Hot Water Repairs Perth | ASAP Trades

No Hot Water at All

The most obvious problem – turning on a hot tap and getting only cold water. This frustrating situation can indicate several issues:

• Faulty or burned-out heating element in electric systems
• Pilot light extinguished or ignition failure in gas systems
• Faulty thermostat not triggering the heating system
• Tripped safety switch cutting power to the system
• Gas supply issues affecting gas hot water systems
• Empty gas bottle for LPG systems

Our plumbers quickly diagnose which component has failed and repair or replace it to restore your hot water.

Not Enough Hot Water

If hot water runs out too quickly or doesn’t get hot enough, you might have:

• Undersized hot water system for your household’s needs
• Faulty thermostat set too low or not functioning correctly
• Sediment buildup in the tank reducing available capacity
• One failed heating element in dual-element electric systems
• Faulty tempering valve mixing too much cold water
• Deteriorating sacrificial anode allowing corrosion

We’ll assess whether repair or system upgrade is the most cost-effective solution for your household.

Water Too Hot or Inconsistent Temperature

Unpredictable water temperature that’s scalding hot or fluctuates indicates:

• Faulty thermostat needing calibration or replacement
• Tempering valve requiring adjustment or replacement
• Heating element problems causing temperature spikes
• Pilot light or burner issues in gas systems
• Faulty gas valve not regulating flame properly

Consistent, safe water temperature is essential, especially in homes with children or elderly residents.

Leaking Hot Water Tank or Fittings

Leaks from your hot water system require immediate attention to prevent water damage:

• Tempering valve or pressure relief valve leaking (often repairable)
• Tank corrosion causing leaks (usually requires replacement)
• Loose fittings or connections (easily tightened or resealed)
• Split or damaged inlet/outlet pipes
• Leaking drain valve at the base of the tank

We’ll identify whether the leak is repairable or if tank replacement is necessary.

Strange Noises from Hot Water System

Rumbling, popping, hissing, or banging sounds can mean:

• Sediment buildup causing water to boil and trap under sediment
• Heating element scaling reducing efficiency and causing noise
• Loose heating element rattling during operation
• Expanding and contracting tank making popping sounds
• High water pressure causing pipe vibration

Regular maintenance prevents most noise issues, but we can clean and service noisy systems.

Discoloured or Smelly Hot Water

Brown, rusty, or metallic-smelling water from hot taps indicates:

• Corroded sacrificial anode needing urgent replacement
• Significant sediment buildup in the storage tank
• Bacteria growth in solar hot water systems
• Internal tank corrosion (may require replacement)
• Degraded internal lining exposing metal

Clean, clear hot water is essential for health and comfort. We’ll identify and fix the cause.

Pilot Light Won’t Stay Lit (Gas Systems)

For gas hot water systems with pilot lights:

• Faulty thermocouple not sensing pilot flame correctly
• Weak or intermittent gas supply to the pilot
• Blocked pilot light orifice restricting gas flow
• Faulty gas control valve not maintaining pilot
• Draft issues blowing out the pilot flame

Modern gas systems with electronic ignition have different fault causes that we can diagnose and repair.
