Maintenance Tips for Rheem Water Heaters
Maintaining your Rheem water heater ensures efficient performance and extends its lifespan. Implement these practical tips to keep your unit in top shape:
Regular Inspections
- Check the Anode Rod: Inspect this component every 1-2 years. Its purpose is to prevent tank corrosion. Replace it if significantly corroded.
