What is the most important safety device for all water heaters?

What It Does

This valve is designed to automatically release hot water or steam if the temperature or pressure inside your tank climbs too high. By venting excess pressure, it prevents tank ruptures, leaks, or even dangerous explosions.

Why It Matters

• Safety First: The T&P valve is the last line of defense if other controls fail.

• Code-Compliant: Building codes require this valve for all water heaters.

• Peace of Mind: Knowing it’s working properly means your family is safe.

How to Keep It Working

• Test it once a year. Lift the small lever to ensure water flows out, then snaps shut.

• Never block or cap the discharge pipe. It must stay open and unobstructed.

• Replace at the first sign of trouble. Dripping, corrosion, or a stuck lever means it’s time for a new one.

Bottom Line

A properly functioning T&P valve is the single most important safety device on your water heater. Without it, pressure and temperature can build to dangerous levels.

If you’re unsure whether your valve is working correctly, Water Heaters Garland can inspect and replace it quickly.
