$6.49 /each

Frequently Bought Together

Product Overview

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 3.8 out of 5 by 15 reviewers.
Rated 5.0 out of 5.0 by Great tile for the $$ Got 3 pallets of 20x20 tile. .98 cents a sq.ft. Looks better than stuff for triple the cost. Delivered on time. Everyone in family loves color May 31, 2016
Rated 5.0 out of 5.0 by gets the job done The button drippers are easy to use. The only thing that is needed in addition to the drippers themselves is the thing that puts the hole in the main line. Poke the hole. Put the dripper in. Stand back and let it do its job. It's a pity, though, that the goof plugs were not also sold. Goof plugs would be an essential addition to the Landscaping Project April 26, 2016
Rated 1.0 out of 5.0 by Waste of time and Money... Won't stay connected to hose. Falls out Constantly. Don't Buy this... March 23, 2016
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 3.0 out of 5.0 by water dippers for my plants I like this product it work well on my plants sow far working well July 28, 2015
Rated 5.0 out of 5.0 by works great. I have drip irrigation for my patio garden and ran out of emitters. the button drippers are working great. May 20, 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.
