix It:

• Schedule regular sewer line inspections
• Use hydro jetting to clear blockages
• Install grease traps in commercial kitchens

A sewer backup can lead to foul odors, slow drains, and even business shutdowns—act fast!

4. Water Heater Failures

Why It Happens:

• Sediment buildup inside the tank
• Thermostat malfunctions
• Lack of maintenance

How to Fix It:

• Flush the water heater annually to remove sediment
• Inspect heating elements regularly
• Consider upgrading to a tankless water heater for efficiency

Businesses that rely on hot water—like restaurants, hotels, and healthcare facilities—can’t afford a failing water heater.

5. Low Water Pressure

Why It Happens:

• Clogged pipes
• Leaks in the plumbing system
• Issues with the municipal water supply

How to Fix It:

• Check for leaks that could be reducing pressure
• Clean aerators and pipes to remove buildup
• Install a booster pump if necessary

Low water pressure can impact everything from handwashing in restrooms to dishwashing in kitchens.

6. Backflow Issues

Why It Happens:

• Water pressure changes
• Improper plumbing connections
• Lack of a backflow prevention device

How to Fix It:

• Install a backflow prevention device
• Have your system inspected annually
• Ensure compliance with Wisconsin plumbing codes

Backflow can contaminate your water supply, putting employees and customers at risk.
