I ended up buying Rainbird funny pipe (3/8") and the RB fittings...They work awesome. My longest run is about 4 1/2 feet from the riser, Thanks to all who responded.

Different plastic material in the name brands. Tighten a no-name into a threaded insert fitting, and it can bind. Then the barbed end you're pushing against can break right off. No fun at all.

By the way, stick with the 'name brand' funny pipe fittings, either Toro or Rainbird.

Funny pipe will be easy and work fine. Go with real funny pipe. It is self sealing so you dont need any pipe clams either. Get fpt funnypipe fitting and screw that on to the riser after taking off the rotor. Run your funny pipe the distance you need then a 3/4 mpt funny pipe fitting screw the rotor onto that and put it in the ground.

WOW...genuine funny pipe is only 3/8 of an inch...? I thought it was at least 1/2 inch and here i was concerned with 3/4" being too small. Does this funny pipe and fitting cause much problems...? Clogging, kinks, others i don't know about? Does anybody else have more input to this matter, So far, Thanks for the replies.

<b>No poly pipe needed</b> - if all you are doing is locating individual sprinkler heads within the aforementioned ten feet from the PVC pipe. You would use the genuine 3/8" funny pipe, and the special fittings that go with them.

Funny pipe is more like 3/8 inch. And 3/4 poly is fine for laterals but if the rest of the system is 1 in then just use 1in poly for the laterals.

That shows my knowledge in regards to funny pipe...i thought funny pipe was actually poly made material and came in many diameters. Can i use poly pipe to act as funny pipe..???

It was a roll of 100' (3/4") at home depot, i guesss thats what it was, poly pipe. Im not sure if i explained myself correct....i call the pipe after the inline valve (Laterals) am i right?

Yes...this is 1" pvc pipe with risers and elbows reduced to accept 3/4" Riser that currently connect my Rainbird 5000 plus rotors to the pvc line, via 5" sch 80 risers.

You said " use 1" poly"....so what do i do, 1" barbed elbow that reduces to 3/4" male thread? Then from there i use the 1" poly pipe to another 1" barbed elbow that reducees to 3/4" to the rotor itself..? Can i use any length 1" poly pipe under 10' with this method..? I hope im explaing this correctly, or better yet, please advise on a method without having to cut the pvc pipe.

Just going on gut feeling (based on what I've learned at places like www.irrigationtutorials.com and my engineering background) but I would say that (as far as flow and pressures are concerned) 3/4" funny pipe going to a single rotor would be just fine for any length less than 10 feet. What I'm not sure about is how well long lengths of funny pipe will withstand surface traffic over time.
