Commercial plumbing systems are essential for businesses, ensuring a reliable water supply and proper drainage. However, due to their complexity and heavy usage, these systems often encounter problems that can lead to costly repairs and operational disruptions. In this guide, we will discuss common commercial plumbing issues and practical solutions to fix them.
1. Leaky Faucets and Pipes
Causes:
- Worn-out washers or seals
- Corroded pipes
- High water pressure
- Loose pipe fittings
Fixes:
- Replace washers and seals – This is a simple fix for dripping faucets.
- Tighten fittings – Secure loose connections to prevent leaks.
- Patch small leaks – Use pipe sealant or plumber’s tape as a temporary fix.
- Replace damaged pipes – Severely corroded or cracked pipes should be replaced by a professional plumber.
2. Clogged Drains and Sewer Backups
Causes:
- Accumulation of grease, food particles, and debris
- Flushing non-biodegradable materials
- Tree root intrusion in underground pipes
- Pipe scaling and sediment buildup
Fixes:
- Use drain strainers – Prevents debris from entering the drainage system.
- Apply commercial drain cleaners – Use enzymatic or chemical drain cleaners carefully.
- Schedule hydro jetting – High-pressure water jets can clear tough clogs.
- Inspect for root damage – Use a plumber’s camera to check for tree root intrusion and remove them with professional tools.
3. Low Water Pressure
Causes:
- Pipe corrosion or sediment buildup
- Leaks in the plumbing system
- Issues with the municipal water supply
- Faulty pressure regulators
Fixes:
- Clean aerators and filters – Remove debris from faucets and showerheads.
- Check for leaks – Identify and repair any visible leaks.
- Replace corroded pipes – Older pipes may need upgrading.
- Install a water pressure booster – Helps regulate water pressure in large buildings.
4. Running Toilets
Causes:
- Faulty flapper valve
- Improperly adjusted float
- Water supply issues
Fixes:
- Replace the flapper valve – If it doesn’t seal properly, water will continuously flow.
- Adjust the float level – Ensure the water shuts off at the correct level.
- Check for silent leaks – Add food coloring to the tank; if the color appears in the bowl, there's a leak that needs fixing.
5. Water Temperature Issues
Causes:
- Malfunctioning water heater
- Sediment buildup in the tank
- Thermostat problems
Fixes:
- Flush the water heater – Removes sediment that affects performance.
- Check the thermostat settings – Ensure it's set to the desired temperature.
- Inspect heating elements – Replace defective parts if necessary.
- Upgrade to a commercial-grade water heater – If the existing one is outdated, consider replacing it with a high-capacity model.
6. Backflow Problems
Causes:
- Cross-connections between clean and contaminated water
- Failure of backflow prevention devices
- Pressure imbalances in the plumbing system
Fixes:
- Install or inspect backflow preventers – Regular maintenance of these devices is essential.
- Test water pressure regularly – Ensures proper flow and prevents contamination.
- Work with a licensed plumber – Backflow issues should be handled by professionals to maintain health and safety compliance.
7. Burst Pipes
Causes:
- Freezing temperatures
- Excessive water pressure
- Corrosion and aging pipes
Fixes:
- Insulate pipes – Prevents freezing in cold weather.
- Monitor water pressure – Keep it within safe limits using a pressure regulator.
- Replace aging pipes – Avoid burst risks by upgrading old plumbing.
- Turn off the water supply – In case of a burst, immediately shut off the main valve and call a plumber.
8. Foul Odors from Drains
Causes:
- Dry P-traps allowing sewer gases to escape
- Buildup of organic matter in pipes
- Sewer line leaks or blockages
Fixes:
- Flush P-traps with water – Prevents gas leaks by keeping the trap full.
- Use baking soda and vinegar – A natural cleaner that eliminates odors.
- Schedule a professional drain cleaning – Removes buildup causing unpleasant smells.
- Inspect sewer lines – Check for cracks or blockages with a plumbing camera.

Commercial plumbing issues can disrupt business operations and lead to costly repairs if not addressed promptly. Regular maintenance, timely inspections, and working with professional plumbers can help prevent and resolve common plumbing problems efficiently.
