How can GPM ever be zero? If there is ANY water coming out, then there has to be some GPM. Answer: Flow-by is not the same as usage. GPM can only be determined by knowing your PSI, selected spray pattern, and nozzle choice. Here is a link to the Rainbird PDF that will give you the information you seek. http://www.rainbird.com/documents/turf/chart_MPRnozzles.pdf

If you go to the 'info and guides' section of this webpage under 'specifications', you can click a link for a Rainbird PDF. There, all the details are specified. I believe this model is 0.1 gpm if over 8PSI.

This model has a flow-by: 0 at 8 psi (0.6 bar) or greater;0.1 gpm (0.02 m3/h; 0.006 l/s) otherwise.

Customer Reviews

Rated 2.9 out of 5 by 7 reviewers.
Rated 3.0 out of 5.0 by 1804 Adjustable Spray heads I am not pleased with Home depot how they gave me the mixed product. Some adjustable and some are not. September 15, 2015
Rated 5.0 out of 5.0 by Good Quality Sprinkler Head I've replaced several Hunter pop up sprinkler heads on my property with Rain Bird heads. In my observation, the Rain Birds work reliably and have a finer and more uniform spray pattern. The spray pattern of the old heads seemed random and uneven. I've also replaced a number of poorly-performing nozzles (from other brands) with Rain Bird and have consistently noticed an improvement in spray quality. Rain Bird is my go-to sprinkler brand. July 5, 2015
Rated 1.0 out of 5.0 by Poor product quality Researched 4" pop up irrigation heads, didn't want to go online since it was my first time replacing existing Nelson heads. I went with the Rain Bird reputation for good quality products, liked the adjustable nozzle to take out the guess work with the 15 heads I replaced. I had about half of the 1800 series leaked, in between the nozzle seams, some didn't seat back on the top causing residual water to continue leaking out. Some of the heads didn’t have a consistent stream but dripped on the edge when fully engaged. I called Rain Bird about my unfavorable experience. The 1800 Professional series were very pricey compared to stretching out a couple more dollars for other high quality brands. October 10, 2012
Rated 1.0 out of 5.0 by Frustrating These struggle to pop up and spray water everywhere in the process. The pattern is difficult to adjust and the range/distance adjustment doesn't appear to work. Save yourself the trouble and buy the Hunter brand instead. September 13, 2014
Rated 4.0 out of 5.0 by good product! Easy to adjust,products are not bad at all.Good for the do it yourself project and prices are comparable to distributors. July 4, 2014
Rated 1.0 out of 5.0 by save more money, don't buy these. I'm in the same boat as the above review, these are more of a controlled water hemmorage. I am in the process of upgrading to a different brand of rotator nozzles, higher price, but they will pay for the difference in less than a year factoring in water usage. April 16, 2013
Rated 5.0 out of 5.0 by Used with gear driven rotors these are perfect for covering smaller areas. These sprayers compliment the gear driven rotors filling in smaller or irregular shaped areas and walk ways. June 26, 2013
