Qualine P50 1/2 in sprinkler

works well
This sprinkler works well for my low pressure gravity flow irrigation. I still have to use my pump when nearby fields are drawing extra pressure from my system, but the sprinkler so far is performing like I need it to. Well made for the money, Thank You!

So far, so good.
I use them for pasture irrigation. I bought ten as a trial. I have three in place replacing Orbit sprinklers that stopped turning. The new ones are easy to adjust and put out a lot of water.

Absolutely impressed with these head's, They are so fast and the water coverage is amazing. Will be ordering 6 more for the front yard. Our wonky setup we have to turn them on individually by hand and you better be a good sprinter! Lol There fast.

Old standby, been using for years
Use for pasture irrigation. I have higher end sprinklers but over the years these have been a back up and have always produced for me. A removable nozzle for cleaning would be even better. Over all they work great for the value.

Removable Nozzle????
Have low pressure source of water from open resivour. Needless to say things get past my screening and periodic plugging occurs. Current product description states nozzle is removable for cleaning. I haven't found a way to remove it. Otherwise performance is great even at my low pressure.

These were recommended for 15 psi or higher systems. My system is 14 psi, and so far, they work very well, and at a great price! They are light plastic, and appear like they can be easily broken. These were a trial, and when I replace them, I will see if SprinklerWarehouse has some low pressure sprinklers that are much more durable.

how many gpm?
A shopper on Feb 6, 2012
BEST ANSWER: Can't answer how many gpm they are but I can tell you I water 60foot wide lawn and they work fine. However if you have dirty water (like irrigation) they get dirty and stop rotating.
will these heads fit a normal garden hose coupling?
fred p on Oct 8, 2015
Are these sprinkler heads for low psi over 60?
A shopper on Mar 15, 2014
BEST ANSWER: I am not sure. I used them on an irrigation system from Lake Sinclair in central GA. My father put the system in and he is deceased. These springler heads are great! You can adjust the spray from low to high. Our system had 6 different areas to water with quite a few sprinkler heads on each system. I hope this helps.
What is the minimum and maximum flow rate?
SUPOL K on Dec 24, 2018
BEST ANSWER: Well I cannot answer this with a direct answer, but I do have experience. I am on a gravity irrigation line that provides about 22 gal per minute on a 1inch line. with one of these sprinklers I can have a good 50ft diameter circle and with 2 or 3 it drops down to about 40 ft. I have run up to 5 and it still goes round but at maybe 25 ft. I have never measured my pressure. This is trial and error. I replace the sprinklers every 1-2 years depending on how badly they gum up or wear. I really like these, best performance I have found for my system least maintenance. Trial and error for 15 years and I like these best. Hope this helps.
can i convert pop up sprinkler to an oscillating one?
A shopper on Apr 16, 2016
BEST ANSWER: You would have to do some conversion depending on what you have in the ground. But yes. I would do one to see what it would take but yes it could be done. My application is on my small farm and I have raisers from the ground with the top threaded to except the impact sprinkler
The chart indicate 30 ft radius at 15 psi. My question: BUT the radius of spray should be about 25 ft at about 15 degree rotation, water output not a problem.

Can the above ratings be accomplished by reducing from 15 psi ?
cesar d on Nov 18, 2013
BEST ANSWER: I get 40 plus out of these sprinkler heads at 25 psi. I do not think you would get 25 feet under 15 psi some of my ends do not get very good distance if I drop under 20 psi
cesar d on Nov 18, 2013
BEST ANSWER: will depend on the number of sprinkler heads on that particular zone of your system. Yes I do have several of these heads that can easily spray that distance, once you get out that far you need more of a stream rather than a droplet spray. I prefer the droplet to have even coverage within the spray zone. Also I have found the larger area I attempt to spray, wind will play a major role in coverage. One of my systems have 19 zones over a 2 acre field. All heads are the Aqualine P50's. They work great at a 20" spacing, and most are set for full circle to allow overlapping of zones. As you can tell from my notes that was a considerable number of these sprinkler heads, and I have had no issues with a single one. They are easy to configure and can handle slightly higher than normal PSI if you have it. Hope this will help you.
I'am on well would like plastic pulsating sprinkler with spike?
A shopper on Jul 29, 2018
BEST ANSWER: I use this sprinkler on my septic system. Seems to work ok.
will the Aqualine P50 work at 50-70 psi?
Is there any problem with them blowing apart?
Tom S on Mar 27, 2018
BEST ANSWER: They should be fine.Enter
when will you get this item.P50 1/2 in. MPT Plastic Adj. Impact Sprinkler w/ 10-64 Nozzle ??
eduardo t on Oct 27, 2017
BEST ANSWER: I have used many P50 1/2 in. 10-64 impact sprinklers with excellent results. Like all plastic impacts a few get sticky, but no more so than more expensive ones. My application is pond water fed.
What is a 10 - 64 nozzle? I need some with a nozzle size of about 2.5mm diameter is this possible?
Michael B on Sep 3, 2012
BEST ANSWER: have six impulse sprinklers and when pressure gets to 30 psi sprinklers stop working.
I need smaller psi per sprinkler who do I know what will work.
Thanks for any help
Is the nozzle size 9/64 or 10/64 and are different size nozzles available?
A shopper on Mar 13, 2018
I have 2 Toro impact sprinkers will this part fit? I do not want to replace the entire can just this part.
