MBH4PKS Drip Irrigation Micro-Bubbler on Stake, 180° Half Circle Pattern, 0-3' Spray Distance, 4-Pack

These Rain Bird micro-bubblers were exactly what I needed to extend my existing drip system into a few new areas of the garden. The price was better than what I saw at my local Home Depot, and with Prime shipping, they showed up the next day—can’t beat that. Installation was a breeze. Just plug them into the 1/4” tubing, stake them where you want coverage, and adjust the flow as needed. They offer a nice, even 360° spray, and I was able to dial in just the right output for different plant zones. I especially like them for small fruit bushes and perennials that need consistent moisture but don’t love being soaked. They’re basic, but in the best way—no frills, no fuss, just solid performance. Great for anyone building out or tweaking a Rain Bird drip setup.

Since installing my drip system last year, I have continued to tinker with it to get the right amount of water to the right places. After finding these, I feel I have accomplished what I wanted to do. I have large flower beds, and had run emitter hose with spot emitters added. I kept adding emitters, but it still took forever to get a good deep watering. Not much really came out of the hose. It may be partly an issue with my water pressure. I added these, and instantly knew I had found the solution. Each micro-bubbler can be adjusted to control the distance it covers. If I had it to do over again, for my large beds where there are no rows or vacant areas, I would just run the solid hose, and add these every 5 feet or so. They set low enough that the water doesn't evaporate like with a regular sprinkler, but put out enough water that I can get a good soaking in a couple of hours. For areas where plants are further apart, the spot emitters work well, but these can also be adjusted for a low flow. I like them a lot! Update 6-2020: Four years later, these are still working great. I have lost a bubbler head or two; if you loosen them too much they can pop off the next time you turn the water on. I leave them out year around, through freezing weather, along with all of my rain drip line and emitters, and just hook up a hose and go every spring with no issues. I'm buying more for my expanded garden!

These work perfectly in the garden. Rainbird has never let me down in the many decades I've used their products. The spray is quite versatile and easily adjusted. Very easy installation.

I didn't read close enough, I was expecting a large bag of these but low and behold, right here in the description, four. Which means these are over a dollar a piece. What I did like about them in my large pots is the ability to keep them at the edge of the pot and not waste water because it only sprays 180 degrees. Other cheap brands spray at 360 so you lose water over the edge of the pot if you do not lean them back a bit. These also seem to be made better than the cheap ones.

We have several drip lines in our backyard and a puppy so we have had to replace a lot of drip lines and sprinklers and these are easy to use, replace, work well, easy to adjust, fit on the drip line easily, and for a great price to keep backups on hand. Thanks, Amazon!

Great product, great price and quick shipment!

I have several drip irrigation lines that I needed more control over the total water flow. These worked great. No issues and I'd order again.

I don't like the spray pattern being only 5 small streams of water.

We have configured all of our plants to be micro irrigated due to the high cost of water in our dry environment. These rain bird irrigation bubblers are perfect for water savings and effective irrigation. These are brand name quality parts.

Works great
