## Description

Product Description          Rain Bird 1804AP4PRS Pressure Regulating (PRS) Professional Pop-Up Sprinkler, Adjustable 0 - 360° Pattern, 3' - 4' Spray Distance, 4" Pop-up Height. High pressure in irrigation systems causes wasteful water loss through misting and over-spraying. Rain Bird’s patented PRS Pressure-Regulating Sprays eliminate this costly problem with up to a 50% water savings. Our built-in regulator maintains an ideal water pressure of 30 psi to maximize watering efficiency. Precise water-pressure ensures optimal nozzle performance and water distribution; even in windy conditions. Approved for sale/meets all pressure regulator legislation requirements in CA, CO, HI, VT, MA, ME, NY, OR, RI, WA, and Washington DC. Installed in parks and yards across the globe, Rain Bird's 1800 Series is the #1 commercial-grade irrigation spray head brand in the world. Chosen for its reliability, heavy-duty materials and versatility, the 1800 Series has first-rate quality built in for reliable operation and long life. Superior components and features make them the spray heads of choice for a wide variety of applications. This sprinkler’s Matched Precipitation Rate allows it to be used in any combination with other Rain Bird fixed and adjustable pattern sprays. Additional 1800 Series features include: Heavy-duty stainless-steel spring to assure flush retraction, every time. Exclusive co-molded wiper seal features an encased plastic "cage" to provide unmatched resistance to grit, pressure and the environment. Pressure-activated, multi-function seal design assures a positive seal without excess “flow-by” allowing more heads to be installed on the same valve. Tapered pop-up neck helps remove debris during retraction while a precision controlled flushing action also clears debris to assure positive stem retraction in all soil types. Two-piece ratchet mechanism on all models allows easy nozzle pattern alignment without tools and provides extra durability. All sprinkler components are removable from the top without special tools; providing for quick and easy flushing and maintenance. Spray Nozzle details: The preinstalled Adjustable Pattern Spray Nozzle is easily adjusted to the exact pattern required to ensure your landscape is precisely watered with minimal overspray waste. Ideal for odd-shaped corners and smaller grassy areas around sidewalks and driveways as well as flower beds or shrubs. The textured adjustment collar rotates to easily adjust spray pattern from 0° to 360°. Textured base and collar are easy to grip even when wet. A physical left edge indicator makes it easier to feel the fixed left edge of the pattern. Non-corrosive plastic and stainless-steel construction for long life. Simple stainless-steel top adjustment screw decreases or increases spray distance from 3' to 4'. "Captured" screw slot prevents screwdriver slippage during adjustment. White medium mesh filter screen protects nozzle from clogging and maintains precise radius adjustment. No tools needed to change nozzles. 1/2" inlet size.

## Questions & Answers

**Q: The item says it cannot be delivered to my address (in Indiana). Whay is that?**
A: My guess is that Rain Bird only ships their "Professional" models to their registered professional and retail suppliers.  I was able to get this model from a secondary supplier, not directly from Rain Bird.  Also there are non-pressure-regulating pop-up sprinklers which probably would be Ok for you since most sprinkler systems are located downstream of your house water pressure regulator and back flow preventer.

**Q: can this item be returned?**
A: Yes

**Q: How many gallons per minute?**
A: Depends upon setting of water release at head.

**Q: what's the supply fitting size , 1/2" or 3/4" ?**
A: 1/2inch pipe.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Product good but company attention to detail not so much
*by B***Y on May 24, 2025*

The item is a great product and is the measurements it says on the sprinkler itself. The product isn't the issue. Product is 5 stars but the attention to orders placed from the company, Max Warehouse,, is currently a 1 star. They sent me the wrong product twice in a row, same wrong product. The ones I ordered are 8-15' spray distance and they sent 4' spray distance, twice. Someone either isn't paying attention or something is shelved in the wrong place or both. Returns were easy and no fuss so 5 star for that but I shouldn't have to return it twice for same issue of wrong product sent. So, overall a 5 star for product RainBird, but a 3 for the company Max Warehouse. I just had them refund me the second time.

### ⭐⭐⭐⭐⭐ Fits the R-VAN rotary heads.
*by C***U on May 15, 2025*

Basic rainbird PRS sprinkler head. Writing this review primarily to help those of you thrifty fellas like me who tried to find out if this was compatible with the rotary water saving R-VAN rotary heads. The only info on this was some guy saying it doesn't fit the 12+ft heads due to the filter but he's wrong. It fits both the baby blue 8-14ft and khaki 13-18ft R-VAN heads. I can't confirm as I only use the blue and khaki for my landscape, but I'm sure it fits the other ones just fine as well. I got this to replace a faulty body, but re-used my khaki head on it.

### ⭐⭐⭐⭐⭐ Great for the price and lives up to the Rainbird quality.
*by M***S on June 9, 2025*

You can always trust the quality of Rainbird products. A piece of advice, if the sprinkler isn't function as expected, clean out the filter under the spray head. I learned that the hard way and now I clean all of mine once a year.
