What to Do When Your Water Heater Pressure Release Valve Is Leaking

A leaking water heater pressure release valve (also called the temperature and pressure relief (T&P) valve) can be a sign of a serious issue. This small but essential safety device is designed to release excess pressure from your water heater, preventing dangerous explosions. If you notice water leaking from this valve, don’t ignore it—take action immediately!

Why Is My Water Heater’s T&P Valve Leaking?

There are a few common reasons why your pressure release valve may be leaking:

✅ Excessive Pressure – If your water heater builds up too much pressure, the valve will open to release some water and prevent a dangerous situation.

✅ Overheating – When the water temperature gets too high, the valve may leak to relieve the excess heat and pressure.

✅ Faulty or Worn-Out Valve – Like any plumbing component, the T&P valve can wear out over time and may need to be replaced.

✅ Sediment Buildup – Hard water and mineral deposits can cause the valve to malfunction, leading to leaks.

Steps to Take When You Notice a Leak

If you see water dripping or pooling around your water heater, follow these steps:

🔹 Step 1: Turn Off the Power

• For gas water heaters: Turn the thermostat to the "pilot" setting.

• For electric water heaters: Switch off the breaker connected to the water heater.

🔹 Step 2: Check the Temperature SettingEnsure your water heater’s temperature is set between 120-140°F. If it’s set too high, it can cause overheating and excessive pressure buildup.

🔹 Step 3: Test the T&P ValvePlace a bucket under the discharge pipe and lift the valve’s lever for a few seconds. If water flows out and stops once you release the lever, the valve may be functioning correctly. If it continues to leak, it may be faulty.

🔹 Step 4: Look for Signs of High PressureIf your home has high water pressure (above 80 psi), it can cause stress on your water heater and plumbing. Installing a pressure-reducing valve (PRV) can help regulate this.

🔹 Step 5: Call a Professional PlumberIf the leak continues after testing the valve, it’s time to call a licensed plumber. The issue could be a failing valve, an overheated system, or excessive pressure—all of which require professional attention.
