Water Heater drain line?
Posted by Kevin Shertz on November 23, 1999 at 16:02:28:

I'm about to have an old gas water heater replaced in my recently-purchased house, and the existing water heater has a drain line from the pressure relief valve to the outside of the house.

When the new one is installed, is this line really necessary? Seems to me that you'd want to have it drain to a point inside (having a drain pan underneath) so you can see a problem before it worsens.

Any thoughts?
