I backflow is alot, shutoffs are small but add up, linear feet add up. I think you need to read up on this. Not to hard at all but you need to know WHAT to use as a process. Been there done that.

I don't think you are understanding what some here have said. There is more to it than just pressure.

I mean a spray head only spraying at 180 degrees with a short radius (About 4 feet)

How do you suggest that I should check to see if there is enough "service" through the line to power the additional heads?

Without a flow meter? Determine your maximum supply flow at the minimum required dynamic pressure. Then measure your nozzle pressures and use the charts to determine a rough current zone flow rate. Then use more charts with a known pipe size and the above data to determine what you can do or not do.

Swap out the original nozzles with precision side strips and put them in the new heads. This would be your best bet.

Post this info:

Water meter size, mainline size, supply line size, length of mainline to proposed extension, static pressure, Backflow type and size.

I don't like add-a-zone, but in this case you might think about it.

all are easy. I had to run under my 16ft concrete driveway. Again water is your friend! Just go slow.

I like pulling the 1" or 1.250" poly pipe, as long as one guy is holding the role, 8 mph! I did my yard with over 2,000 feet of pipe in 2 hours.
