Review: They are just emitters. Why do they need a review… - I like to use these emitters in my hair. They really do look nice and are way better than hair ties. I guess they also work great for my landscape.
Review: Easy to Install - work consistently well - I had another brand of red emitters that I was trying to use. Then I got a couple bags of these and the contrast was extreme. Each time those failed, these worked. They were also much easier to install. One of the things I appreciate is that the emitter is slightly off-center - this provides a large flat area to the side of the emitter top that lets me get pliers onto and makes popping the emitter in place much easier.

## Features

- 2.0 gallon per hour pressure-compensating emitter delivers same uniform flow rate from beginning to end of tubing runs

- Large water passages and self-flushing action help prevent clogging
- Constructed of highly durable UV and chemical-resistant materials to assure long life

## Questions & Answers

**Q: I have one 1/4" tube weaving in line for my hedge....do these work in-line with the 1/4" tubing to spot water exactly where needed??**
A: Yes, they work "in line" because they are pressure compensating. Be aware that they best work between 15 and 35 PSI, secondly @ 30 PSI and 30ft long, a 1/4 in line will have a flow of about 15 to 20 gallon per hour, hence you cannot put 50 drippers on the same 1/4 line (50 x 0.5 GPH = 25 GPH. You are then above the Max flow) If you need long lines of 0.5 GPH, look for "perforated tape @ 0.5 GPH" If you can't find here, ask me for the link. If you have "dirty water" I would then recommend Antelco drippers, because they are cleanable, The RainBird ones are not.I hope it helps Good luck

**Q: Now that i have these which way do i install them? if i put the red part into 1/4 tube get drips,  black end into tube a stream what is  2gph**
A: 2 gph is the flow rate. It stands for 2 gallons per hour.
Insert the black pointed tip into your 1/4" tubing, and the water comes out the opening in the red side.

**Q: I can't find detailed info on this model on Rainbird's site.  What is the appropriate water pressure range for these emitters?**
A: Because of their pressure compensating design, you get the same amount of water using pressure ranges from 15 to 50 psi. Generally speaking, we usually recommend that you use a pressure regulator set at 30 psi in most drip applications where 1/4" tubing and fittings are involved. Excess pressure can cause the smaller fittings to come loose from the main line. Thanks for the question, and if we can be of further assistance, please give us a call 208-336-3747

**Q: I see red and green drips 2gph.what is the difference?**
A: Red is GPM, Black is 1 and  Blue is 1/2 GPM

### ⭐⭐⭐⭐⭐ Easy to Install - work consistently well
*by M***N on July 5, 2025*

I had another brand of red emitters that I was trying to use. Then I got a couple bags of these and the contrast was extreme. Each time those failed, these worked. They were also much easier to install.

### ⭐⭐⭐⭐⭐ There is a specific way to install these emitters
*by D***N on June 5, 2020*

I purchased .5 gph emitters for a very large project to convert my 1800 series sprinkler heads to drip systems. I live in San Antonio, Texas and my water bill was out of control. I bought the Rain Bird sprinkler caps (1800CAPS Spray Head Cap for 1800 Series Sprinklers) to close off the sprinklers so I didn't have to remove them. I bought the Rain Bird Drip Irrigation Conversion Kit (Model #RCKIT-1PS), at Lowes, and used one sprinkler for the conversion kit. I have over 27 sprinkler zones with 500 sprinkler heads to cap for my many plant beds. Also, I have very high water pressure. The local water company will give rebates for the conversion but require the .5 gph emitters. These emitters are pressure compensating and have to be installed in a specific manner. The black pointed tip has to be connected to the half inch or quarter inch tubing with the blue tip emitting the water. If you use the blue tip in the tubing, water will not come out. It is one way directional. I've had a few fail even when installed correctly. I've used the non-water pressure compensating Rain Drip .5 gph BUE05 and it doesn't matter which end is inserted into the tubing. Water flows either way. I've read the reviews about the inconsistent flow rates. I haven't experienced it but it may be because my water pressure is so high. Not sure. So far mine are working properly but I keep a close eye on my plants to see if .5 gph is sufficient for the plant's needs. The wood stakes & barbed wire around some plants in the plant bed photo (3rd photo) are my creation to keep wild hogs from digging up my newly planted plants. It works very well.
