then your answer is no you will not damage or under perform if you stay within the 10 peercent rule, meaning if the the static is 62psi than your zone should not exceed 12gpm. that mmeans you can get away with the most 4 pgp with a nozzels at 4#7 or going along the fence at 30ft spaces corner #7 and middle #9 and corner #7 and with the little bit of 1/2 will not hurt your system. I use 1/2 poly from the pvc to the heads with the right barb fittings, i make them myself, or you can buy them already made. just trying to help.

I looked up these parts and the barb on them accomodates 1/2" pipe not 3/4". So, the question is, will I damage or force the rotor to underperform by using &lt;= 2' of 1/2" funny pipe?

What does everyone use for their swing joints for these rotors? I thought based upon my reading that they were well regarded so I'm surprised that it isn't more apparent what the proper method is. I'm interested in everyone's thoughts. Thanks.

I am a homeowner in Tennessee. I think the link you provided is probably the right fitting, but I'm not 100% certain because it doesn't state the size of the barb, I'm assuming that because the threaded end is 3/4" that the barb would accomodate 3/4" pipe as well, but I'd like to know for sure. If the barb does accomodate 3/4", why doesn't sprinklerwarehouse sell 3/4" swing pipe? I just want to follow standard industry practice here, and it doesn't seem like using 3/4" funny pipe is it. But if not, what is? Should I just bite the bullet and buy some Hunter swing joints and be done with it? I'd love to hear everyone's thoughts, I can't be the only person using these rotors?!

I plan on putting the rotors within 1-2' of the laterals. I would love to use 3/4" funny pipe but am having trouble finding it. Am I missing it somewhere?

<br />need to know more information like, pressure and meter size and where the meter is located. more info the better.
<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">

The static pressure at the nearest hose bib was measured at 62 psi, the lateral runs will all be within 125' from the valves which will be about 50' from the meter. Was planning on using 1" PVC for the laterals. I couldn't find the meter size (by looking on the meter itself), but I believe the mainline (measured at the master control valve just a few feet away from the meter) is 1" PVC.

What do you think?
