Conducting Regular Visual Inspections

It is essential to Visually check your hot water heater biannually for wear, corrosion, and potential hazards. This proactive approach will help ensure the following:

• Checking around your water heater’s bottom tank for signs of rust or small leaks
• Assessing water pipes and fittings for corrosion
• Always make sure electrical cables and connections are in good condition with no exposed wires
• Maintain safe water temperatures and distance the system from any flammable materials.
• Looking for unusual noises, vibrations or abnormalities when the system is operating

Check for fluctuating temperatures which may suggest inconsistent pressure, and verify adequate hot water supply flow rates. Observe the burner flame if applicable. Any changes could be a sign your heater requires maintenance.

Document your preventive maintenance changes since the last inspection. Subtle issues caught early can help save time and money by preventing more serious problems down the track. If in doubt, contact our experts to address your plumbing maintenance concerns and diagnose potential faults.

Checking for Leaks

Regularly examining your plumbing for leaks can prevent significant damage by catching issues early. Follow these key steps to inspect your hot water system for corrosion:

1. Disconnect the water supply and power before inspection.
2. Check out your water heater base for pooling water or rust stains.
3. Inspect all pipes, valve fittings, pressure relief valve and connections for signs of moisture or corrosion.
4. After wiping fittings dry, restore water and check for any dripping.
5. With the power still off, After turning the power off, run a hot tap; any flowing water suggests a leak.
6. Also check cold taps to isolate if it’s a hot water specific issue.
7. If you detect any small leaks, document them and contact our office to have a professional flush out the problem.

Minor leaks can escalate to systemic issues, making it wise to consult a licensed plumber. Early detection can help prevent the need for emergency repairs down the track. Our licenced service providers have the expertise for plumbing repairs to diagnose and rectify any hot water system leaks.

Inspecting for Rust and Corrosion

Rust and corrosion are common issues that can severely impact the lifespan of your hot water system. Regularly inspect pipes, tank exterior, valves, and anode rod for visible signs of wear.

Be vigilant for rust, pitting, flakes, discolouration, and scale build-up as indicators of wear and corrosion. The sacrificial anode rod helps protect your water system, and should be replaced every 1-2 years as it corrodes over time.

1. Examine the water heater’s exterior and base for rust spots or stains.
2. Check all valves and pipe fittings for corrosion and leaks.
3. Remove and examine the anode rod - replace if heavily corroded.
4. Contact a plumber if you find External corrosion for tank repairs.

Addressing corrosion early can significantly prolong your water heater’s lifespan. For experienced assistance inspecting or replacing your anode rod, contact our team today.

Testing Water Pressure

Maintaining the correct water pressure is crucial for the performance and lifespan of your hot water system. Maintain water pressure within the recommended range of 50-80 PSI. Excess pressure puts strain on components leading to premature wear while low pressure causes flow problems.

To test your water pressure:

1. Find the cold water inlet pipe within your water heater to prevent sediment accumulation.
2. Fix a water pressure gauge onto the supply line.
3. Turn on the nearby cold water faucets.
4. Check the pressure reading after letting it stabilise - ideal is 65 PSI.
5. If the pressure is outside the recommended 50-80 PSI range, install a pressure limiting valve to regulate it.

Regular testing and proactive measures in line with preventive maintenance standards can extend your system’s life. Our team can install pressure regulation solutions perfectly suited to your system requirements.

The Importance of Flushing the Water Heater

Flushing tank is essential to fully utilise water heater capacity and maintain peak energy efficiency. Over time, hard water minerals from Blacktown’s water supply can accumulate at the bottom of the tank in the form of scale and debris.

To flush water and prevent issues like:

• Noisy heating elements
• Longer heating times
• Rumbling and banging noises
• Thermostat failure
• Corrosion damage

Include regular water heater maintenance steps here on how to proceed with flushing the tank of your heater:

1. Switch off the power and water supply lines to the tank.
2. Connect a hose to the drain valve to empty water from the bottom of the tank.
3. Open the drain valve and allow water to flow out clearing the drain lines into a bucket or drain area.
4. Keep flushing until the water runs clear, indicating no sediment remains.
5. Close drain valve, refill tank, restore power and water supply.

An annual flush of the tank conducted each year can help reduce mineral buildup as part of your water heater maintenance. Get in touch with our experts for hot water system maintenance assistance.

Draining and Removing Sediment

Sediment, including mineral deposits and rust, tend to collect at the bottom of your hot water system’s tank over time. Draining water from the tank helps remove this sediment buildup.

Follow these steps to drain your tank:

1. Shut down the power to your hot water system.
2. Connect a garden hose to the drain valve at the tank’s base.
3. Place the hose end in a bucket or outdoor area for drainage.
4. Gradually open the drain valve to start water flow through to the drain.
5. Allow the tank to drain completely until the water runs clear.
6. Close the drain valve once finished and disconnect the hose.

Carrying out your water heater maintenance by draining and flushing your tank annually removes sediment. Contact our team if you need help with maintenance.

Inspecting and Replacing the Anode Rod

The anode rod is a crucial component that protects your hot water system from corrosion. Made from reactive metals like aluminium and magnesium, the rod attracts corrosion instead of allowing the tank to be damaged.

Inspect anode rods approximately every two years to confirm functionality. Over time it will become eroded and need replacing. A corroded rod cannot properly protect the tank, which can shorten its lifespan.

Here is how to inspect and replace your anode rod if required:

1. Turn off power and water supply, and open a hot tap to depressurise the tank.
2. Remove the anode rod at the top of the tank using the correct socket wrench.
3. Examine the rod – replace it if more than 6mm of the diameter is eroded, as this will extend the heater’s lifespan.
4. Clean threads and apply tape/sealant to new anode rod.
5. Reinstall tightly. Restore water supply and power. Check for leaks.

Replacing a highly corroded anode rod can extend its lifespan and ensure your water heater operates optimally for longer. Contact our team if you need assistance with inspecting or changing your unit’s sacrificial anode rod.

Testing the T&P Valve

The temperature and pressure (T&P) relief valve is a crucial safety device to use in water heater maintenance on your heater. It helps prevent explosion risks by releasing excess pressure and heat if the tank overheats or water pressure becomes too high.

You should test the T&P valve every 6 months as part of your maintenance routine. Another important aspect of maintenance, here is how to safely test it:

1. Locate the T&P valve on the side of the hot water tank.
2. Attach a short discharge pipe if not already connected.
3. Lift or press the lever gently until water starts flowing out.
4. Check the valve closes properly when released.
5. Inspect discharged water for signs of sediment or corrosion flakes.
6. Check valve rating matches your tank’s temperature and pressure.

Water release or a failure to seal from the T&P valve indicates a need for attention. Contact our office if you have any issues testing or need a faulty T&P valve replaced.
