Draining a drain pipe involves a few key steps to prevent leaks and ensure proper drainage. This response assumes you're asking about draining a water heater drain pipe, as that's the scenario described in the reference.
Here's how to do it:
-
Turn off the cold water inlet valve: This stops more water from entering the tank. This is according to the reference.
-
Connect a garden hose: Attach a garden hose to the drain valve on the water heater. The hose should be long enough to reach outside or to a suitable drain location.
-
Open the drain valve: Slowly open the drain valve to allow the water to flow out through the hose.
-
Assist the draining process: To speed up the drainage, you can do one (or both) of the following, according to the reference:

- Open the pressure relief valve on the water heater. Be careful as hot water or steam may escape.
By following these steps, you can effectively drain a water heater's drain pipe.
