I'm a little concerned about your regulator. It should have been a 10psi with kit "A" or a 15 psi with kit "B". In either case the output variance would be minimal. Perhaps about .25gpm.

As far as how long to water... I suggest you dig down with a spade and see how it is doing. Different soil types will show different results. After the first 2 or 3 cycles you should have a good feel for it.

I hope this helps!
