Common Water Heater Issues We Fix

From minor valve replacements to major tank leaks, we’ve seen—and fixed—it all. Here are some of the most common water heater issues we repair:
plumbing

No Hot Water

No hot water could mean a failed heating element (in electric models), a pilot light issue (in gas models), or a broken thermostat. We identify the cause quickly and get your system up and running again.

Leaking Tank

A water heater tank leak can cause significant water damage and mould growth. We pinpoint the source of the leak—whether from a valve, connection, or the Tank itself—and perform necessary repairs or recommend a replacement.

Strange Noises

Popping, rumbling, or high-pitched whines? These sounds often signal sediment buildup or overheating. We flush the system or repair internal components as needed.

Pilot Light Problems

If your gas water heater’s pilot light does not light, it could be due to a faulty thermocouple, a dirty burner, or a problem with the gas valve. Our team troubleshoots and resolves the problem safely.

Inconsistent Temperature

If your hot water swings from lukewarm to scalding, your thermostat or mixing valve may be malfunctioning. We recalibrate or replace these components.

Faulty Thermostat or Valve

Malfunctioning thermostats and pressure relief valves can compromise both comfort and safety. We test and replace them to restore proper function.
