Thanks for the advice.  The sod was laid on basically clay soil, We have been getting rain every couple days for the last 2 weeks.  The clay holds the moisture.  2 or 3 days after a inch rain the ground is still very soft, so soft its hard to push a mower on flat ground.  I did some landscaping and had to remove some sod, the sod roots are getting into the soil below.  I did apply some scotts turf builder this weekend.  I do not plan to water for a while,  I figure that should help the roots to get deeper to find the moisture.
