<br />As far as the original design it is difficult to picture so that makes it hard for me to comment. I really like blazing saddles for poly pipe and would use these any day over the slip type fittings. Also I cant comment ofn the febco pvb because i have never used it but I do know that febco is a reputable company and make quality products.

Do you at least recommend a PVB to be connected to my well then? Is this the normal practice or most only for city water installs? Thanks again. I'm planning on putting through my order today.

Go with the blazing saddles if your defintely not a contractor-
IF not your going to have to purchase a tool to crimp and a bag on crimps plus your slip adapters. The Blazings have it all!

<br />Cool. I have not used the 3500 rotors and am not familiar with the features. I like the features of the rainbird 5000+ and the hunter pgp is the 1 rotor in the country.

So should I go with my orginal design found here - http://www.sprinklertalk.com/forum/topic.asp?TOPIC_ID=554 but instead use rotors then? If so, I'll go ahead and put my order in. Also, what about the Febco PVB and Blazing saddles taps mentioned earlier? Would you recommend these products? Thanks

<br />I am not clear on why you only want a 15 ft throw. If you use rotors you shold be able to go down each edge of the 56 bx 36 and get 36 ft distance out of the rotor and get head to head coverage. Are you following me or am I confused about your design? For rotors either the rainbird 5000+ or hunter pgp and you should be able to get 30-35ft dist with these. Check the specs at sprinkler warehouse.

The reason that I quoted 15' of throw for the rotors was based on my old design for the sprayers ( would be for 4 rotors on each side - with half pattern). What you're saying makes pretty good sense though - you are saying use 4 rotors total with 36' of throw, correct? The reason why I designed it this way was because I didn't want too much overspray on my rock garden. See this post: http://www.sprinklertalk.com/forum/topic.asp?TOPIC_ID=554
I think the rainbird 3500 series rotors will still have descent gpm flow vs. my original plan of using sprayers

For 15' rotors. Go with the new HUNTER PGJ's. They are basically the PGP juniors made for smaller radisus where you would normally use a spray. Same contruction and performance as a PGP

<br />Based on your zone flow rates you have 15gpm not 22gpm. You may not need to split, provided your well and pump can deliver at least this amount. Remember that if you are running from a well through a pump w/out a pressure tank, whether you do 15gpm or 7.5gpm,all your zones will need to be approximately the same flow rate to keep your pump from cycling and wearing out. At 15ft. spacing you are borderline of spray heads versus rotors. You will definetly use sprays on the shrubs, I prefer Hunter Pro series with the 8" or 12" risers for shrubs. For the yard it is your call, sounds like you are going with rotors, you'll impress the neighbors more with rotors, but they cost more too. Rotors I use are Hunter PGP or I-20 if the terrain is not level. You can order through sprinkler warehouse.

Cost isn't too much of an issue right now due to me doing two zones for the time being. How did you arrive at 15 gpm for my flow requirements. Obviously, i must have miscalculated, can you inform me what I did wrong in my calculations?

A little off topic, I'm thinking of getting a Febco 1" PVB backflow device instead of this cheap plastic crap the lowes guy sold me (it will work, don't know how long though). Should I also go with those blazing saddles taps for the sprinkler connections (to tap sched. 40 PVC)? those look really nice.

One more thing guys, no one has recommended what type of rotors to go with for 15' spacing. I really like the new 3500 series rotors that rainbird put out. If advised to, I will go ahead and order these pronto along with the Febco PVB. Thanks again. I'm learning alot.
