Tankless Water Heater Leak Detection & Repair

Expert solutions for finding and fixing leaks in on-demand water heating systems

While tankless water heaters are generally more reliable than traditional tank systems, they can still develop leaks that affect performance and cause property damage. At HVACLEAK.ca, we specialize in the detection and repair of leaks in all types of tankless water heating systems.

Common Tankless Water Heater Leak Issues

Internal Component Leaks

  • Heat Exchanger Cracks: From thermal stress or water quality issues
  • Valve and Seal Failures: Due to wear or mineral buildup
  • Internal Pipe Leaks: From corrosion or freeze damage
  • Pressure Relief Valve Issues: Due to excessive pressure or valve deterioration

Connection Leaks

  • Water Inlet/Outlet Connections: From loose fittings or improper installation
  • Gas Line Connections: In gas-powered tankless units
  • Condensate Drain Leaks: In condensing tankless models
  • Venting System Leaks: Causing water intrusion during rain

Warning Signs of Tankless Water Heater Leaks

Watch for These Signs:

  • Water pooling around or beneath the tankless unit
  • Error codes on the unit's display panel
  • Inconsistent water temperature or pressure
  • Unusual noises during operation
  • Higher than normal utility bills
  • Corrosion or mineral buildup visible on connections

Our Tankless Water Heater Leak Detection Process

  1. 1

    Visual Inspection

    We begin with a thorough visual inspection of your tankless water heater, including all connections, valves, and surrounding area to identify obvious leak points.

  2. 2

    Diagnostic Testing

    We run diagnostic tests on your tankless unit to identify any error codes or performance issues that might indicate internal leaks.

  3. 3

    Pressure Testing

    We conduct pressure tests to identify leaks in the water heater system and connected plumbing, measuring pressure changes over time.

  4. 4

    Component Isolation

    For difficult-to-locate leaks, we isolate individual components to determine the exact source of the leak within the tankless system.
