Why Should You Drain Your Rheem Water Heater?
Over time, sediment and mineral deposits build up inside your Rheem water heater, reducing efficiency and possibly causing damage. Draining your water heater helps:
- Improve heating efficiency
- Extend the lifespan of your water heater
- Prevent clogging and noisy operation
- Ensure clean and safe water usage
Experts recommend draining your water heater every 6 to 12 months to maintain optimal performance.
Tools You’ll Need
Before you begin, gather these essential tools:
- Garden hose (long enough to reach a safe drainage area)
- Bucket or towel (to catch any spills)
- Adjustable wrench (if needed for the drain valve)
- Flathead screwdriver (for gas water heaters)
- Gloves (for safety)
Step-by-Step Guide on How to Drain a Rheem Water Heater
Step 1: Turn Off the Water Heater
For Electric Rheem Water Heaters:
- Switch off the power supply at the circuit breaker.
For Gas Rheem Water Heaters:
- Set the thermostat to “Pilot” mode.
- Turn off the gas supply valve for safety.
Step 2: Turn Off the Cold Water Supply
- Locate the cold water inlet valve at the top of the water heater.
- Turn it clockwise to stop water from entering the tank.
Step 3: Attach a Hose to the Drain Valve
- Connect a garden hose to the drain valve at the bottom of the water heater.
- Place the other end of the hose in a floor drain, outside, or a bucket.
Tip: Ensure the drainage area is safe and can handle hot water.
Step 4: Open a Hot Water Faucet
- Open a hot water tap in your home to allow air into the system.
- This will help the water flow out smoothly from the tank.
Step 5: Open the Drain Valve
- Turn the drain valve counterclockwise to release water.
- Let the water drain completely to flush out any sediment.
- If water drains slowly, open the pressure relief valve to improve flow.
Step 6: Flush Out Remaining Sediment
- Turn on the cold water supply for a few minutes while the drain valve is open.
- This will flush out any leftover sediment from the tank.
Step 7: Close the Drain Valve and Refill the Tank
- Once the water runs clear, close the drain valve tightly.
- Remove the garden hose.
- Turn on the cold water supply to refill the tank.
- Keep a hot water tap open to release trapped air.
Step 8: Turn the Water Heater Back On
For Electric Rheem Water Heaters:
- Turn the power back on at the circuit breaker.
For Gas Rheem Water Heaters:
- Turn the gas supply back on.
- Set the thermostat to your desired temperature.
How to Prevent Sediment Buildup in a Rheem Water Heater
- Drain and flush your water heater every 6-12 months.
- Install a water softener if you have hard water.
- Check the anode rod every few years and replace if necessary.
- Use a sediment filter to reduce mineral buildup.
When to Call a Professional
If you notice any of these issues, contact a licensed plumber:
- Leaking water heater even after closing the drain valve
- Noisy operation due to excessive sediment buildup
- Rusty or discolored water after draining
- Slow draining issues even with flushing
