Signs Your Hot Water System Needs Repair or Assessment

Common Hot Water System Problems

Changes in water temperature, pressure or system performance can indicate that your hot water system needs professional attention.

Contact a plumber if you notice:

• No hot water
• Water that is only lukewarm
• Water temperature changing unexpectedly
• Hot water running out faster than usual
• A visible leak around the hot water system
• Water dripping continuously from an unexpected location
• Rust-coloured or discoloured hot water
• Unusual banging, popping or rumbling noises
• Reduced pressure at hot water outlets
• Repeated loss of operation
• Corrosion around the tank, valves or connections

Some hot water problems may involve electrical or gas components. Do not remove system covers or attempt internal repairs yourself. The appropriate licensed trade will depend on the cause of the fault.

Why Is Water Leaking From the Hot Water System?

Water around a hot water system does not always mean that the storage tank has failed. A leak may be coming from a valve, pipe connection, fitting or another nearby source.

Some valves may discharge small amounts of water during normal system operation. However, continuous, excessive or unexpected water discharge should be assessed to determine whether maintenance or repairs are required.

A leaking storage tank is generally more serious because damage to the tank itself may not be repairable. If water is actively spreading and it is safe to do so, isolate the relevant water supply and contact a plumber, particularly where the leak could damage the surrounding property or reach electrical equipment.

Why Has the Hot Water Temperature Changed?

Hot water that becomes too cold, too hot or inconsistent can have several possible causes.

These may include:

• A hot water system fault
• Control or thermostat problems
• Gas supply or burner concerns
• Electrical faults
• A tempering valve issue
• Sediment or deterioration within the system
• Increased hot water demand
• A system that is undersized for the property's current use

Because hot water systems can involve plumbing, electrical and gas components, the trade required to complete the repair will depend on the cause identified during the assessment.

Why Does the Hot Water Run Out So Quickly?

A reduction in available hot water can indicate that the system is no longer heating its full volume, is losing heat, has developed a component fault or is no longer large enough for the property's demand.

Before contacting a plumber, consider whether anything has recently changed, such as:

• More people using the property
• Longer or more frequent showers
• New appliances or plumbing fixtures
• The problem beginning suddenly
• The hot water system taking longer to recover
• Water temperature becoming lower than previously

This information can help distinguish between a capacity issue and a fault with the hot water system itself.

 

Should You Repair or Replace Your Hot Water System?

When Is Hot Water System Repair Worth Considering?

A hot water system repair may be practical when the main unit remains in reasonable condition and the problem can be traced to a serviceable or replaceable component.

Repair may be worth considering when:

• The hot water system is otherwise in reasonable condition
• The fault involves a replaceable valve or accessible component
• There is no significant tank corrosion or structural leakage
• Suitable replacement parts are still available
• The system has not experienced repeated recent failures
• The existing capacity still suits the property
• The repair cost is reasonable compared with replacement

Servicing may also be recommended where the system is still operating but showing early signs of declining performance.

When Is Hot Water System Replacement More Practical?

Hot water system replacement may provide better long-term value where the existing unit has significant damage, repeated faults or no longer suits the requirements of the property.

Replacement may be the more practical option when:

• The storage tank itself is leaking
• There is extensive corrosion
• The hot water system has failed several times
• Replacement parts are unavailable or uneconomical
• The existing system is no longer large enough for the property
• The installation does not suit planned renovations or future use
• The repair cost and expected remaining service life do not provide good value
• The system location or existing plumbing arrangement requires a broader upgrade

A hot water system should not automatically be replaced simply because of its age. The condition, performance, repair history and suitability of the existing system should all be considered before deciding whether replacement is necessary.

Should You Replace a Hot Water System Before It Fails?

Planned hot water system replacement may be worth considering when an existing unit shows visible corrosion, has required repeated repairs or is installed in a location where a sudden leak could cause significant property damage.

Planning ahead provides more time to compare suitable replacement systems, confirm any plumbing, gas or electrical requirements and arrange the work without the pressure created by a complete system failure.

However, an older system that remains serviceable and continues to meet the property's hot water requirements does not necessarily need immediate replacement. Its current condition and performance remain important factors.

 

Choosing and Arranging Hot Water System Services

What Factors Affect Hot Water System Selection?

A replacement hot water system should be selected according to the property and expected demand rather than simply choosing the cheapest available unit.

