DIY Fixes for a Hot Water Tank Leaking from the Bottom

If you notice a leak coming from the bottom of your hot water tank, addressing the issue promptly is essential to prevent further damage. Here are some do-it-yourself (DIY) fixes you can try before calling a professional:

Turn Off the Power and Water Supply

Before attempting any repairs, it is crucial to turn off the power and water supply to your hot water tank. This ensures your safety and prevents any additional water damage. Locate the circuit breaker that controls the power to the tank and switch it off. Then, shut off the cold water supply valve connected to the tank.

The temperature and pressure relief valve (TPR valve) is a safety feature that helps regulate pressure inside the tank. A malfunctioning TPR valve can cause leaks. Start by placing a bucket under the discharge pipe connected to the TPR valve. Carefully lift the valve’s lever to allow hot water to flow into the bucket. If the water stops flowing once the lever is released or if water continues to leak, it may be necessary to replace the TPR valve. For more information on this issue, refer to our article on hot water tank pressure relief valve leaking.

Inspect the Drain Valve

The drain valve is located near the bottom of the tank and is used to flush out sediment or perform maintenance. Inspect the drain valve for any signs of leakage. If it is loose or damaged, it may need to be tightened or replaced. For detailed steps on how to address a drain valve leak, refer to our article on hot water tank drain valve leaking.

Examine the Tank for Corrosion or Cracks

Inspect the hot water tank itself for any signs of corrosion or cracks. Corrosion can weaken the tank, leading to leaks. If you notice any corrosion or cracks, it is best to contact a professional for further evaluation and repair.

Addressing Sediment Buildup

Sediment buildup at the bottom of the tank can cause leaks and other issues. To address this, you can flush the tank to remove the sediment. Begin by turning off the power and water supply to the tank. Connect a garden hose to the drain valve and place the other end in a suitable drainage area. Open the drain valve to allow the water to flow out, flushing out the sediment in the process. Once the water runs clear, close the drain valve and refill the tank.
