Common Water Heater Problems We Fix

No Hot Water

If your water heater isn’t producing hot water, the issue may be with the heating element, gas supply, or thermostat.

Water Heater Leaks

A leaking water heater could be caused by a faulty pressure relief valve, corroded tank, or loose plumbing connections.

Strange Noises (Rumbling or Banging Sounds)

If your water heater makes popping or banging noises, sediment buildup may be overheating the tank, reducing efficiency.

Discolored or Rusty Water

Brown or rusty water coming from your taps may be a sign of corrosion inside your water heater or a failing anode rod.

Water Takes Too Long to Heat

A malfunctioning thermostat, heating element, or sediment buildup can slow down the heating process.

Inconsistent Water Temperatures

If your water fluctuates between hot and cold, it could be a thermostat or heating element issue.

Low Hot Water Pressure

Sediment buildup or pipe corrosion can restrict water flow, leading to low hot water pressure.
