Half-Inch Plastic Impact Sprinklers

Here is a compilation of a few different plastic impact sprinklers of various makes and models, all being an above-ground mounted head.
First up is an older Rain Bird P2-PJDA-C low pressure impact sprinkler that was made sometime in the late 1990s. These heads perform very well in the lower pressure range where most others fell short, although it does not do well above 45 PSI due to the light arm spring in it. They were one of the simplest part-circle impact designs made by Rain Bird, with very few moving parts and a one piece reverse lever that does not use a spring to trip. These sprinklers are rated for 2.2-4.7 GPM at 10-45 PSI with a range of 24-41 feet.
Next up is a rather unique impact made by Naan, known as the model 435 "Topaz" sprinkler. These were once sold in most hardware stores such as Ace Hardware back in the early 2000s, and are a more robust design than the typical cheap all-plastic impact sprinklers of the time. They are incredibly fast rotating sprinklers much like the cheaper models except they have better wear surfaces for a much longer life. The 435 was rated for 2.6-5.6 GPM at 15-65 PSI with a range of 34-48 feet.
Third in line is the once-popular Beta-II plastic impact sprinkler made by L.R. Nelson. These were once a very common sprinkler to find in use on many lawns across the country, mounted on many different types of hose-end sprinkler bases. They also came in a popup version during that same time period and were pretty popular in certain regions of the country. These Beta-IIs were of great quality for their time being made of all plastic components and aren't nearly as fast as most other plastic impacts out there. These were rated for 2.9-4.0 GPM at 30-60 PSI with a range of 36-43 feet.
Last (but not least!) is one that anyone else would have probably thrown out due to the broken arm but as you can see it still keeps on kicking. This is an older cheaper plastic impact sprinkler made by Lego/Water-Whiz back in the 1990s and early 2000s, which is a model 7220 with the blue fixed nozzle installed. These were once sold in most home improvement stores (mainly Lowe's) before Lego/Water-Whiz went out of business, and also came in a popup version known as the model 7329. These were rated for 2.0-3.4 GPM at 20-60 PSI with a range of 32-40 feet.

My grandparents' house had a system of Nelson pop-up Beta impact sprinklers. The system was fed by a 1-1/2 HP Sta-Rite pump from a lake. This was a number of years ago.

[@thesprinklerguy4875]

I've never seen any of these besides the beta two before, very cool 👍

[@starisgone]

i love it when they go BRRRRRRT

[@ryanfreitag1489]

I have probably over 50 NOS Nelson Beta 2 riser mounted impacts. In all 3 nozzle sizes. Green (1372), Red (1373), and Black (1374).

[@NelsonBigGunP200Fan]

I also had a lego with the spoon arm but it was a popup (underground) model. That thing ran at warp speed.

[@EscapeVelo]

I now have 7 Rainbird P2-PJDAs, 2 Naan 435s (mine have green accents), 1 Nelson Beta II, and 2 Lego Water Whiz 7225s. Cant wait to try them out. I have low water pressure, so the Beta II probably isnt going to perform well for me.

[@NelsonBigGunP200Fan]

that last impact reminds me of a mini-bird without the Tube PJ arm, rather its using an open ended arm.

[@NelsonBigGunP200Fan]

I used to have the P2PJDA-C and i had a few Beta 2's when i was younger.

[@NelsonBigGunP200Fan]

one of my beta II's had the spoon drive arm instead of the PJ

[@NelsonBigGunP200Fan]

if i ever get my own house, I want to have a sprinkler system with mostly older impacts. like 25 or 25PJ. Maybe a few buckners as well.

[@bluestingerborg]

Yeah. Same here man. They Nelson should bring back their old sprinklers back

[@spicypeppers2019]

Is the first Rain Bird still in production? It seems to work well.

[@murrfarms]

Unfortunately it is no longer in production - the current "P5R" model sprinkler is more or less what took the place of these old P2's. I also really liked the older ones because they would still work on the slightest trickle of a water stream, meaning they were very useful and worked great on low pressure sprinkler systems where other heads wouldn't work at all. The newer ones (P5R) do work "okay-ish" at low pressure but not quite like these old ones did.

[@spicypeppers2019]

murrfarms okay. Thanks for the reply!

[@heroknaderi]

I enjoyed it very cool 😎

[@salifdieme5863]

Hello. Your video is very interesting. I do not speak english very well. I would like to know the maximum radius of each sprinkler please. thank you very much

[@Snowcube]

The last one isn't the same Lego that makes the building sets, is it?

[@NIFA07]

I'm not too sure. My guess would be no, but who knows?

[@rajupavhane8304]

Nice video

[@bluebird2351]

Kindly tell me how many bar (pressure) required for operating

[@beingsneaky]

Its in the discretion of the video. But listed as psi.

[@thienanxa5818]

I thought it was a doom soundtrack at the beginning.

[@solarsolar8535]

So cool

[@MRIDNETGUY2004]

Murf I gotta show you my sprinkler system at my house it's under ground we have a raid bird system

[@aashayen6356]

Is it good for home lawn ????

[@tejonsolo7532]

Donde lo puedo comprar porfavor

[@celmacarla4864]

Very goooood!

[@tymier_1635]

I think that's enough water the grass flooded

[@BioSoftStudios]

1:58 i miss the nelson beta 2s, too bad i had to buy a knockoff version since those are the only ones available

[@BioSoftStudios]

Update: I finally found a beta 2 and bought it off ebay along with 2 other nelson sprinklers

[@NICK-zi7yp]

Where can i buy this

[@Raza-VLOGSUK]

Nice 👍

[@jackiespringer4469]

What kind of impact was the 2nd one

[@murrfarms]

That one is a Naan 435. I believe the manufacturer discontinued that model quite some time ago, though I have noticed a few of them for sale on eBay recently.

[@NIFA07]

@@murrfarms It's been so long since I commented that. I was scrolling through the comments and came across it. I was like 8.
