Maintenance Tips for Rheem Water Heaters
Regular maintenance keeps your Rheem water heater running efficiently and prolongs its lifespan. Follow these essential tips to ensure your unit remains in top shape.
Regular Inspection and Cleaning
Inspect your water heater every six months for signs of wear or damage. Look for corrosion, leaks, or rust on the tank and pipes. Clean the tank’s exterior and surrounding area to prevent dust buildup, which can cause overheating.
