A reliable hot water system is essential for every Melbourne household, especially during the winter months. Yet, when something goes wrong, it can quickly disrupt daily routines. From fluctuating water temperatures to leaks, water heater issues are common, but one problem stands out more than others.
This blog highlights the most common water heater problems, the signs to look out for, and when to call a local plumber in Melbourne for expert hot water plumbing assistance.
Why Leaks Are The Most Common Water Heater Problems?
Among all possible issues, a leaking water heater is by far the most frequent and concerning problem homeowners or building owners face. Whether it’s a leaking hot water tank, a water heater leaking from the bottom, or minor drips around fittings, leaks can indicate internal damage, corrosion, or excessive pressure inside the tank.
Even a small leak can cause significant water damage if ignored, leading to higher repair costs and potentially necessitating the replacement of the entire system.
What are the Causes of Water Heater Leaks
Leaks in water heaters can happen for several reasons, often linked to the unit’s age, the materials used in its construction, and the maintenance it has received. Some of the most common causes of water heater leaks, and the situations that may require services for hot water plumbing in Melbourne, include:
1. No Hot Water
A lack of hot water can stem from issues like a tripped circuit breaker, a faulty thermostat, or a malfunctioning heating element. For gas heaters, problems with the pilot light or thermocouple are common culprits. To address this, check the power supply and reset any tripped breakers. If the problem persists, inspecting and possibly replacing the heating element or thermostat may be necessary.
2. Leaking Water Heater
Leaks often result from corrosion, loose connections, or damaged valves. If you notice water pooling around the base of the heater, inspect the inlet and outlet connections for tightness. A leaking tank typically indicates severe corrosion and may require a full replacement.
3. Strange Noises
Noises such as popping or rumbling are common hot water heater problems, often indicating sediment buildup at the bottom of the tank. This sediment can overheat, causing the water to boil and produce noise. Flushing the tank annually can help remove sediment and prevent these issues.
4. Discoloured or Smelly Water
Brown or yellow water indicates rust inside the tank, while a rotten egg smell typically indicates bacterial growth. In both cases, replacing the anode rod can help. If the issue persists, it may be necessary to flush the tank or consult a professional.
5. Low Water Pressure
Reduced water pressure from hot water taps can result from sediment buildup or mineral deposits in the tank. Flushing the tank can alleviate this issue. Additionally, inspecting and cleaning aerators and showerheads can improve water flow.
What to Do If the Water Heater Is Leaking?
If you discover a hot water leak or notice the water heater leaking from the bottom, here’s what you should do immediately:
-
Turn Off the Power Supply
-
For electric heaters, switch off the circuit breaker.
-
For gas heaters, turn the gas valve to “off.”
-
Shut Off the Water Supply
Locate the cold-water shutoff valve on top of the heater and close it to prevent more water from entering the tank.
-
Drain the Tank (If Safe)
If the leak is severe, draining the tank can minimise water damage. Use a hose to direct the water into a drain or outside area.
-
Call a Professional Plumber
A qualified hot water plumber in Melbourne can assess whether the heater can be repaired or if a replacement is necessary. Never attempt complex repairs without professional guidance.
When to Fix or Replace Your Hot Water System?
The best course of action ultimately depends on the extent of the damage and the age of your system. This assessment is especially important in cases of a hot water heater leaking from the bottom, and can be evaluated by considering the following scenarios:
-
A small leak near the fittings: This may be fixed by simply tightening the fittings or replacing them.
-
A leak from the base of the tank: Generally, tanks require replacement, as internal corrosion is irreparable.
-
A system that has consistent issues or is older (8 years): Unless the system is "high-end", it is worth simply replacing it. You will ultimately save on repairs!
A local plumbing company offering commercial and residential plumbing services in Melbourne will assess your system and provide recommendations based on the condition of your current unit.
How to Prevent Future Hot Water Problems?
To reduce the risk of leaks and extend the life of your hot water heating and plumbing system, perform regular maintenance. A few means to prevent issues are through regular:
1. Flushing the Tank Annually
This prevents sediment from building up in the water tank during operation, which causes overheating and tank corrosion.
2. Checking the Anode Rod
The anode rod protects the interior shell of the tank by attracting corrosive minerals during operation. The better you maintain the anode rod (replace every 2-3 years), the better it protects your water tank.
3. Check the TPR valve
Confirm that the TPR valve flushes excess pressure during operation.
4. Schedule Regular Plumbing Maintenance
Plumbing companies can identify minor issues before they escalate into more extensive repairs or replacements. Think of this as a general condition check-up on the long-term effectiveness of your system. Scheduling regular hot water plumbing maintenance will ensure your system is operating in good order year-round and avoid water heater tank leaks.
