Safety Checks and Component Maintenance

Safety must be the primary concern when conducting any maintenance on your hot water system, in line with our experts’ detailed safety guidelines. Our safety measures recommend waiting for the system to cool down should it have been used recently.

Always turn off the power and shut off the water supply before beginning. Ensure proper ventilation when dealing with gas systems.

Routinely checking and testing components is crucial to ensure the safe and efficient operation of water heating systems:

• Testing pressure relief valves, or TPR valves, yearly by opening them for 5-10 seconds is crucial to ensure they’re not stuck shut. Replace if over 10 years old.
• Level switches: Test function by manually activating the switch. Replace if faulty.
• Sensors: Check sensors are clean and connections are intact. Faulty sensors can prevent heating operation.
• Pipe connections: Inspect for leaks indicating loose fittings. Tighten or replace corroded pipes.
• Insulation: Ensure adequate insulation on hot water lines and storage tanks to maximise efficiency.

Essential hot water system components like heating elements, circulation pumps, and anode rods also require a professional service every five years:

• Heating elements: Descale or replace those over 8-10 years to sustain optimum heating.
• Circulation pumps: Lubricate or replace pumps over 5 years old to sustain good flow.
• Anode rods: Sacrificial anode rods should be inspected and replaced every five years in metal tanks to prevent corrosion.

Flushing the System

Conduct an annual flush to prevent sediment and scale from restricting flow and shortening your hot water tank’s lifespan by following these steps:

1. Turn off power and water supply, and activate the drain valve to release pressure.
2. Connect a garden hose to the drain valve and place the other end in a suitable drainage area.
3. open the pressure relief valve and all hot taps, allowing cold water and air in, which facilitates draining the tank of any sediments in the area around it.
4. Once water runs clear with no sediment, close all taps and the water tank valves. Refill the system and restore power.

Flushing particulates from your system can improve its lifespan, water quality, and performance. It improves heating efficiency, can resolve pressure or flow issues, and prolongs component lifespan by preventing internal scale buildup and corrosion.

For complete servicing and optimal maintenance of your water supply, our licensed plumbers provide professional flushing and servicing. We use high-velocity flushing to ensure optimal clearing of sediment, providing the best protection and performance.

Testing Relief Valves

Pressure and temperature relief valves are vital for safety and component longevity within your water system. Test the pressure relief valve which should be maintained annually by following these steps:

1. Locate the TPR valve on the top of your water heater or along the first metre of the outlet pipe.
2. Carefully lift and release the lever, allowing water to flow for 5-10 seconds before closing.
3. Check the drainage area for obstructions before testing. The valve should discharge around 20 litres per minute.
4. Replace the entire valve if it fails the test or if over 10 years old as sticky valves can fail dangerously.

Testing confirms that the valve opens correctly under pressure, safely releasing excess hot water, thus reducing explosion risks and increasing the unit’s lifespan. If water does not flow freely, contact our licenced plumbers to repair or replace the valve.

The expansion control valve should be checked while servicing the system. Our experts examine valves during maintenance calls, ensuring ongoing safety and compliance.

Replacing Anodes and Heating Elements

It’s crucial to ensure you periodically replace the sacrificial anode rod and heating element to enhance the lifespan of your hot water system’s storage tank. The anode rod is a consumable metal that corrodes to prevent corrosion damage to the tank itself. Most anodes, crucial for the lifespan of hot water tanks, need replacing every 5-8 years.

As it corrodes over time, the anode rod’s protective effect diminishes. Replacing it on schedule helps avoid sediment buildup and rust corrosion inside the tank which can shorten its lifespan. Heating elements also degrade, losing heating efficiency after 8-10 years.

Signs it’s time to replace anodes or elements include:

• Reduced hot water flow or temperature
• Noisy rumbling or banging inside the tank
• Pool of water under tank indicating a leak

During your hot water service, our licensed plumbers inspect anodes and elements, providing essential maintenance to ensure every 3-5 years. We can test heating efficiency and advise when replacement is optimal for your system.
