How to Fix a Leaky Hot Water Tank

A hot water tank leaking is more than an inconvenience. It’s a sign of a potentially serious problem that requires immediate attention. While you may be tempted to handle it yourself, water heaters involve pressurized systems, electricity or gas, and safety mechanisms that pose real risks if handled incorrectly. At High Priority Plumbing, we understand how overwhelming plumbing issues can be, and we’re here to provide the professional expertise needed to resolve them quickly and safely.

Step 1: Ensure Your Safety

Before doing anything else, prioritize safety. For electric heaters, switch off the breaker in your electrical panel. If you have a gas water heater, turn the gas control valve to the “off” position. This step is critical, but it’s also where many homeowners stop and call in a professional. Handling a hot water tank leaking beyond this point can be risky without the right tools and training.

Step 2: Shut Off the Water Supply

Locate the cold water shut-off valve at the top of your heater and turn it clockwise. This will prevent additional water from entering the tank, reducing the risk of flooding. But remember: stopping the leak doesn’t solve the problem. A professional plumber will need to inspect the system to fix leaking water heater issues and prevent further damage properly.

Step 3: Identify (Don’t Attempt to Fix) the Source of the Leak

Common causes of leaks include:

  • Loose fittings or connections that require proper sealing
  • Faulty pressure relief valves caused by high temperature or pressure
  • Corroded tank walls, which typically mean the water heater needs replacement

It may seem easy to tighten a fitting or replace a valve yourself, but these fixes can fail without proper diagnosis. What appears minor often signals a deeper issue, which is why water heater leak repair is best left to licensed professionals.

Step 4: Leave the Repairs to the Experts

Attempting to fix leaking water heater problems alone can create more serious issues, including flooding or gas leaks. At High Priority Plumbing, our experienced team specializes in water heater leak repair for residential and commercial systems. We don’t just patch the problem. We address the root cause to ensure lasting results.
