What Causes a Hot Water Heater to Leak, and How to Prevent It

A leaking hot water heater is more than just an inconvenience; it can lead to water damage, higher utility bills, and even system failure. So in this blog, the experts at Billy the Sunshine Plumber in Tampa Bay take a look at the common reasons why water heaters leak, what you can do to prevent it, and what to do if you notice a leak.

Common Causes of Water Heater Leaks

1. Corroded Tank: Over time, the metal tank in your water heater can corrode. And this is especially pervasive if the anode rod, which prevents rust, wears out. So, if this happens your water heater is susceptible to corrosion that causes small holes that allow water to seep out.
2. Loose Connections: Water heaters have inlet and outlet pipes to deliver and remove hot water. And if these fittings or connections are loose or damaged, they can cause leaks.
3. Temperature and Pressure (T&P) Relief Valve Issues: This valve releases controls pressure to prevent your tank from bursting. So, if it malfunctions or has too much pressure, it might leak to release pressure.
4. Drain Valve Leaks: The drain valve at the base of the tank can become loose or fail, causing water to leak.
5. Sediment Build-Up: Over time, minerals in the water can settle at the bottom of the tank. And this can causes it to overheat and weaken, potentially leading to leaks.

Steps to Prevent Water Heater Leaks

1. Regular Maintenance: Flushing the tank once or twice a year removes sediment build-up, improving efficiency and extending the tank’s life.
2. Inspect and Replace the Anode Rod: Check the anode rod every 2-3 years and replace it when it becomes overly corroded. Because a fresh rod will protect the tank from rust.
3. Check Connections and Fittings: Inspect the pipes and fittings around the tank occasionally to ensure they’re secure and not showing signs of wear.
4. Test the T&P Valve: Lift the T&P valve’s lever slightly and allow it to snap back into place to test. And if it doesn’t release water, replace it to prevent excess pressure from damaging the tank.
5. Install a Water Softener: A water softener or a filtration system can reduce mineral build-up in the tank if you have hard water. And this will help to prevent overheating and sediment accumulation.

What to Do If You Notice a Leak

If you spot a leak, turn off the power to the water heater (electric or gas) and shut off the water supply to prevent further damage. And then call Billy the Sunshine Plumber for a thorough inspection and repair. Because whether you’re in Pinellas, Pasco, Citrus or Hernando County, Billy’s is available to help.
