What Happens If Your Temperature Pressure Relief Valve Fails
2025-08-29
Your water heater’s temperature pressure relief (TPR) valve is its most critical safety component. But what happens when this vital part fails? The consequences can range from minor leaks to dangerous ruptures. Understanding these risks can help you take timely action and avoid costly—or even hazardous—situations.
A failed TPR valve cannot release excess pressure or temperature from the water heater tank. This may lead to excessive internal pressure, which can cause the tank to leak, rupture, or even explode in extreme cases. Additionally, malfunctioning valves may drip continuously or fail to open when needed, putting your household at risk.
That’s why installing a high-quality TPU Life-saving Valve is non-negotiable. At Zhenhua Electrical, we engineer our valves to the highest standards of reliability and safety.

TPU Life-saving Valve FAQ
What are the signs of a failing TPR valve?
Common signs include continuous dripping, no discharge during testing, visible corrosion, or failure to reseal after lifting the test lever.
Can I replace a TPR valve myself?
While technically possible, we recommend hiring a licensed professional to ensure proper installation and avoid safety risks. Always use certified products like the Zhenhua Electrical TPU Life-saving Valve.
How often should I test the valve?
Test every six months. Lift the lever gently until water flows, then release. If it doesn’t flow or doesn’t stop, replace it immediately.
Don't gamble with safety. A faulty valve isn’t just an inconvenience—it’s a risk to your home and family. Ensure your system is protected with a certified Zhenhua Electrical TPU Life-saving Valve.
