What To Do When Your Water Heater Starts Leaking From the Top

Discovering a water heater leak can be alarming, especially if it’s coming from the top of the unit. While leaks might seem like a minor issue, they can lead to significant problems, including damage to surrounding areas and increased utility bills. If not addressed promptly, the leak could result in costly repairs or even require a complete replacement of the water heater. In some cases, you may need the assistance of a water damage restoration service in Johnstown to manage the aftermath.

Why Is My Water Heater Leaking From the Top?

Water heater leaks from the top are typically caused by a few common issues:
Loose or Faulty Connections
The pipes or fittings connecting to the water heater may be loose or improperly sealed, causing water to leak. This is one of the most straightforward problems to fix.
Corroded Inlet or Outlet Valves
Over time, the valves at the top of your water heater, where cold water enters and hot water exits, can corrode and develop leaks. Corrosion can compromise the integrity of the components, leading to water seepage.
Pressure Relief Valve Issues
The temperature and pressure relief (T&P) valve is a safety feature designed to release excess pressure from the tank. If this valve malfunctions or is improperly installed, it can leak.
Internal Tank Damage
In rare cases, a leak at the top of the water heater may indicate internal tank damage. This usually requires professional assessment and potentially replacing the entire unit.

Steps to Take When You Notice a Leak

If you discover your water heater leaking from the top, follow these steps to minimize damage and address the issue promptly:
1. Turn Off the Power Supply
Electric Water Heaters: Locate the circuit breaker that supplies power to the water heater and turn it off. This prevents the risk of electrical shock.
Gas Water Heaters: Set the gas control valve to the “off” position to ensure safety while inspecting or repairing the unit.
2. Shut Off the Water Supply
Find the water shut-off valve located near the top of the water heater. Turn it clockwise to stop the flow of water into the unit. This step helps prevent further leakage and water damage.
3. Identify the Source of the Leak
Carefully inspect the top of the water heater to determine where the water is coming from. Common areas to check include:
The inlet and outlet connections
The T&P valve
Any visible cracks or damage to the tank
4. Tighten Connections
If the leak is due to loose connections, use a wrench to tighten the fittings gently. Be careful not to overtighten, as this can cause further damage.
5. Replace Faulty Components
If you identify a corroded valve or a malfunctioning T&P valve as the cause of the leak, these parts may need to be replaced. Turn off the water supply completely, drain the tank partially, and replace the damaged components with new ones.
6. Dry the Area
After addressing the leak, dry the area thoroughly to prevent mold or mildew growth. If water has already seeped into surrounding floors or walls, consider contacting a water damage restoration service in Johnstown to assess and repair any damage.

When to Call a Professional

While minor leaks can often be resolved with basic tools and DIY know-how, some situations require professional intervention:
Persistent Leaks: If the leak continues despite your efforts to fix it, the problem may be more serious than it appears.
Tank Damage: If the internal tank is compromised, you will likely need a replacement water heater.
Extensive Water Damage: If the leak has caused significant damage to floors, walls, or nearby areas, a water damage restoration service in Johnstown can help mitigate the effects and restore your home.
Preventing Future Water Heater Leaks
Regular maintenance is key to preventing leaks and prolonging the life of your water heater. Here are some tips:
Inspect Connections and Valves: Periodically check for signs of corrosion or looseness in the fittings and valves.
Flush the Tank Annually: Sediment buildup can damage the tank over time. Flushing the tank removes these deposits and helps maintain efficiency.
Replace Old Components: If you notice signs of wear on valves or fittings, replace them promptly to avoid leaks.
Monitor Water Pressure: High water pressure can stress your plumbing system and water heater. Install a pressure regulator if needed.
