rotor not working...where is problem?

Hi ya'all.

I came across this site and thought it most cool! I like doing many projects myself, and this site certainly will help me with my limited experience with irrigation systems.

Ok, I have rotors (pop up type) in my front and backyard, in the corners. The front yard I noticed last fall just before winterizing my system, the heads would not turn into an arc circle. I know it used to turn when I used it in the beginning of the season last year. I think this is a bad rotor? Would that be a good guess? (this rotor is in a corner and only throws in a 90 degree arc but I know its adjustable because the head can turn when I try to adjust it).

Second rotor is at the backyard in a corner also. This rotor has stopped popping up and it took a while for me to find it (hideous with grass over it).

I dug up these two rotors last Sunday. I wanted to find out the brand/model so I can order another set. BUT...I forgot which goes in the front and which goes in the back. The front yard is deeper than the backyard, but I cannot tell which rotor goes in the front and which goes in the back.

Here is the information I can get off the rotors:

Hunter PGP Model (I only see a G or maybe C...forgot)
Hunter PGP Model (I only see a H) on it besides

How do I select the nozzle size from www/sprinklerwarehouse.com? It mentions I need to know the pressure (PSI) at the sprinkler heads and Radius to get the nozzler size. To be honest with you, the irrigation system was already installed when I moved into the house.

My question (finally)...can I get some number off my rotors and order the exact replacement or equivalent? For example, I have Hunter PGP and it has an H on it...that is all I can get from it. How do I select the Hunter PGP rotors from www.sprinklerwarehouse.com?

Thanks! I appreciate, in advance, all of your help.<img src=icon_smile.gif border=0 align=middle>

Do you know how long the system has been in?
Pic's, maybe some more info on the rotors?

Do the tops of the PGP's have rubber or plastic tops? What size of nozzle are in them at the time? How many rotors are on a zone?

RVLI,
Thanks for answering my question.

I'll answer your questions.
How long has systembeen in?
I don't know, but the house is 6 years old and I've been living there almost 2 years. So the system could be anywhere from 3 years old to 6 years old.

Pics? Maybe some more info on rotors?
I can send/post pics. Let me take a picture and send to you or post here. Also I will look at the rotor and try to get more info. One thing I know, when the headspop up they are not stainless like some are listed in this web site.

Does tops of PGP have plastic or rubber caps? Plastic caps

What size of the nozzle are on them?
I don't know, but how can I tell? This was the reason why I posted this question.

How many rotors are on the zone?
I am not entirely sure, but I think it is at least 4, maybe 5 on this zone.

Thanks.

Sorry I haven't replied. I was gone since Wednesday.
To find the size of the nozzle, take the adjustment key if you have one, pull the rotor up and look at the nozzle and there should be a number on it. That is your nozzle size/number. You should be able to still get matched precipitation if you order new heads and install them.

But your backyard rotor could maybe not be because of the rotor....do all the other rotors in that zone work fine? Maybe you have something blocking the end of the line where that head is. Pending on where you live and if you can run your system this time of year or not, I would remove that rotor and try running that zone. If no water shoots out of where that rotor was, you may have something blocking it.

Again sorry for not responding as quickly..Hope this helps!!

ok her it is,roters dont last for ever.you expect 8to 10 years on most of your roters,the question on 1 respons was rubber or plastic tops.good question.rubber r newer,but those to came out about 10 years ago.if you have have plenty of water comming out of thehead.then its brobably time to change it.i like the pgp for thier distance and lastability.the main problem with them from my experience,is the leaky seals,they do make replacement seals.but in florida the sand is like sand paper on the shaft,so when you replace them in afew yearstheir bad again.ps im a rain-bird fan my self.i hope that helps.allen henderson
