Rain Bird "The Intelligent Use of Water" Review: It controls the water flow fair but take a long time to get the job done Review: I LOVE these little drip emitters! So easy to install, and accurate. I have over 30 plants on one 1/2” hose and the drip emitters either right off the main, or into 1/4 inch tubing, set on a timer automatic waterer. It cuts the work, and saves so much water! Where have these been all my life? Planning on doing my whole yard with this system as well as seedling tree lines for our little farm. Work smarter not harder ;) ## Features - 2.0 gallon per hour pressure-compensating emitter delivers same uniform flow rate from beginning to end of tubing runs - Slow watering rate allows soil to absorb water more completely in the root zones of plants - Self-piercing design; use with 1/4" Drip tubing or insert into 1/2" or larger Drip tubing - International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0049C5G18 | | Batteries Included? | No | | Color | Red/Black | | Customer Reviews | 4.6 4.6 out of 5 stars (3,287) | | Date First Available | 21 September 2023 | | Features | Pressure-compensating emitter, Self-piercing design | | Fit type | Self-piercing | | Global Trade Identification Number | 00077985007959 | | Is Discontinued By Manufacturer | No | | Item dimensions L x W x H | 16 x 16 x 27 millimeters | | Item model number | SW20-30PK | | Item weight | 0.02 Pounds | | Manufacturer | Rain Bird | | Material Type | Plastic | | Number of Items | 1 | | Number of pieces | 30 | | Number of sets | 1 | | Pattern | Dripper | | Power source | Pressure | | Product Dimensions | 1.6 x 1.6 x 2.71 cm; 7.03 g | | Set Name | 30 Pack | | Shape | Cylindrical | | Special features | Pressure-compensating emitter, Self-piercing design | | UPC | 077985007959 | | Volume capacity | 2 Gallon Per Hour | ## Product Details - **Brand:** Rain Bird - **Material:** Plastic - **Model name:** SW20-30PS - **Size:** 30-Pack - **Style:** Barbed ## Images ![Rain Bird - Image 1](https://m.media-amazon.com/images/I/61nKd38B7kL.jpg) ## 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.
