The plastic dip tube in my heater was made with a 1/8" hole a few
inches from the top. What's the purpose of this hole, and what
direction should it face?

It is to prevent siphoning the water back out of the heater if the water
pressure is lost. It makes no difference which way it is turned.

Thanks, Don. Now I don't have to worry if I installed the tube wrong
or not. :) I originally thought the hole was for stirring up the
water around the thermostat to prevent a hot spot next to it that would
turn it off at too low a temperature.

I seem to remember something about that. As I recall it makes no
difference where it points.

This is Turtle.

You got me confussed here. I just can't picture a Dip Tube 1/8" Plastic ,
mounted on the side, and pointed in any direction. Can you explain to me what it
being talked about ?
