Hot water is something we often take for granted, and as a result, hot water systems often go unnoticed until something goes wrong, forcing you to consider whether you need replacement or repair. Most hot water systems last longer than a decade, and if you know what to look for, you can catch any potential issues before they become detrimental. It’s always best to be prepared. By knowing the warning signs of your hot water system failing, you’ll have time to research and ensure your next hot water system is the best size for your household and daily water usage.
A hot water system failure can often be a blessing in disguise, especially if your system is over ten years old. The world of hot water system technology moves quickly, and there’s a good chance that your system isn’t as efficient as some newer models. This means you may need to consider replacing your hot water system.
So, what are the signs that your hot water system is beginning to fail? Is it time to invest in a more modern model, or is it better to hire someone to repair your water system? Read on for more information.
Nobody enjoys stepping into a shower and waiting for the water to warm up, only to realise it’s not going to. Keep an eye out for the following warning signs so you don’t find yourself shivering.
Is the water coming from your hot tap a different shade from that of your cold tap? This could indicate a problem, particularly if you have a storage tank that uses sacrificial anodes. These anodes should be replaced every 5 years or so by a professional plumber, and if they aren’t replaced when worn out, rust and deterioration from your tank can find their way into your water.
At this point, you’ll need to replace your hot water system as soon as possible.
Like any appliance, your hot water system has an expiry date. Knowing the make, model, and type of your hot water heater will give you a good indication of when to start budgeting for a new one. More so, this can tell you whether a replacement is necessary or if it’s worth addressing any concerns to extend the life of your current hot water system.
Generally speaking, your hot water heater should not make noise. A low hum is okay, or even some sounds when kicking off on a cold evening. However, continuous hissing, knocking, squealing, banging or hammering can be a sign that your water heater is in serious trouble. The problem can be caused by water hammer in your pipes, deterioration in your tank, or even a loose gas fitting, so getting a professional out to take a look urgently is the best course of action.
Not all leaks are scary, nor are they equal. Some leaks, such as those released from the Tempering Pressure Relief Valve, are normal and a sign that things are working as they should. On the other hand, if your system is leaking in bursts, boiling water, or leaking from the connections and pipes, you may have a larger issue on your hands.
An inconsistent water temperature is one of the most obvious signs that your hot water system is on its way out. If it’s hot one minute and freezing the next, or if you need to reset the thermostat frequently, there could be something wrong with your heating element or a range of other components. Unfortunately, if you let this issue sit for too long, you will likely be up for a replacement rather than a repair.
This is one for the gas systems. A rotten egg smell emanating from your hot water system is a huge warning sign that something is awry. A gas leak can be dangerous and expensive, and if you suspect your hot water system is the source of the stink, a call to a plumber or gas fitter is essential.
Another nod to gas systems: a yellow pilot light flame is a sign that it is not receiving enough oxygen to combust properly. This is one of the most urgent signs that something is seriously wrong with your gas hot water system, as it can mean carbon monoxide is being released into the air. This can result in carbon monoxide poisoning, which can have catastrophic results.
As you can tell, some warning signs about your hot water system are more urgent than others. Ultimately, you should budget for a new hot water system every decade or so, with regular repairs and maintenance in the meantime. Any hot water system issues should be addressed quickly, ideally by a professional, as problems can escalate quickly if left to chance.
A broken hot water heater or system can provide a great opportunity to make your water use more efficient, reliable, and affordable, especially if your family has grown since the original system was installed. Consider the size and type of system that will best suit your home and lifestyle. Perhaps you can switch to gas or solar to reduce your outgoings and help protect the planet, or maybe you need a larger-capacity tank to support your growing family.
