A cold shower in the morning or an unexpectedly high utility bill are more than just a nuisance; they’re often the first sign of a failing hot water system. Whether you have a traditional storage tank or a modern tankless unit, it’s crucial to understand the warning signs and know when to call a professional.
In this comprehensive guide, we’ll help you diagnose common hot water system problems, offer a few simple troubleshooting tips, and provide professional advice on when to repair or replace your unit.
5 Signs of a Failing Hot Water System
Your hot water unit could be in need of repairs or a replacement if you experience any of the following:
- No Hot Water: This is the most obvious red flag. If your tap runs cold despite the system being on, it could be a sign of a faulty thermostat, a tripped circuit breaker (for electric units), a pilot light that has gone out (for gas units), or a major internal issue.
- Strange Noises: Don’t ignore rumbles, pops, or bangs coming from your unit. These sounds often indicate a build-up of sediment inside the hot water tank. Over time, this sediment can cause damage, reduce efficiency, and shorten the lifespan of your unit.
- Visible Leaks: Any pool of water or dripping from your hot water system is a serious problem. If you see a leak from the base of the unit, this usually indicates a burst hot water tank, which requires immediate replacement. For leaks from other connections, it’s best to call a plumber immediately.
- Discoloured or Smelly Water: If the hot water coming from your taps is rusty, discoloured, or has a metallic smell, it could mean there is rust inside your hot water tank. This is a clear sign that the tank is corroding and may be close to failing.
- Running Out of Hot Water Quickly: If you find yourself running out of hot water much faster than usual, your system may be losing efficiency due to sediment buildup or may be improperly sized for your home.
Troubleshooting Before You Call a Professional
Before you call in the experts, these quick checks can help you identify the source of the problem.
- Check the Power: For an electric hot water system, check your circuit breaker to see if it has been tripped. For a gas unit, check if the pilot light has gone out.
- Check the Water Temperature: If you are only getting lukewarm water in the shower, the problem could be a faulty temperature control valve.
- Look for Leaks: Check all the visible pipes and connections for signs of dripping water. If you notice a constant leak from the pressure relief valve (PTR valve) pipe, the valve needs to be replaced. Manufacturers recommend replacing this valve every five years.
When to Repair vs. When to Replace
Deciding between repairing and replacing your hot water system can be a tough choice. Here’s our professional advice to help you make the right investment for your home:
- Age is a Factor: A hot water system that is over 15 years old with signs of extensive corrosion is likely at the end of its life. While a quick fix might get it working, replacing it is often a better long-term investment.
- Frequent Repairs: If you find yourself calling a plumber to fix your unit repeatedly, the cost of ongoing repairs will quickly add up. A new, more efficient system will save you money and headaches in the long run.
- Energy Efficiency: A modern hot water unit is significantly more energy-efficient than an older one. Replacing an old unit can lead to substantial savings on your energy bills.
Always hire a licensed plumber for any repairs or new installation. This is important to ensure your hot water unit is fitted correctly, safely, and in line with all Australian standards.
