When the sod was newly installed we watered the lawn about every two
days . Then after it was more established we did twice a week for 20
minutes. Now we are at 30 minutes, twice a week.

30 minutes watering won't do anything for your lawn. That won't even give a
measurable amount. Put out some containers and water until you have 1/2", and
water at least 2 times a week until the grass is well established, then you
can cut back to once a week. You'll still need to water long enough to get at
least that 1/2" of water down.