Important considerations can include:

• Number of occupants or regular users
• Peak hot water demand periods
• Residential, commercial or property type
• Available installation space
• Existing gas and electrical services
• Existing plumbing and pipework
• Hot water system installation location
• Access for removal and replacement
• Current or planned renovations
• Commercial or high-use requirements
• Product specifications and warranty conditions

An incorrectly sized or poorly positioned hot water system can create ongoing performance, access or maintenance problems. The replacement should suit both the current installation and the property's expected future use.

What Information Should You Send the Plumber?

Providing clear information before the appointment can help the plumber understand the problem and determine what preparation may be required.

Where possible, provide:

• Property address
• Photographs of the full hot water system
• Clear photographs of labels or model information
• System type, if known
• A description of the fault
• When the problem first began
• Whether water is actively leaking
• Number of people regularly using the system
• Any recent repair or servicing history
• Property or installation access restrictions

This information can help determine the likely scope of the issue and whether the situation requires more immediate attention.

Signs and Common Causes of Blocked Drains

Common Signs of a Blocked Drain

A complete blockage is usually obvious, but many drainage problems develop gradually. Identifying the early signs of a blocked drain can help prevent an overflow or more disruptive drainage problem.

Common warning signs include:

• Water draining more slowly than usual
• Gurgling sounds from sinks, toilets or floor wastes
• Unpleasant smells coming from drains
• Water rising in a nearby fixture when another is used
• A toilet that does not clear normally
• Repeated blockages in the same sink, shower or external drain
• Water or wastewater overflowing from an external access point
• Damp ground or pooling near a drainage line

One symptom does not always confirm the cause. A slow sink may have a blockage close to the fixture, while gurgling or slow drainage across several areas can indicate a restriction further along the drainage system.

Hair, Soap and Personal-Care Products

Bathroom drains regularly collect hair, soap residue and product build-up. Over time, this material can narrow the available opening inside the waste and catch additional debris passing through the drain.

A removable waste grate or strainer can help reduce the amount of hair and material entering the drainage system, but it will not prevent every blockage. If a shower or basin repeatedly drains slowly after accessible debris has been removed, further investigation may be required.

Grease, Fat and Food Waste

Cooking grease, oils and food residue can build up inside kitchen drainage. Even fats that enter the sink as a liquid can cool and harden further along the pipework, restricting the internal diameter of the drain.

Fats and oils should be allowed to cool and disposed of appropriately rather than being washed down the sink. Removing food scraps before rinsing dishes and cookware can also help reduce avoidable kitchen drain blockages.

Wipes and Other Unsuitable Items

Many products do not break down in drainage systems in the same way as toilet paper. Wipes, sanitary products, paper towel and other foreign objects can become lodged within toilet connections or sewer drainage.

Products labelled as flushable may still contribute to blockages depending on the product, pipework and wider drainage system. A practical rule is to flush only toilet paper and human waste.

Tree Roots in Underground Drains

Tree roots can enter underground drainage through cracks, failed joints or damaged sections of pipework. Once roots enter the drain, they can continue to grow and catch waste moving through the pipe.

Clearing the immediate obstruction may restore drainage flow, but recurring root-related blockages can indicate that the affected section of pipe also requires repair or replacement.

Damaged or Displaced Drainage Pipework

Older drainage systems, ground movement, construction activity and previous installation issues can cause pipes to crack, collapse or move out of alignment. Damaged pipework can restrict flow and create points where waste repeatedly collects.

Where the drain and available access points are suitable, a CCTV drain inspection can help identify the condition and location of damaged or displaced pipework.

Construction Debris and Sediment

Sand, grout, cement residue, soil and other construction debris can enter drainage systems during building, renovation or landscaping works. These materials may settle within the pipe and gradually create a restriction that becomes worse over time.

Stormwater Drain Blockages

Leaves, soil, roof debris and sediment can affect stormwater drains, grates and downpipe connections. Stormwater drainage problems are often noticed during periods of heavy rain when water cannot move away from the property quickly enough.

 

When to Call a Plumber for a Blocked Drain

Why Does the Same Drain Keep Blocking?

A recurring blocked drain often indicates that the immediate obstruction has been cleared without fully resolving the underlying reason it developed.

