    Our water heater works for a few hours then goes out. I restart the pilot light, it works for a while, then goes out. Any thoughts?

    How old is the water heater? Is it a newer sealed burner design?

    The water heater is about 5 years and yes it is a sealed burner. It seems that I light it, it heats up the tank, then the pilot light goes completely out.

    There is a screen on the bottom of the tank that is plugged with lint and dust.
