Losing hot water suddenly can disrupt your entire day — from morning showers to washing dishes and running your business smoothly. Tankless water heaters are known for their efficiency and endless hot water supply, but like any plumbing system, they can occasionally fail without warning. If you’re dealing with a sudden breakdown, knowing when to call for Tankless Water Heater Repair Mississauga services and how related plumbing issues — including outdated Kitec Pipe Fittings — can impact performance is essential.
Understanding Your Tankless Water Heater System
Before diving into emergency procedures, it's helpful to understand how your tankless water heater operates. Unlike traditional tank systems that store hot water, tankless units heat water on demand as it flows through the device.
Common Reasons You Suddenly Lose Hot Water
Understanding the most common causes can help you explain the problem clearly when requesting Tankless Water Heater Repair Mississauga services.
1. Mineral Buildup and Hard Water
Mississauga’s hard water can cause mineral deposits to accumulate inside the heat exchanger. Over time, this buildup reduces efficiency and may trigger system shutdowns to prevent damage.
2. Electrical or Gas Supply Issues
Power outages, tripped breakers, or gas supply interruptions can prevent your heater from functioning. Even a minor wiring problem can stop the unit entirely.
3. Overloaded System Demand
Tankless heaters provide continuous hot water, but they still have capacity limits. Running multiple appliances simultaneously can exceed the unit’s output.
4. Ignition or Burner Malfunctions
Gas-powered systems rely on a functioning ignition system. Faulty sensors or clogged burners can prevent water from heating properly.
5. Plumbing Problems and Kitec Pipe Fittings
Older homes in the region may still contain Kitec Pipe Fittings, which are known for deterioration and potential leaks.
Immediate Steps to Take During a Hot Water Emergency
When you suddenly lose hot water, don't panic. Follow these practical steps before calling for emergency repair:
Step 1: Check the Obvious Issues
Start with the basics. Verify that your tankless water heater has power and that gas valves are open if you have a gas-powered unit.
Step 2: Look for Error Codes
Check your tankless water heater's display panel for any error codes. Write down or photograph these codes as they provide valuable diagnostic information for repair technicians.
Step 3: Reset Your Unit
Many tankless water heater problems can be temporarily resolved with a simple reset. Turn off the power to your unit, wait 30 seconds, then turn it back on.
Step 4: Check Water Supply and Pressure
Ensure your home's main water supply is functioning properly. Low water pressure throughout your house can prevent your tankless heater from operating.
Step 5: Inspect for Visible Leaks
Leaks can indicate serious problems that require immediate professional attention to prevent water damage to your home.

The Hidden Risk of Kitec Pipe Fittings in Mississauga Homes
If your Mississauga home was built or underwent plumbing renovations between 1995 and 2007, there's a possibility it contains Kitec Pipe Fittings. Kitec was a popular plumbing system during this period, but it has since been found to be defective and prone to premature failure.
How Kitec Affects Tankless Water Heaters
Reduces water pressure, affecting heating performance
Increases risk of leaks near the heater
Causes sediment buildup inside the system
May void warranties for newer water heaters
If your home has Kitec Pipe Fittings, a professional inspection during your repair service is highly recommended.
Preventive Maintenance: Avoiding Future Emergencies
The best emergency is the one that never happens. Regular maintenance of your tankless water heater can prevent most unexpected failures and extend your system's lifespan significantly.
Annual Professional Maintenance
Schedule yearly maintenance with Harb Plumbing to keep your tankless water heater operating efficiently. Professional technicians will descale your unit, clean filters, inspect all components, and identify potential problems before they cause system failures.
Regular Filter Cleaning
Most tankless water heaters have inlet filters that prevent debris from entering the unit. These filters should be checked and cleaned every few months, especially if you have hard water or older plumbing that may contain Kitec Pipe Fittings or other deteriorating materials.
Water Quality Management
Hard water is the enemy of tankless water heaters. Mineral buildup reduces efficiency and can cause complete system failure. Consider installing a water softener or descaling system to protect your investment and ensure consistent hot water delivery.