Possible causes of recurring drain blockages include:

• Damaged or deteriorated pipework
• Tree root intrusion
• Inadequate drainage fall
• Ongoing disposal of unsuitable material
• A partially cleared obstruction
• A fixture or waste connection that is not performing correctly
• Heavy usage in a commercial, strata or shared environment

If a drain repeatedly blocks, tell the plumber about its history. Information such as how often the blockage occurs, which fixtures are affected and what work has previously been completed can help determine whether a CCTV drain inspection or another form of investigation is appropriate.

Can You Clear a Blocked Drain Yourself?

Minor visible debris may sometimes be removed from an accessible waste grate without dismantling the plumbing. Beyond simple cleaning, care should be taken to avoid causing additional damage or creating a safety risk.

Avoid repeatedly using strong chemical drain cleaners. These products may not reach or remove the actual cause of the blockage, can create a hazard for a plumber who later works on the drain and may affect some types of pipework or fittings.

Do not insert makeshift tools into the drain if they could become stuck or damage the pipework. If wastewater is overflowing, several fixtures are affected or the blockage appears to be within underground drainage, professional assistance is the safer option.

What Should You Do While Waiting for a Plumber?

If you are waiting for a plumber to investigate a blocked drain, reducing further water use can help limit the risk of additional overflow.

• Stop using fixtures that cause the water level to rise
• Keep children, customers and pets away from wastewater
• Do not mix chemical cleaning products
• Move belongings away from the affected area where it is safe to do so
• Take photographs of the overflow or affected fixtures
• Note which fixtures are involved
• Tell the plumber whether the property has experienced similar drainage problems before

If the issue is actively causing property damage and the relevant water supply can be safely isolated, turn it off. Do not enter contaminated areas or attempt to access confined drainage spaces.

When Should You Call a Blocked Drain Plumber?

Professional blocked drain assistance should be arranged when:

• Wastewater is overflowing
• A toilet cannot be used normally
• More than one fixture is affected
• The blockage returns after previous clearing
• There is a strong sewer smell
• An external drain is overflowing
• You suspect tree roots or damaged underground pipework
• Water is pooling around the property during rain
• The drainage issue is disrupting business operations
• You are unsure whether the problem involves sewer or stormwater drainage

Prompt investigation can help reduce the risk of further overflow, hygiene concerns and damage to surrounding areas.

 

Blocked Drain Investigation and Prevention

How Does a Plumber Investigate a Blocked Drain?

A plumber will usually begin by identifying which fixtures are affected, when the drainage problem started and whether the blockage has occurred previously.

Accessible drainage points can then be inspected and an appropriate clearing or testing method selected based on the location and likely cause of the blockage.

Where drainage problems are recurring or damaged pipework is suspected, a CCTV drain inspection may be recommended. A suitable drainage camera can help identify issues such as:

• Foreign objects or internal obstructions
• Tree root intrusion
• Cracked or damaged pipework
• Displaced pipe joints
• Areas of deterioration
• Sections where waste is repeatedly collecting

The findings can then be used to determine whether further drain cleaning, servicing, repair or replacement should be considered.

How to Reduce Future Drain Blockages

Not every drainage problem can be prevented, particularly where underground pipework is damaged, but good plumbing habits can reduce avoidable blockages.

• Keep grease, fats and food waste out of kitchen drains
• Use suitable drain strainers where practical
• Flush only toilet paper and human waste
• Remove accessible hair and debris from bathroom wastes regularly
• Keep external grates clear of leaves, soil and other debris
• Arrange further investigation when the same drain repeatedly slows or blocks
• Keep records of previous drainage repairs and CCTV inspection findings

Recurring drainage problems should not be treated as normal. If the same area continues to block, identifying the underlying cause can help determine whether the drainage system requires more than routine clearing.

Understanding Backflow and Backflow Prevention

What Is Backflow?

Water should normally travel from the water supply network into a property. Backflow occurs when water moves in the opposite direction and flows back towards the clean water supply.

Backflow can generally occur in two ways:

• Back-pressure: Pressure within the property becomes greater than the incoming water supply pressure.
• Back-siphonage: A reduction in supply pressure causes water to be drawn back from the property.

If the downstream water has been exposed to chemicals, waste, irrigation systems, equipment or another potential contamination source, reverse water flow can create a risk to the clean water system.

What Does a Backflow Prevention Device Do?

