DIG's Button Drippers feature labyrinth water flow paths that allow for a consistent flow rate from each dripper at an incoming pressure of 15 to 25 psi with higher discharge at higher pressures and lower discharge at lower pressures. Chemical and clog resistant, the drippers are an economical choice for systems with short lengths of drip tubing. The drippers can be installed by punching a hole into the 1/2 in. drip tubing and snapping the barbed side of the dripper into the 1/2 in. drip tubing, or you can extend the drippers into the plants with 1/4 in. micro tubing or distribution tubing. We do not recommend extending 1/4 in. micro tubing from the button drip emitter nipple to the plant area. With this dripper we highly recommended adding a 3/4 in. screen filter to protect it from clogging and a 25 psi pressure regulator to lower the incoming pressure to the suggested operating pressure for a drip system.

  • Flow rate of 1 GPH operating pressure of 15 psi
  • Color code: black
  • High-quality materials ensure a long life
  • Large water passages help prevent clogging
  • Operating pressure range of 10 to 25 psi
  • Recommended filtration is 150 to 155 mesh

Rated 5.0 out of 5.0 by Excellent - needed this to replace 2 GPH dripper I've talked with a few people about the 2 GPH drippers and we agreed that they pop off. this means that you have gallons of wasted water because you probably don't notice it for several days, if at all. Home Depot doesn't know about this and DIG has never heard about it so I thought I was imaging it. But after talking with another customer, we agreed it was only the 2 GPH dipper and it occurs over the entire summer. so I cut out all my 2 GPH and replaced them with 1 GPH and 0.5 GPH and everything is working excellently.

Rated 4.0 out of 5.0 by Nice little dripper I had to run a drip line to several potted plants and just stuck these right in the middle. They work great. I was worried that the water wasn't going to reach the outer edges of the pot but it hasn't been a problem after a month. June 30, 2015

Rated 4.0 out of 5.0 by Great buy for your flowers and plants... Thank you Home Depot!! We purchased our entire ORBIT sprinkler system (40 ORBIT streamer sprinkler heads were used) from Home Depot a couple of years ago. We have 12 stations which includes 3 gardens with a drip system and also around the front and sides of our home. The 1 GPH button drippers work fine depending on the gallonage for the flowers you need. We also use the adjustable drippers for the larger plants. This is the 7th sprinkler system we have put in over the last 30 years. We could leave home for all summer and the lawn and plants would survive on their own thanks to the watering system.

Rated 2.0 out of 5.0 by Not very reliable Used about half of them on a line along tree set up to come on for a few hours in the night. woke up to find a trench left by on dripper that had its top blown off. August 6, 2014
Rated 1.0 out of 5.0 by Grumpy No two work the same. No quality control. If you want to save a little money, and have the time to do the job twice, this is the product for you. It's CHEAP and it's Cheap. You will have to order twice as many drippers as you need, because you will need to replace the ones that don't work. You will also need to order twice as many 1/4 in. Elbows, and T's as you need because they break. The 1/4 in. Feeder line is ridged and hard to work with, but if you have lots of time it will work. The 1/4 in. Barbed fittings, to attach to the 1/2 in. Main line leak, and are hard to work with. In my opinion after fighting with DIG drip irrigation products all summer, I wish I had paid a little more up front, and started with a better product, and only had to do it once. September 2, 2013
Rated 5.0 out of 5.0 by Good Product I use this all over my yard for my drop system, as well as in my garden's drip system. These things do a great job. They are easy to install and they are fairly durable. Make sure you have a pressure regulator on your drip system. If the pressure gets too high these things will pop out and you'll end up with a hole in your yard. June 17, 2014
