If the upper heating element of your Rheem Performance Plus is leaking water, it may indicate a faulty gasket or a corroded tank that needs immediate attention.
If your Rheem Performance Plus water heater is leaking from the upper heating element, you need to act fast. Water leaking through the element indicates a serious issue that could lead to tank failure or electrical hazards. This guide explains why it happens and how to fix it.
Why Is Water Leaking from the Upper Heating Element?
Water should never leak through a heating element. When this happens, it means one of three things:
- The element gasket has failed
- The element itself is corroded
- The tank has internal damage
The upper element is particularly vulnerable because it sits in the hottest part of the tank where mineral buildup occurs fastest. Rheem Performance models use brass drain valves for durability, but elements still wear out over time.
Signs You Need Immediate Repair
- Visible water dripping from upper element area
- Rust-colored water stains below the element
- Reduced hot water supply
- Tripping circuit breakers
How to Fix a Leaking Upper Heating Element
Step 1: Turn Off Power and Water
Safety first. Shut off power at the breaker and turn off the cold water supply. For 240V systems like the Rheem Performance Plus, use a multimeter to confirm power is off before working.
Step 2: Drain the Tank Partially
Connect a hose to the brass drain valve and open it slightly. You only need to lower the water level below the upper element, not drain completely.
Step 3: Remove and Inspect the Element
Use an element wrench to remove the upper heating element. Check both the element and tank threads for damage. Look for:
- Cracks in the element metal
- Worn or flattened gasket
- Pitting in the tank threads
Step 4: Replace or Repair
If the element is bad, replace it with an identical 4500W unit. For gasket issues, install a new high-temperature gasket. Apply pipe dope to threads before reinstalling.
For tank thread damage, use a torch kit to carefully clean threads or install a thread repair insert.
When to Call a Professional
Some situations require expert help:
- Visible cracks in the tank
- Severe corrosion around element port
- If you’re uncomfortable working with 240V systems
Rheem’s 6-year warranty may cover some repairs if your unit is relatively new.
Preventing Future Leaks
Extend your water heater’s life with these tips:
- Flush the tank annually to remove sediment
- Check anode rod every 2-3 years
- Install a whole-house water filter if you have hard water
- Consider a leak detector for early warnings
Understanding Rheem Performance Plus Heating Elements
The Rheem Performance Plus uses two 4500W elements that alternate heating. The upper element heats first, then transfers to the lower element. This design means:
- Upper elements work harder and fail more often
- Problems with the upper element can prevent the lower one from activating
- Both elements should be tested if one fails
According to water heater experts, elements typically last 5-10 years depending on water quality.
Cost to Repair vs Replace
| Repair | Cost |
|---|---|
| Replace upper element | $20-$50 (DIY) |
| Professional element replacement | $150-$300 |
| New Rheem Performance Plus 50gal | $600-$800 |
If your water heater is over 8 years old and leaking, replacement may be more cost-effective than repeated repairs.
Final Thoughts
A leaking upper heating element in your Rheem Performance Plus demands immediate attention. While some repairs are DIY-friendly, don’t hesitate to call a professional if you’re unsure. Regular maintenance can prevent many common water heater issues and extend your unit’s lifespan significantly.