A backflow prevention device is installed to reduce the risk of contaminated or potentially contaminated water flowing back through a connection and entering the clean water supply.

The type of device required depends on factors such as the identified hazard, plumbing system design and relevant requirements for the property.

Some backflow prevention devices are testable and contain internal components that need to operate correctly to provide the intended protection. A device may be installed but still fail to perform as required if components are damaged, obstructed, worn or deteriorated.

Which Properties May Need Backflow Protection?

Backflow protection may be relevant across a wide range of properties and plumbing systems, including:

• Commercial properties
• Industrial facilities
• Mining and regional sites
• Strata complexes
• Irrigation systems
• Fire services
• Properties using chemicals or specialised equipment
• Sites using non-potable water
• Residential properties with a particular cross-connection risk
• New developments and plumbing upgrades

This is not a definitive compliance list. Backflow requirements should always be confirmed for the specific property, plumbing system and installation.

 

Backflow Testing, Servicing and Property Requirements

What Happens During Backflow Testing?

A licensed plumber or backflow tester will identify the backflow prevention device, review the installation and carry out the applicable test using suitable testing equipment.

A typical backflow testing service may include:

• Confirming the property and device details
• Inspecting accessible parts of the installation
• Isolating the device where required and safe
• Testing the relevant internal functions of the device
• Recording the test result
• Identifying whether servicing, repairs or replacement may be required
• Providing relevant service documentation

The exact testing process will depend on the type of backflow prevention device, the installation and the conditions at the property.

What Can Cause a Backflow Device to Fail a Test?

A backflow prevention device contains components that can deteriorate, become obstructed or be affected by the conditions surrounding the plumbing system.

Possible reasons for a failed backflow test can include:

• Worn internal components
• Debris or scale inside the device
• Damaged seals or springs
• Corrosion
• Long periods without servicing
• Incorrect installation
• Isolation valve problems
• Damage caused by site conditions
• Unauthorised modifications to the plumbing system

A failed backflow test does not automatically mean the entire device needs to be replaced. The tester can assess the condition of the device and determine whether servicing is practical and whether suitable replacement components are available.

How Often Does a Backflow Prevention Device Need Testing?

Backflow testing frequency depends on the device, property and applicable authority or regulatory requirements. One testing schedule should not be assumed to apply to every backflow prevention device.

Property owners and managers should check the documentation associated with the property or confirm the applicable requirements with the relevant authority. Driftline Plumbing Services can also review the available device and property information when arranging a backflow service.

Can a Property Owner Test a Backflow Prevention Device?

Testable backflow prevention devices require suitable equipment, technical knowledge and the relevant licence or accreditation. Property owners should not dismantle, adjust or attempt to test a device themselves.

Property owners and managers can still carry out basic visual observations. Visible leakage, corrosion, damage, restricted access or unauthorised changes to surrounding pipework should be reported to a suitably qualified plumber.

What Backflow Records Should Property Managers Keep?

Maintaining clear backflow records can make ongoing testing and servicing easier, particularly for commercial properties, strata complexes and sites with multiple devices.

Useful backflow records may include:

• Property address
• Device location
• Device type and identification details
• Installation date, if known
• Previous backflow test reports
• Servicing and repair history
• Photographs of the device and installation
• Relevant authority correspondence
• Site access instructions
• Contact details for the responsible property representative

For properties with several backflow prevention devices, maintaining a device register can help reduce missed testing or servicing requirements and make it easier to compare previous results.

 

Backflow Installation, Planning and Professional Services

Backflow Planning for New Plumbing Projects

Backflow requirements are best considered during the plumbing design and planning stage rather than being addressed after other building elements have already been installed.

Early planning can help account for:

• Appropriate backflow device selection
• Accessible installation locations
• Isolation requirements
• Drainage for device discharge where relevant
• Protection from physical damage
• Future testing and maintenance access
• Coordination with landscaping, walls, cabinetry and equipment
• Documentation and project handover requirements

Where backflow protection is considered too late in a project, the remaining installation location may be less practical, harder to access or more difficult to coordinate with surrounding building elements.

Why Use a Licensed Backflow Testing Service?

Using a suitably licensed backflow service provides a clear record of the condition and test result of the device while ensuring any recommendations are based on the actual installation.

Driftline Plumbing Services holds backflow licence BF5553 and provides backflow testing, servicing and installation across Perth and Western Australia.
