Step 8 · Test the New Valve
The final step is to verify the mechanical operation of the new valve. Allow the water heater some time to heat the water. Place a bucket under the end of the discharge pipe. Wearing gloves to protect from hot water, carefully lift the manual release lever on the top of the new T&P valve. A gush of hot water should exit the pipe. Let it run for 2-3 seconds, then release the lever. It should snap back into its original position, and the water flow must stop completely. If the valve continues to drip, lift the lever again briefly to flush any potential debris from the seal. If it still leaks, the new valve may be defective and should be replaced.
