Abstract
Abstract This invention relates to a floor drain and methods for its installation, more specifically to a floor or shower drain having two sets of weep holes and to a method for its installation. Conventional drains generally in use today have only one set of weep holes to drain water which may seep down to a water impervious pan. As a result, if the shower stall is installed improperly, water may seep out and cause extensive water damage. The invention relates to a shower drain installation which will be effective in preventing water damage even if the subfloor is not ideally suited for promoting drainage in a shower.
