What To Do When Your Hot Water Tank is Leaking

Hot water tanks are a crucial part of your home’s daily functioning, supplying hot water for everything from showers to dishwashing. However, like any appliance, they don’t last forever. With a typical lifespan of around 9 to 13 years, even well-maintained hot water tanks can start to leak over time.

A leaking hot water tank might seem minor initially, but if left unattended, it can lead to costly water damage in your home. Knowing how to respond quickly when your hot water tank starts leaking can make all the difference.

Here’s a step-by-step guide on what to do if you notice your hot water tank leaking.

1. Identify the Source of the Leak

Before taking any further action, determine where the leak is coming from. Sometimes, water pooling around the tank may be due to condensation or leaks from nearby pipes, not the tank itself.

To check:

  • Wipe up any standing water and place paper towels around the tank to help identify the source.
  • Watch to see if new water appears and if it’s coming directly from the tank.

If the leak is from the base, it often indicates a more serious issue like internal corrosion. Leaks from the top or sides might be due to loose fittings or faulty valves.

2. Turn Off the Power

Safety is crucial. Shut off the power supply to your hot water tank to reduce the risk of accidents.

For electric water heaters, turn off the breaker for your water heater in the home’s electrical panel. Working with electricity near water can be dangerous, so this step is essential.

For gas water heaters, locate the dial or switch on top of the tank and turn it to the “off” position. Avoid shutting off the main gas valve if possible, as these can be tricky to handle and could lead to further issues if not handled properly.

3. Shut Off the Water Supply

Next, stop the water from entering the tank. Most hot water tanks have a cold water shut-off valve located above the tank. Turn this valve clockwise or pull down the handle to prevent further water from entering the tank.

If you can’t reach the valve or the area is too hot, shut off your home’s main water supply as a backup. Knowing where your main shut-off valve is located is helpful in any plumbing emergency!

4. Drain the Tank (If Safe)

If it’s safe to do so, you may want to drain the hot water tank to minimize water damage. Attach a hose to the drain valve near the bottom of the tank and lead it to a safe drainage area. Remember, the water may still be extremely hot, so exercise caution.

5. Call a Professional Plumber

After taking these steps, it’s time to call in a professional. A plumber can inspect the leak and determine whether the tank needs repair or replacement. If the leak is coming from the base, it often points to internal failure, which usually requires a new tank.

Attempting to repair the tank yourself can lead to further complications, as hot water tanks are complex systems that require precise handling. A qualified plumber can quickly assess the situation and provide the best course of action.
