We have about 120 wine grape vines in six 70ft. rows on our Michigan Upper Peninsula farm. They are a mix of 1, 2 and 3 yr. olds. It’s a hobby crop and we are trying to be cost and time efficient because we both work full time. Our first watering system was simply runs of soaker hose which proved unsatisfactory for a variety of reasons. We stumbled upon the Rain Bird drip irrigation system while wandering around at Menard’s. The 1/2″ main water line was quite reasonably priced at $30 something for 500 ft and the 1/4 tubing also at $8 for 100ft. I made my own ground staples out of 12ga vineyard wire) The whole system is well designed and very easy to install. Each of 120 vines required a certain amount of fiddling to get the tubing aimed where you want it but zip tying them to the stakes turned out to be the ticket. I am very impressed with the flexibility and the accurate delivery. We used these 1gph emitters, pierced directly into the main line and 1 foot of small tubing to aim the drip where it’s needed. A little bit of trial and error and we discovered some necessary alterations in our plan, but nothing that really set us back—it was all quite logical once we got started with the installation. The whole system is run through a standard digital water timer—the kind used in-line with a garden hose. Pushing the emitters into the hose requires some effort and I’m glad I bought the special tool made for it—but I also found it useful to make a backing block out of a chunk of 2×4 to make that job even easier. Just slide the block under the main hose into the channel and the hose is supported and kept from flattening out as you easily poke that little guy in—(on the end of the block I cut a slot to make pushing in the ground staples easier) see the pictures. On the whole I’m very satisfied and we plan to install another system for our 3 big raised bed gardens. I recommend this system for DIYers and anyone who’s a bit handy. Even on much smaller systems than mine, it seems like it would be cost effective in labor and water savings as well as over-all garden health.Note on useful life of system: My goal is to get at least 3 years out of this system, including taking it up each fall and reinstalling each spring. I’ll update this review as those experiences are accumulated. So far so good though at this beginning stage.

Good product
Good product, does an excellent job dispensing water.

Excellent drip emitters
We bought a new house and the backyard sprinkler system was broken beyond repair. Even with professional help, I was unable to locate the sprinkler valves for the back yard. So instead I set out to research and install my own drip irrigation to automate the watering process, mostly because I am way too lazy to water my backyard every other day. I chose the rainbird family of products because of the positive reviews and the plethora of options.I chose these particular drip emitters for the medium size trees and shrubs in my yard. I chose 1/2 in tubing for the systems backbone. Then 1/4 in tubing to run out to the individual plants, flowers, trees, shrubs… There are two ways you can install them. You can install them straight into the 1/2 in tubing, like I did. The other way is to install a 1/4 in coupler into the 1/2 in tubing, then run a 1/4 tube to the plant. Then connect the drip emitter at that end. I chose this configuration because some people complain about the water pressure pushing the emitter off the end of the tubing.+ Great price for a bag of them.+ Very easy to install them. Be sure to purchase and use the Rainbird special tool to punch the proper size hole in the tubing. Also use the Rainbird tool to insert the emitters into the tubing. I personally dislike special tools, but they are only a couple bucks each. I saved a ton of money by doing this project myself ($250 total cost), so to me it was worth it to get the specialized tools.+ Very happy with the performance so far.- Nothing thus far.I am very happy with the performance of these drip emitters so far. Some people have complained about them getting fouled with dirt. I don’t expect to have that issue. Ill update this review as necessary. Highly recommend!!!
