Our Approach to Hot Water Repairs

Not all repairs make sense. An honest repair technician will tell you when a repair is good value, and when you’re better off putting that money toward a new system.

We diagnose thoroughly and advise honestly. If your system can be repaired safely and economically, we’ll do it properly. If repair doesn’t make sense, we’ll explain why and discuss your options.

Common Hot Water Problems We Fix

No Hot Water at All

Possible causes:

  • Tripped circuit breaker or blown fuse
  • Failed heating element (electric)
  • Pilot light out (gas)
  • Thermostat failure
  • Gas supply issues

Our approach: We diagnose the root cause and assess whether the system is worth repairing based on age and overall condition.

Not Enough Hot Water

Possible causes:

  • Element partially failed (electric)
  • Sediment buildup reducing capacity
  • Thermostat set too low
  • Tank too small for household
  • Mixing valve issues

Our approach: We determine whether this is a repairable issue or a sign of system decline.

Water Too Hot or Too Cold

Possible causes:

  • Thermostat failure
  • Tempering valve malfunction
  • Mixing valve issues
  • Controller problems (heat pump/solar)

Our approach: Temperature issues can be safety concerns. We prioritise diagnosis and repair of these issues.

Leaking System

Possible causes:

  • Tank corrosion (often not repairable)
  • Pressure relief valve discharge
  • Pipe connection leaks
  • Fitting failures

Our approach: Tank leaks usually mean replacement. Connection and valve leaks are often repairable.

Strange Noises

Possible causes:

  • Sediment buildup
  • Element scale
  • Pressure issues
  • Pump problems (heat pump/solar)

Our approach: Noises often indicate developing problems. Early diagnosis can prevent bigger issues.

When We Recommend Repair

Repair generally makes sense when:

  • System is within expected lifespan (under 10 years typically)
  • Issue is isolated to specific component
  • Repair cost is well below 50% of replacement
  • System is otherwise efficient and working well
  • Compliance issues are minor

When We Recommend Replacement

We advise replacement when:

  • System is near or past expected lifespan
  • Repair costs approach replacement value
  • Multiple components are failing
  • Tank integrity is compromised
  • System is significantly inefficient
  • Major compliance work is needed

The Repair vs Replace Decision

Here’s a practical framework:

System AgeRepair Cost vs ReplacementRecommendation
Under 5 yearsAny reasonable repairRepair
5-8 yearsUnder 30% of replacementRepair
8-10 yearsUnder 20% of replacementConsider carefully
Over 10 yearsMultiple issuesUsually replace

We apply this thinking to your specific situation with honest advice.

Frequently Asked Questions

How do I know if I should repair or replace?

expand_more

General rule: if repair costs exceed 50% of replacement value, or your system is over 10-12 years with multiple issues, replacement usually makes more sense. Read our [repair vs replace guide](/blog/hot-water-system-repair-vs-replace-guide/) for detailed criteria.

Do you charge for diagnosis?
