If you rely on a hot water system, you know how important your storage tank is. It stores the hot water you need every day, whether at home or in your business. But like any part of your plumbing, storage tanks can run into problems that affect performance and comfort. At All Needs Plumbing, we’ve seen it all, and we’re here to help you spot common storage tank issues and fix them fast—so you don’t have to go without hot water.
Common Storage Tank Issues
Water Heater Not Heating Properly
When your water heater isn’t heating properly, it can be frustrating and inconvenient. You might notice lukewarm water or water that never quite reaches the temperature you set on the thermostat. Most often, this happens because the heating element has burned out or the thermostat is faulty. Sometimes, the problem lies with the power supply—whether it’s an electrical fault or a tripped breaker.
Heating elements and thermostats wear out over time, especially in hard water areas where mineral deposits can cause damage. Instead of trying to fix this yourself, which can be risky, call us. We’ll test your system with professional equipment, identify the faulty parts, and replace them safely and efficiently. This way, you get your hot water back without fuss or delay.
Sediment Buildup and Noise Issues
If your hot water tank starts making strange noises like popping, rumbling, or creaking, sediment buildup is usually the cause. Over time, minerals from your water settle at the bottom of the tank. When the heating element heats the water, the sediment traps steam bubbles that pop and make noise.
This buildup also reduces the efficiency of your heater because it acts as an insulator, making your system work harder and use more energy. Left unchecked, sediment can cause damage to the tank’s bottom, leading to leaks or even tank failure. Flushing your tank once a year is a simple way to prevent this. Flushing means draining the tank to remove sediment and then refilling it with fresh water. Pro-Tip: Plan your flush during warmer months when you can go without hot water for a short time. This maintenance step can save you money in the long run by improving efficiency and extending your tank’s life.
Leaking Water Heater Tank
Leaks around your water heater tank are a serious warning sign. Common causes include a faulty pressure relief valve, a loose or damaged drain valve, cracks caused by sediment buildup, or corrosion when the anode rod wears out. The pressure relief valve releases excess pressure to keep your tank safe, but if it fails, it can leak water. Drain valves can loosen over time or get damaged during maintenance. Sediment buildup can cause cracks or corrosion, especially if the anode rod—which protects the tank from rust—has deteriorated.
If you notice water pooling or dripping near your tank, don’t ignore it. Leaks can cause water damage to your property and indicate your tank may be close to failure. We recommend calling a professional immediately. We’ll inspect your tank, locate the leak source, and repair or replace the faulty parts.
Pro-Tip: Regularly check your pressure relief valve by lifting the lever to make sure it’s working properly and replace the anode rod every few years to prevent corrosion and extend your tank’s life.
Discoloured or Cloudy Water
Rusty, cloudy, or smelly hot water is a sign that something’s wrong inside your tank or pipes. Rusty water usually means corrosion inside the tank or your plumbing, while cloudiness can indicate sediment or bacterial growth. Both issues affect water quality and safety.
Flushing the tank can often clear out sediment and improve water clarity. If corrosion is severe, it might be time to replace your tank to ensure your water stays clean and safe. We’ll inspect your system and advise the best course of action.
Pressure Relief Valve Issues
The pressure relief valve is a critical safety feature on your hot water system. It prevents dangerous pressure buildup inside the tank by releasing water when pressure gets too high. If the valve leaks or makes noise, it may be faulty or stuck. A malfunctioning valve can cause pressure to build dangerously, risking tank rupture or damage. We test these valves regularly during inspections and replace them when needed to keep your system safe and reliable.
Preventive Maintenance Tips
Taking care of your storage tank with regular maintenance can save you from costly repairs and unexpected breakdowns. Here are some essential tips to keep your hot water system in top shape:
1. Flush your tank annually to remove sediment buildup. This simple step improves efficiency, reduces noise, and prevents damage.
2. Inspect and replace the anode rod every 3-5 years. The anode rod protects your tank from rust by attracting corrosive elements. When it wears out, your tank becomes vulnerable.
3. Check the pressure relief valve regularly. Lift the valve’s lever to ensure it opens and closes smoothly. If it leaks or sticks, call us for a replacement.
4. Watch for leaks and unusual noises. If you notice anything odd, don’t wait—call a professional. Early detection can prevent bigger problems.
5. Consider installing a whole-house water filtration system. Filtering your water reduces minerals and sediment entering your tank, prolonging its life and improving water quality.
When to Call a Professional
While some maintenance tasks are straightforward, many hot water system issues require professional expertise. If you notice persistent leaks, strange noises, or your water isn’t heating properly despite your efforts, it’s time to call All Needs Plumbing.
Handling electrical or gas components without proper training is dangerous and can cause more harm than good. We provide expert inspections, repairs, and replacements tailored to your system, ensuring safety, efficiency, and peace of mind.
FAQs About Storage Tank Issues
Do solar hot water heaters work in winter?
Yes, solar water heaters still work in winter, but their efficiency drops due to less sunlight. Most systems include backup heating to cover colder days and ensure you always have hot water.
How long does water stay hot in a solar water heater?
With good insulation, water can stay hot for 24 to 72 hours depending on the tank size, insulation quality, and starting temperature.
What is the best place to keep a solar water heater?
The best spot is a roof or area with full sun exposure throughout the day. In Australia, solar collectors should face north and be tilted to match your latitude for maximum heat absorption.
Does a solar water heater work in the rainy season?
Solar water heaters can still operate during rainy seasons but rely more on backup heaters when sunlight is limited.
Does a solar water heater work at night?
Solar water heaters don’t generate heat at night but store hot water collected during the day. Backup heating systems ensure hot water availability during night or cloudy weather.
