A leaking water heater can be a serious issue, as it may lead to water damage, decreased efficiency, or even a complete breakdown of the unit.
However, while a permanent solution will require professional repair or replacement, there are several steps you can take to manage the situation and minimize damage until help arrives temporarily.

Temporary Fix for Leaking Hot Water Heater
Here’s how you can temporarily fix a leaking water heater:
Step 1: Ensure Your Safety First
Your safety should be your top priority when dealing with a leaking water heater. Depending on whether your water heater is powered by electricity or gas, you’ll need to take different precautions.
You can start by turning off the power supply to the water heater at the circuit breaker to prevent any risk of electrical shock, which could occur if water makes contact with the electrical components of the heater.
Locate the gas valve on the heater, which is usually near the bottom of the unit. Turn this valve to the “pilot” position. This will stop the main burner from operating but keep the pilot light on.
You want to avoid having an active burner when dealing with water leaks, as it may create a hazardous situation.
Step 2: Shut Off the Water Supply
Once you’ve ensured the power is off, the next step is to stop the water flow into the heater. To do this, you need to locate the cold water shut-off valve, which is usually found on the pipe leading to the top of the water heater.
Turn the valve clockwise until it’s fully closed. Once you shut off the water supply, you’ve managed to prevent more water from entering the tank and increasing the leak.
Step 3: Drain the Water Heater
Draining the water heater is an important step to relieve pressure in the tank and reduce the volume of water that could leak out.
- Find the drain valve at the bottom of the water heater. Attach a standard garden hose to this valve, and make sure it’s securely connected.
- Position the other end of the hose to a safe drainage location, such as a floor drain, a large bucket, or even outside. Be mindful that the water will be hot, so take precautions to avoid burns.
- Open the valve to begin draining the tank. You might also need to open a hot water tap in your home to allow air to enter the system, which will help the water drain more smoothly.
Step 4: Identify the Source of the Leak
Not all leaks are the same, so it’s important to figure out where the water is coming from. The pressure relief valve, located on the side of the water heater near the top, is designed to release water if the tank’s pressure gets too high.
If this valve is leaking, it could be due to excessive pressure in the tank or a malfunctioning valve that needs to be replaced.
Sometimes, the issue might be as simple as a loose pipe fitting or connection. Check all the pipes connected to the water heater and tighten any that appear to be leaking.
If water is leaking directly from the tank itself, especially from the bottom, the tank is likely corroded.
Unfortunately, this type of leak usually indicates that the water heater has reached the end of its life and will need to be replaced. A temporary fix may help in the short term, but the tank will continue to deteriorate.
Step 5: Apply a Temporary Patch
For small leaks in the pipes or tank, you can use a temporary patch to stem the flow of water. Here are some materials you can use:
- Plumber’s Tape: Wrap waterproof plumber’s tape around the leaking area to create a seal. You can use this for leaks in pipe joints.
- Epoxy Putty: This putty can be molded and applied directly to the leaking area. It hardens quickly and provides a strong seal that can last for a short period.
- Pipe Repair Clamp: A pipe repair clamp is a specialized tool designed to cover and seal leaks. Place the clamp over the leak and tighten it according to the instructions. This can be particularly effective for leaks in the pipes leading to and from the water heater.
Step 6: Monitor the Leak
Once you’ve applied a temporary fix, you’ll need to carefully monitor the situation. You need to slowly turn the water supply back on by opening the cold water shut-off valve slightly. Check to see if your temporary fix is holding and whether the leak has stopped or slowed significantly.
If the leak seems to be under control, you can turn the power back on (either at the circuit breaker for an electric heater or by turning the gas valve to the “on” position for a gas heater).
However, you must use hot water sparingly, as the repair is only temporary and might not hold under heavy use. Meanwhile, a temporary fix is just that—temporary.
It’s important to contact a plumber as soon as possible to evaluate the situation and provide a permanent solution.
In the case of a tank leak, the water heater will likely need to be replaced. Even if the issue seems minor, you’ll need a professional inspection to prevent future problems and ensure your water heater is operating safely and efficiently.
Conclusion
Having your water heater leaking is not a very nice thing. It’s equally something you should never ignore. So, follow the procedures explained in this article to fix it temporarily so you can continue using it before you make a permanent fix.
