Understanding a Common Plumbing Emergency
Discovering a hot water heater leaking from the bottom can be stressful—and it’s not something to ignore. This type of leak may signal anything from a minor valve issue to full tank failure. Left unchecked, it can cause significant water damage, mold growth, or even a complete lack of hot water in your home.
If you’ve noticed water pooling around your water heater, here’s what you need to know—and how our experts at Glanz Buffat can help homeowners across Louisville, Shepherdsville, Jeffersontown, La Grange, St. Matthews, and Middletown get back to hot showers and peace of mind fast.
Common Reasons Your Water Heater Is Leaking from the Bottom
1. Faulty Drain Valve
Your water heater has a drain valve at the bottom of the tank that can become loose or fail over time. A faulty or improperly closed valve can leak slowly, causing a puddle that might appear to be from the tank itself.
2. Sediment Buildup
Over time, sediment collects in the bottom of the tank. When not flushed regularly, that buildup can lead to overheating, corrosion, and tank failure—one of the most common causes of a leak from the base of your unit.
3. Cracked Internal Tank
Most traditional hot water heaters consist of a steel outer shell and a glass-lined interior tank. Cracks in the internal tank, often caused by age or corrosion, can result in consistent leaking from the bottom of the unit.
4. Malfunctioning Temperature & Pressure Relief Valve
When this safety valve fails or becomes blocked, excess pressure may build up inside the tank, causing leaks from the bottom or other weak points.
If you’re not sure where the leak is coming from, our licensed plumbers can perform a full plumbing inspection and water heater diagnosis to quickly pinpoint the issue.
What Should You Do If Your Water Heater is Leaking?
If your hot water heater is leaking from the bottom, start by turning off the power supply—either the breaker (for electric units) or gas valve. Then shut off the water supply to prevent further flooding. Do not attempt to open or disassemble any parts if you’re unsure what’s causing the leak. Water and electricity can be a dangerous combination.
Instead, reach out to a professional like Glanz Buffat for reliable water heater repair or replacement services. Our team is available to help you decide whether the issue is repairable or if you’re better off installing a new, energy-efficient water heater.

When It’s Time to Replace Instead of Repair
