Are you shocked every time you receive your water bill? If your usage hasn’t changed but your bill keeps increasing, hidden plumbing problems could be the culprit. Leaks, inefficient fixtures, or even underground pipe issues can silently waste water—and money. At Plomberie Viau, we specialize in identifying and fixing plumbing problems that could be driving up your utility costs. In this article, we’ll uncover the most common hidden plumbing issues causing high water bills and how to fix them.

1. Hidden Leaks in Pipes

Even a small leak can waste thousands of liters of water over time. Leaks in walls, floors, or underground pipes often go unnoticed until they cause significant damage.

How to Detect & Fix It:

• Look for unexplained damp spots, mold growth, or musty smells.
• Check your water meter before and after a two-hour period of no water use—if it moves, you likely have a leak.
• Call a professional plumber like Plomberie Viau to perform a leak detection test.

2. Running Toilets

A running toilet can waste up to 200 gallons (750 liters) of water per day, making it one of the biggest culprits behind high bills.

How to Fix It:

• Open the tank and inspect the flapper valve—if it’s worn out, replace it.
• Adjust the float to ensure the tank doesn’t overfill.
• If problems persist, consider replacing the fill valve or flushing mechanism.

3. Dripping Faucets & Showerheads

A faucet that drips once per second can waste over 11,000 liters of water per year!

Prevention & Fixes:

• Replace worn-out washers or O-rings inside the faucet.
• Install low-flow aerators to reduce water waste.
• If the leak is from the base of the faucet, it may be time for a replacement.

4. Faulty Water Softeners or Filtration Systems

Malfunctioning water softeners or filtration systems can cause constant water cycling, leading to excessive water waste.

How to Detect & Fix It:

• Listen for unusual sounds from your water softener regenerating too often.
• Check the unit’s settings to ensure it’s not cycling more frequently than needed.
• Schedule a professional maintenance check to prevent unnecessary waste.

5. Underground Pipe Leaks

If you notice wet patches in your yard or unexplained drops in water pressure, you might have an underground leak.

Signs of Underground Leaks:

• A sudden increase in your water bill.
• Cracks in your home’s foundation.
• Puddles or unusually green patches in your lawn.

Professional plumbers at Plomberie Viau use advanced leak detection tools to identify and repair underground leaks without unnecessary digging.

6. Inefficient Appliances & Fixtures

Older appliances and outdated plumbing fixtures use far more water than modern, water-efficient models.

How to Save Water:

• Upgrade to Energy Star-rated dishwashers and washing machines.
• Replace old toilets with dual-flush or low-flow models.
• Install motion-sensor or touchless faucets to control water usage.

7. High Water Pressure

Excessive water pressure may feel great in the shower, but it can damage your pipes and cause leaks over time.

How to Fix It:

• Use a water pressure gauge to check if your home’s pressure exceeds 60 psi.
• Install a pressure-reducing valve (PRV) if your pressure is too high.

8. Leaking Water Heater

A leaking water heater not only wastes water but also increases your energy bill.

Signs of a Water Heater Leak:

• Puddles forming around the base of the heater.
• Rust-colored water coming from taps.
• A sudden drop in hot water supply.

If you suspect a water heater issue, contact a plumber immediately to prevent major damage.
