Your grass looks like it is being watered too frequently.

The tried and true advice would be to water new sod 3x per day (breakfast, lunch, and dinner) lightly for 15 minutes just enough to keep it moist and not soggy. After 2 weeks, try pulling up the grass to ensure it is knit to the underlying soil. Assuming it is, then start to back off on the frequency and go up on the time. So change to once a day but water for 30 minutes. The ultimate idea is to water deeply but infrequently.

Bermuda is incredibly resilient. I'm going to suggest a very specific schedule. Frankly I didn't understand what you were saying in your description. Anyway, start by placing some cat food or tuna cans in the yard. Turn on the sprinklers and time how long it takes to fill all the cans. If a few cans fill faster or slower than the rest, then you'll need to adjust the sprinklers. I have oscillating sprinklers on a hose, and it takes a full 8 hours to fill the tuna cans for my water pressure. Every system is different, so you'll have to time your own. Once you have that time, that will be your watering time from now on. Every time you water you will water deeply all at one time. With some grasses you have to wean your way into this type of watering, but with bermuda, you can go cold turkey. Then as to frequency, usually in the hottest heat of summer (90s) you would water deeply once per week. If you have heat in the low 100s, then water once every 5 days. When the temp is in the 80s, you should be able to water once every 2 weeks. With temps in the 70s you can water once every 3 weeks. Use these as guidelines, but in no case should you ever water mature turf every day or two.
