Are Nelson rotors any good?

    I was going through a customer's system last season and I was impressed with the Nelson's spray pattern. Can anyone tell me how they hold up.

    Not all that great. They don't compare to the PGP's they imitate.

    We used some Nelson 6000's for a while, years ago. At one time they weren't bad sprinklers, and our local supplier, then, pushed them and backed them up. I have no idea where they stand as far as quality these days, but I don't see many newer ones out there.

    Homeowners seemed to have a greater fondness for them than installers because of their perceived simple adjustment. At the same time, that simple adjustment mechanism did not allow for quite as precise settings, and it would take an installer longer to set a Nelson than most other brands. The caps were notorious for coming off if they were not secured with a screw, and the click-set mechanism in older ones often failed. Both were easily replaced , but a nuisanse. But I noticed more and more Nelsons having problems sticking up early on. At one time you'd run across a lawn full of 5 year-old Nelsons with one or two that would stick. Then it seemed to become three or four in a lawn of 2 year-old Nelsons. That is when I quit even carrying any in the truck for replacements.

    Bottom line, in 2007, I think there are much better choices. I will say this though. Their rotors may be the best thing they make :eek:

    Personally, I can't stand them, and I don't think too highly of any of the outfits who install them. Around here, you get them at the plumbing suppliers', not at the irrigation shops.

    We have one site that has some Nelson rotors and valves in its system and they're working fine. These are probably over 20 years old since this is at the district office complex that was originally the area SoCal Gas HQ. They worked well enough that I just left them in when we took over the property. However, as the rotors and valves need replacement we do with what we normally use; Hunter I-20s and Irritrol valves.

    Probably so plumbers can install them on the same zone as spray pop-ups without being embarassed by real pros in the irrigation business. :)
