Your water heater is one of the hardest-working appliances in your home. It provides the comfort of hot showers, clean dishes, and sanitized laundry — yet it’s often forgotten until something goes wrong. Like any major appliance, a water heater needs regular maintenance to keep it running efficiently and to extend its lifespan. The good news is that a few simple steps can help you avoid costly repairs or early replacement.
Here’s how to get the most out of your water heater and keep it in peak condition for years to come.
1. Flush the Tank Regularly
Over time, sediment from minerals in your water supply builds up at the bottom of your tank. This layer of sediment acts as insulation between the water and the heating element, making the heater work harder to reach the desired temperature. The result? Higher energy bills and reduced efficiency. Flushing your tank once or twice a year helps remove sediment, improve performance, and prevent corrosion. If you’re not comfortable doing this yourself, a professional plumber can handle the process safely and correctly.
2. Check the Temperature Setting
Most homeowners never think to adjust their water heater’s temperature, but setting it too high can waste energy and strain the unit. The ideal temperature for most systems is around 120°F. This setting provides hot water that’s comfortable and safe while also preventing scalding and lowering energy costs. It also reduces stress on internal components, helping the heater last longer.
3. Inspect and Replace the Anode Rod
The anode rod is a small but critical component that helps prevent your water heater from rusting. It attracts corrosive minerals and protects the tank’s steel lining. Over time, this rod wears out and needs replacement — usually every three to five years. Ignoring it can lead to tank corrosion and leaks. Having a plumber inspect the anode rod during your maintenance visit ensures your tank stays protected and extends its life significantly.
4. Test the Pressure Relief Valve
Every water heater has a pressure relief valve, which prevents the tank from over-pressurizing — an important safety feature. To test it, place a bucket under the discharge pipe and lift the valve’s lever slightly. If water flows out, it’s working properly. If not, or if the valve leaks afterward, it’s time to replace it. This simple check prevents dangerous pressure buildup and costly damage.
5. Insulate the Tank and Pipes
Insulating your water heater and the first few feet of nearby hot water pipes can significantly reduce heat loss. This means your water heater won’t have to work as hard to maintain hot water, lowering energy usage and extending its lifespan. Insulation kits are inexpensive and easy to install, and professional plumbers can provide high-quality insulation that’s both safe and effective.
6. Schedule Annual Professional Maintenance
Even if you perform basic upkeep, having a licensed plumber inspect your water heater once a year is a smart investment. A professional will check for leaks, corrosion, worn parts, and any signs of inefficiency. They can also perform tune-ups that improve performance, reduce energy waste, and help you avoid unexpected breakdowns.
When It’s Time for Replacement
No water heater lasts forever. Most units have a lifespan of about 8–12 years, depending on maintenance and water quality. If you notice rusty water, strange noises, or inconsistent hot water, it might be time to consider a replacement. Newer models are more energy-efficient and provide consistent heating while saving on utility costs.
