The Importance of a Working Pressure Relief Valve
Your water heater might not be flashy, but it’s essential. That small, humble part—the pressure relief valve—plays a big role in keeping your home safe.
Why the Pressure Relief Valve Matters
This little valve is your water heater’s built-in safety net. As water heats and pressure builds, the valve releases excess pressure. Without it, pressure can rise to dangerous levels—causing leaks, cracks, or even a tank explosion.
Signs a Valve Is Failing
- Dripping or leaking: Constant drips may signal wear or sticking.
- No response when tested: If the handle lifts but nothing happens, it might be clogged or broken.
- Rust or corrosion: Visible wear means replacement is due.
- Weird noises or overheating: Could be pressure issues inside the tank.
Don’t ignore these signs—small problems can lead to major repairs.
How to Maintain Your Valve
1. Test It Every Year
Lift the handle slightly—water should release and stop. If not, call your plumber.
2. Address Leaks Immediately
Leaks usually mean high pressure or a bad valve—don’t wait to get it checked.
3. Schedule Routine Maintenance
A quick inspection can catch minor issues before they become costly disasters.
4. Know When to Replace
Water heaters over 8–12 years old put stress on valves. Consider a full replacement if your unit’s aging.
