Common Water Heater Repair Scenarios
No Hot Water
Complete loss of hot water from a tank or tankless unit. Could be a failed heating element, thermostat, or gas valve issue.
Leaking Water Heater
Water pooling around the base of your tank is urgent — it can mean a failing tank that could rupture and flood your home.
Strange Noises or Smells
Popping, banging, or rumbling from your water heater signals sediment buildup. A sulfur smell may indicate a failing anode rod or gas leak.
Water Heater Replacement
Units over 10-12 years old that need frequent repairs are usually better replaced. Modern units are more efficient and reliable.
