It would be alot easier to install a Rainbird PRS regulator into the solenoid and then be able to fine tune the zone. This would be easier than removing the 1800s, especially on sites that can have hundreds of 1800s.
Yes, this can be a good option. The downside is that the PRS DIAL requires inlet pressure to be a minimum of 15 psi higher than desired outlet pressure. So if you wanted to set it at 45psi, the incoming pressure must be a least 60psi for it to work correctly.
I have an honest question. The cost of these retro regulators is a buck or so more expensive than buying the rain bird 1800 4” with the 30 psi regulator built in from a wholesaler. Is this just atypical pricing on the rainbirds? My entire system is the 1800 4” so just replacing them all would be cheaper at the moment.
This could be possible, or at least it may depend on the retailer’s pricing. We sell the Retro-Regulator for $3.99ea (10 pack), which is below the direct cost of the Rain Bird 1804PRS before any markup (which we sell for $7.58). It is possible that someone is selling the 1804PRS at a loss, we see it everyday. The 4” pop-up size would be the closest equivalent, as the pressure regulated sprinklers get more expensive as the size increases (6”, 12”).
@@richsellskc you got it! Although, it is possible to just replace the 1800 inner workings with the PRS version and using the existing canister/body, however, you’ll be tossing out the new canister and the old inner workings.
@@Andy_Humphreyh the discount on the 10 pack makes sense. I was seeing individuals for $6 vs individual 1800s for $5. Bulk wins for the inserts though. @richsellskc no digging required in my soil. Either do like they said and pop the cap, or just spin the entire body off and gingerly pull them out and insert the new. Do this all the time as long as dimensions are the same (can’t do it if going from hunter bodies to rain bird for example). Now if they’re sunk an inch or 2 below the soil line this becomes more difficult, but mine are flush.
Oh, great question! Those are shorties…we don’t have any of the 2” to try, and if you send us your address, we’ll ship you a retro-regulator to try out, and report back.
Do these fit and work with Rainbird 3500 sprinklers? Also- Do they make Low Angle nozzels for the 3500 sprinklers? I've only found them for the 5000 series.
@peskypeet - unfortunately, these are only for pop-up Spray heads. Have you considered adding a pressure regulator to your zone valve? I do not believe there are low-angle nozzles for the 3500. May I ask what problem the low-angle nozzles would solve? Perhaps there is another option.
@@Andy_Humphrey I don't have a zone valve. I'm using a 3500 on a stand with a garden hose to water under a tree as I have no irrigation system. I use a simple oscillation sprinkler for the rest. I notice throw differences of a few feet at times no matter what sprinkler I use. I figured it was due to city water and the usage around me. I thought the regulators would stabilize the 3500 as with no wind it is at times hitting more of the sidewalk than I'd like. I wanted to try Low Angle nozzles on the 3500 to keep the stream out of the wind. It's already mounted on a very short stand to help but I get wind blowing from two different directions. Between the wind and I believe pressure differences at times the accuracy is all over the place. I wonder if there is a better choice of sprinkler that offers the throw and adjustment I'm looking for. I like to use a #1.5 nozzle in the 3500. The 1.5 nets me about 20+ feet and the #2 consistently reaches beyond where I need it.
@@peskypeet thanks for the info, that makes sense! You can add an inline regulator at the end of the hose, before it connects to the stand. It’s import to get a regulator for the correct flow rate. This link will direct you to a 42psi regulator designed for flow rates 0-4.4gpm. sprinklersupplystore.com/products/netafim-prv075lf42v2k-netafim-in-line-low-flow-pressure-regulator-42-psi For low angle, you might try a 3/4 rotor, like the RB 5000, or Hunter PGP or I-20. Actually, my preference would be the K-Rain RPS-75 Select, because it has built-in selectable nozzles (not low angle) but so darn easy. If interested - email/text us and I’ll send you a free sample. sprinklersupplystore.com/products/k-rain-60003-cv-rps-select-adjustable-arc-rotor-3-4-inlet
@@ascernas gotcha, thanks. The pressure regulators shown in the video are only for fixed spray heads and will not work in rotors like the the Saturn III. If you think high pressure is an issue for your zone/system, there are other options for you. You are welcome to schedule a virtual service call here: calendly.com/sprinklersupply/30min
