Ultimate Guide to Water Heater Maintenance by Redland City Plumbing

A reliable hot water system is essential for the comfort of any home. Whether it’s for a morning shower, washing dishes, or running the laundry, a water heater plays a crucial role in your daily life. However, like any other appliance, water heaters require regular maintenance to keep them functioning efficiently and avoid costly repairs or replacements.

In this Ultimate Guide to Water Heater Maintenance, brought to you by Redland City Plumbing, we’ll explore everything you need to know about maintaining your water heater to ensure it continues to deliver hot water reliably. From routine checks to common problems and tips for extending the life of your water heater, this guide has you covered.

Why is Water Heater Maintenance Important?

Water heaters, whether gas or electric, operate under constant pressure and heat. Over time, sediment can build up, components can wear out, and the system may become less efficient. Proper maintenance ensures your water heater works at its best, preventing unexpected breakdowns, improving energy efficiency, and extending the lifespan of the appliance.

Signs That Your Water Heater Needs Maintenance

Before diving into maintenance steps, it’s important to know when your water heater requires attention. Look out for the following signs:

• Inconsistent water temperature: If your water temperature fluctuates or you’re getting cold water when you expect hot, your heater might need a checkup.

• Strange noises: Rumbling, popping, or cracking sounds can indicate sediment buildup inside the tank.

• Leaks around the water heater: Puddles or damp spots near the base of the heater suggest a potential leak that could lead to further damage.

• Rusty or discoloured water: If your hot water turns rusty, this can be a sign of corrosion in the tank or pipes.

• Increased energy bills: A sudden increase in your energy consumption could mean your water heater is working harder than necessary due to inefficiency.

How to Maintain Your Water Heater: Step-by-Step Guide

Proper water heater maintenance should be carried out at least once a year to keep everything running smoothly. The following steps are designed to help you maintain your water heater, whether it’s electric or gas-powered.

1. Check the Temperature Setting

One of the simplest maintenance tasks you can do is ensure the temperature setting on your water heater is correct. Most experts recommend setting the thermostat to around 50°C to 60°C. This is warm enough for most household tasks but low enough to prevent energy wastage and scalding risks.

• How to Adjust:

  • For electric water heaters: Locate the thermostat panel and adjust the temperature dial.

  • For gas water heaters: Turn the temperature control dial to your preferred setting.

Keeping the temperature too high can waste energy, while too low a setting can result in inadequate hot water.

2. Inspect the Anode Rod

The anode rod is a crucial component that helps prevent your water heater from rusting. It works by attracting corrosive elements in the water, preventing them from attacking the tank’s interior. Over time, the rod corrodes, and it needs to be replaced to continue protecting your water heater.

• How to Inspect:

  • For electric water heaters, remove the access panel to locate the anode rod.

  • For gas water heaters, remove the top panel or insulation to access the rod.

If the anode rod is worn down to less than 30% of its original size, it should be replaced. You can buy replacement rods at most hardware stores or contact Redland City Plumbing for expert advice and replacement.

3. Flush the Tank to Remove Sediment Buildup

Sediment from hard water can accumulate at the bottom of the tank, leading to inefficiency and strange noises. Flushing your water heater removes sediment and improves the efficiency of the heating element.

• How to Flush the Tank:

  1. Turn off the power supply to the water heater. For electric models, switch off the circuit breaker. For gas models, turn off the gas supply.

  2. Turn off the water supply to the heater.

  3. Connect a hose to the drain valve at the bottom of the tank and place the other end in a bucket or drainage area.

  4. Open the drain valve and allow the water to flow out until it runs clear.

  5. Close the drain valve, remove the hose, and turn the water supply back on.

  6. Restore power or gas to the unit.

Flushing the tank should be done once a year to prevent sediment buildup and ensure your water heater runs efficiently.

4. Check the Water Heater’s Vent (for Gas Heaters)

For gas water heaters, the venting system ensures that harmful gases, such as carbon monoxide, are safely expelled from your home. Over time, the vent can become clogged with debris or bird nests, posing a serious safety risk.

• How to Inspect the Vent:

  1. Check the vent cap for any obstructions or blockages.

  2. Ensure the vent is free of debris, and clear away anything that may prevent proper ventilation.

If you’re unsure how to inspect or clean the vent, it’s always best to call in a professional like Redland City Plumbing to ensure it’s done correctly.

5. Test the Pressure Relief Valve

The temperature and pressure relief (T&P) valve is a safety feature that prevents the tank from building up excessive pressure, which can cause the tank to rupture. Over time, this valve can become stuck or malfunction.

• How to Test the T&P Valve:

  1. Lift the valve’s lever to let a small amount of water flow from the discharge pipe.

  2. If the valve doesn’t release water or seems stuck, it may need to be replaced.

Testing the T&P valve every six months ensures your water heater is functioning safely.

6. Insulate Your Water Heater

To improve energy efficiency and reduce heating costs, consider insulating your water heater. Insulating the tank helps keep the water hot for longer periods, reducing the need for frequent heating cycles.

• How to Insulate:

  • You can purchase an insulation jacket or blanket specifically designed for water heaters.

  • Simply wrap the insulation around the tank, ensuring the thermostat and burner area are not covered.

Be sure to follow the manufacturer’s instructions when insulating your heater, especially if it’s a gas model, to avoid any safety hazards.

7. Check for Leaks

Leaks can happen around the tank, pipes, or fittings, and they should be addressed immediately to prevent water damage. Inspect the water heater and surrounding area for signs of dampness, corrosion, or water pooling around the base.

• How to Check for Leaks:

  • Examine the tank for any visible cracks or leaks.

  • Check the pipe fittings and connections for any signs of drips or wetness.

If you notice any leaks, it’s important to call a professional plumber to assess the situation and perform the necessary repairs.

How Often Should You Perform Maintenance on Your Water Heater?

Regular maintenance should be performed once a year, but if you live in an area with hard water, you may need to flush the tank more frequently (every 6 months). Additionally, some components, such as the anode rod, may need to be replaced every 3–5 years, depending on water quality and usage.

When to Call a Professional

While regular maintenance is something you can perform yourself, certain issues require professional expertise. If you notice any of the following, it’s best to contact Redland City Plumbing for assistance:

• Water heater is not producing hot water

• Strange noises persist after flushing the tank

• The T&P valve isn’t working properly

• Persistent leaks that you can’t identify or fix
