Newly laid sod needs frequent watering, but you don't want to create a
swimming pool. Perhaps 10 minutes every day for the first week or two, if
you live in a dry hot climate, maybe 10 minutes in the morning, and 10
minutes in the afternoon, or early evening.
The roots are shallow, so you want to make sure the top quarter inch of soil
is moist, like a squeezed sponge. Not watering after the first 2 hours
probably didn't harm anything, sod on pallets for hours in the nursery, and
does just fine. Ease back on the watering would be my first suggestion, give
it a week or two, of just light but frequent watering.
Also in the future, consider breaking your posts up into paragraphs, it
makes it much easier to read. People tend to skip over posts that are over 1
screen in length.
