Well, that is,fairly open ended, those heads throwing father than you would like, is probably ok, usually the water at the end of the curtain is minimal, has a catchup test shown that your efficiency is low?
Sorry, should have mentioned that it’s either hitting my house or spraying on the driveway
Still working on the catch cup - was trying to get the spray patterns how I wanted them first
Trying to understand something - Hunter’s examples for ‘matched precipitation’ doesn’t seem to consider the increased radius of nozzles with higher flow
The article just says 1x flow for 90, 2x for 180, 4x for 360… except it doesn’t seem like it would be that simple since the radius is changing, right?
You have fairly old rotors if they use the red PGP nozzles. They should begin to wear out ovet time. Check if Hunter has a low angle nozzle option available for the red nozzles. How many rotors do you have? If not too many you can replace them with new PGPs that use the blue nozzles. For the new rotors they have free grey nozzle trees that are low angle. The low radius nozzles throw less further. If you are decreasing the radius by more than 25 percent try using MP Rotators that have so many radius configurations. Hope this helps a little.
You can try, but as I recall they are not compatible. Those PGPS only have a two year warranty from date of manufacture. Personally, I would complain to the contractor because it’s been at least four years since Hunter was selling the old style rotor. The good news is Hunter is very good about standing behind their products. Find out where he bought them and tell him he sold you old stock.
I just checked Hunters website. I was wrong. The blue nozzles will fit any PGP back as far as 1982. My memory sometimes fails. Sorry. So I would insert the PGP low,angle nozzles. They are grey. Look in the Hunter catalog for the correct part number. Any Hunter distributor can get or give them to you. Or call Hunters tech service group. Just make sure they don’t confuse the pgp ultra nozzles with regular pgp nozzles.
It doesn’t seem to me that it’s possible to do what it describes (with rotors, at least)
It seems to indicate that you can have a 90, 180 and 360 rotor, all with the same radius of throw
Am I understanding this correctly?
If so, it doesn’t seem like you can turn down the higher flow nozzles’ radii to equal the 90 rotor - as you can only reduce by 25% and even then, you get misting
Hmmm. Those larger nozzle sizes are for large yards and larger sized pipe. Try 3.0 for full circle, 1.5 for half and .75 for smaller yard. You are seeing unusual results. I have 9 rotors in my backyard all on one zone, but it’s 4,000 square feet and I have a 1.25 inch mainline.
