Why Water Heater Issues Happen 💧

Water heaters work hard—day in and day out. Over time, wear and tear, sediment build-up, and mechanical failures can cause a range of problems. Knowing what to look for makes all the difference, helping you prevent small annoyances from becoming major emergencies.

Common Water Heater Problems and How to Troubleshoot 🛠️

Let’s break down the most frequent issues and what homeowners can do safely before reaching for the phone.

1. No Hot Water at All 🥶

Possible Causes:

  • Power supply issues (tripped breaker, blown fuse)
  • Faulty thermostat
  • Broken heating element (electric) or thermocouple (gas)
  • Pilot light out (gas heaters)

Safe Troubleshooting Steps:

  • Check the Power: For electric heaters, make sure the unit is plugged in and the breaker hasn’t tripped.
  • Inspect the Pilot Light: For gas heaters, carefully check and relight if you’re comfortable. If it keeps going out, call a pro!
  • Adjust the Thermostat: Sometimes it’s set too low.

When to Call Sears Plumbing:

  • If the breaker keeps tripping or the pilot won’t stay lit
  • Strange smells, gas odors, or visible wiring issues
  • No hot water after basic troubleshooting

2. Water Leaks Around the Heater 🚨

Possible Causes:

  • Loose inlet/outlet connections
  • Corroded tank or fittings
  • Faulty pressure relief valve

Safe Troubleshooting Steps:

  • Turn Off Power/Gas: Always shut off power or gas before inspecting.
  • Check Water Connections: Tighten if visibly loose (but don’t overtighten).
  • Inspect the Drain Valve: Ensure it’s fully closed.

When to Call Sears Plumbing:

  • Water pooling under the tank
  • Leaking from seams or bottom of the tank (sign of tank failure)
  • Rusty or discolored water

Leaks can quickly escalate to water damage—don’t wait!

3. Discolored or Rusty Water 🟤

Possible Causes:

  • Corroded tank lining
  • Failing anode rod
  • Rusty pipes

Safe Troubleshooting Steps:

  • Run the hot water tap for a few minutes.
  • If only hot water is discolored, it points to the heater.
  • If all water is discolored, the issue may be with your plumbing system.

When to Call Sears Plumbing:

  • Persistent rusty water from hot taps
  • Water smells metallic or odd

Professional inspection is essential—it might be time for water heater replacement or repiping.

4. Strange Noises: Popping, Rumbling, or Banging 🔊

Possible Causes:

  • Sediment build-up at the bottom of the tank
  • Overheating water trapped under sediment

Safe Troubleshooting Steps:

  • Flush the Tank: You can drain a small amount of water to remove sediment (see your owner’s manual).
  • Listen for Patterns: Occasional pops can be normal, but regular loud noises are not.

When to Call Sears Plumbing:

  • Persistent or worsening noises
  • Sediment flush doesn’t resolve the problem

Ignoring these sounds can lead to tank damage and leaks!

5. Water Takes Too Long to Reheat ⏳

Possible Causes:

  • Faulty heating element or thermostat
  • Sediment build-up
  • Undersized unit for your household

Safe Troubleshooting Steps:

  • Check the thermostat is set between 120–140°F (49–60°C).
  • Limit simultaneous hot water use.

When to Call Sears Plumbing:

  • Water never gets hot enough
  • Tank recovers extremely slowly

6. Low Hot Water Pressure 🚿

Possible Causes:

  • Sediment or mineral scale in pipes or tank
  • Partially closed shutoff valve
  • Plumbing system issues

Safe Troubleshooting Steps:

  • Check the main water shutoff and heater shutoff valves are fully open.
  • Flush the heater to clear sediment, if safe and accessible.

When to Call Sears Plumbing:

  • Sudden, severe drop in pressure
  • Ongoing low pressure despite basic checks
