Introduction
Running a commercial property comes with a long list of responsibilities, and plumbing isn’t always top of mind until something goes wrong. But ignoring the early signs of a problem can lead to expensive repairs, health code violations, or even business interruptions.
Whether you manage an office, retail space, restaurant, or industrial facility in B.C., knowing the red flags of plumbing trouble helps you take action before it escalates. Here’s what to watch for.
1. Unexpected Water Bills
If your water bill suddenly increases without a clear reason, there’s likely a hidden issue. Leaks, constantly running toilets, or malfunctioning irrigation systems can waste thousands of litres of water.
Compare current and past utility statements. Even a moderate increase might point to something hidden behind walls or underground. In multi-unit properties, individual fixture problems can add up fast.
2. Frequent Drain Clogs
One clogged sink doesn’t mean much. But if multiple drains back up regularly, or if slow drainage keeps coming back even after plunging, it’s time for a closer look.
Recurring clogs might be due to:
- Grease or debris buildup in main lines
- Foreign objects flushed into the system
- Tree roots breaking into underground pipes
Drain cleaning and video inspections from Cohesive Mechanical can help identify the exact cause before it disrupts your operation.
3. Low Water Pressure
Low pressure in one faucet can be a simple fix. But if pressure drops across your property, it could signal a much larger issue:
- Corroded or scaled pipes
- Leaks in the system
- Pressure regulator failure
- Partially closed shut-off valves
Low pressure not only affects functionality but can frustrate staff and customers. If you can’t isolate the issue, it’s best to schedule a professional inspection.
4. Discoloured Water
Brown, yellow, or cloudy water usually means there’s corrosion or sediment in the plumbing. If your property is older, galvanized steel pipes could be breaking down from the inside.
This isn’t just a visual concern, it may affect taste, smell, and even safety. Discoloured water should never be ignored in a business, especially in restaurants or clinics where sanitation is critical.
5. Water Stains or Mould
Water stains on ceilings, floors, or walls suggest a hidden leak. Mould or mildew growth often follows if moisture isn’t addressed quickly. Beyond structural damage, these issues can pose health risks.
Routine visual inspections can help you catch these signs early. If your tenants or employees mention musty smells, follow up immediately, leaks don’t fix themselves.
6. Unusual Noises
Noises in a commercial plumbing system may be easy to overlook in a busy setting. But gurgling drains, banging pipes, or high-pitched whistling could signal trouble like:
- Air trapped in the lines
- Water hammer from high pressure
- Loose pipe supports
- Valve issues
These sounds usually point to a mechanical problem, something that can wear out parts or lead to a sudden failure.
7. Constantly Running Toilets
One faulty toilet can waste hundreds of litres a day. Multiply that across several stalls in a business or public facility, and the waste adds up fast.
This issue is often caused by:
- Worn-out flappers
- Faulty fill valves
- Improper float settings
Besides wasting water, a malfunctioning toilet can reflect poorly on your business. It’s a quick repair that makes a noticeable difference.
8. Old or Outdated Fixtures
Even if nothing seems “wrong,” older fixtures may be using more water than necessary and may be prone to failure.
Signs it’s time for an upgrade:
- Original plumbing more than 20 years old
- Outdated toilets or faucets that lack water-saving features
- Frequent minor repairs adding up in cost
Modern fixtures not only lower operating costs but also reflect your commitment to maintenance and sustainability, something tenants and customers appreciate.
Why Commercial Plumbing Issues Demand Fast Action
In a commercial setting, the consequences of a plumbing problem are magnified:
- Loss of revenue from downtime

- Property damage that affects multiple units

A Quick Checklist for Commercial Plumbing Red Flags
Keep this checklist handy for regular walkthroughs:
- Do your utility bills show unexplained spikes?
- Are any faucets or toilets leaking, even slightly?
- Is water pressure noticeably low?
- Are there signs of moisture or mould?
- Do you hear banging or gurgling from pipes?
- Are employees or tenants complaining about drains or smells?
- Is your plumbing system more than 15–20 years old?
If you answered “yes” to any of these, it may be time to call a professional.
