Where to put weeping tile / perimeter drain?

jchwang | Posted in Green Building Techniques on

I have heard of a suggestion to locate drain below and farther away from footing to minimize heat transfer through footing to water rushing through the drain pipe.

Also, if my footing is well above the water table, should I orient the holes up (for rainwater), down (rising water) or toward the footing (keep water away from footing)?

    Unless your site is extraordinarily wet, you shouldn't have "water rushing through the drain pipe." The usual location for the pipe is adjacent to the footing.

    The holes should be oriented at 4:00 o'clock and 8:00 o'clock.
