SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

I am installing a new sprinkler system as a DIY. I've been reading about (as well as studying and asking questions) for months now so I'm going to give it a try. I live in the Maryland area and the gist of what I hear is:

1. Use Poly piping vs. PVC because of the cold weather
2. Use 1'' vs. 3/4'' with 48psi at 8gpm since I have to 300ft runs and want want to add additional friction
3. Use funny pipe & barb connections to hook up heads (Rainbird 5004)

So here are my remaining questions

1. What is the best way to hook up poly ends to my valves? I am thinking threaded poly ends to a female thread valve. Correct?
2. What is the MAX length I should have for a funny pipe hookup to a head? Most will be 1ft or so but I have some I could really use 5-7 ft for flexiblity
3. Can I take a lateral line running a zone and split it up? i.e. 5ft, T it with 2 heads (4 heads total) to each T run or should I keep it all a single line?

Thanks!
