When your hot water heater, a device that heats and stores water for household use. Also known as a water tank, it's one of the most taken-for-granted appliances in your home—until it stops working. There’s no warning. One day you have hot showers, the next you’re standing under icy water wondering what went wrong. Most people assume their heater just wore out, but the truth is, hot water heater failure rarely happens by accident. It’s usually the result of slow, avoidable problems that build up over time.
One of the biggest killers of water heaters is sediment buildup, mineral deposits that sink to the bottom of the tank and trap heat. Over time, this layer acts like insulation, forcing the heater to work harder, burn out the heating element faster, and eventually crack the tank. In hard water areas, this can happen in as little as five years. Then there’s the anode rod, a sacrificial metal rod that attracts corrosive elements away from the tank. Most homeowners never check it. When it’s gone, the tank starts rusting from the inside out. A simple $50 part can extend your heater’s life by a decade—if you replace it on time.
High water pressure is another silent killer. If your home’s pressure exceeds 80 psi, it stresses the tank seams and valves. You won’t notice it until water starts pooling under the unit. And let’s not forget the thermostat. If it sticks, your water can boil inside the tank, creating steam pressure that leads to leaks or even explosions in extreme cases. These aren’t rare issues—they’re routine, and they show up in nearly every repair call we get in Warwick.
What you’ll find below are real fixes from real repair jobs. No theory. No fluff. Just what actually goes wrong with water heaters, how to spot the early signs before you’re left without hot water, and what steps you can take yourself before calling a pro.

Watch for signs like no hot water, strange noises, leaks, rust, or high bills-these mean your water heater is failing. Don’t wait for a burst. Replace it before it floods your home.
