Diagnosing the Leak

Tankless water heaters often conceal leaks within their internal components, making it crucial to isolate the source accurately. Electrical leaks are distinct from water leaks, requiring different repair approaches. Begin by identifying the specific location of the water leak. Common areas include:

• Connections: Inspect the inlet and outlet water connections for loose, damaged, or corroded fittings or pipes.
• Heat exchanger: Look for leaks at the joints or seams of the heat exchanger, which is responsible for transferring heat from the burner to the water.
• Pressure relief valve: A leaking pressure relief valve can indicate excessive water pressure or a faulty valve.
• Drain valve: If the drain valve is not properly closed or is damaged, water may leak from this component.

Common Leak Types and Solutions

1. Loose Connections: Use a wrench to tighten any loose connections at the inlet and outlet pipes. Replacing corroded or damaged pipes or fittings may be necessary.

2. Leaking Heat Exchanger: While heat exchanger leaks require professional assistance, try the following before calling a plumber:

   • Shut off the gas supply to the water heater.
   • Close the water supply valves.
   • Disconnect the water heater from the electrical supply.

3. Faulty Pressure Relief Valve: Replace a damaged or malfunctioning pressure relief valve. Ensure the new valve is compatible with your model and has an appropriate pressure rating.

4. Leaking Drain Valve: Tighten the drain valve or replace it if it’s worn or damaged.

Maintenance and Prevention Tips

Prevent future leaks by following these expert tips:

• Annual Inspection: Schedule regular inspections by a qualified plumber to identify potential leaks and other issues early on.
• Regular Flushing: Flush your tankless water heater every few months to remove sediment that can contribute to leaks.
• Soft Water Supply: Install a water softener to minimize scale buildup and extend the lifespan of your water heater.
• Winterization: If you reside in a freezing climate, protect your water heater from frozen pipes by draining the water completely before winter.
