Plugs directly into 1/2" line no problem

Using these in 2 6x12 raised bed gardens. Instead of using 1/4" tubing all of my emitters are plugged directly into the 1/2" line with NO problems at all. I have a 25psi regulator and backflow preventer on the inlet side of a Y connector and each bed connected to 1 leg of the Y. Pressure at the hose bib is 35-40psi however given the distance to the furthest bed I don't get the max distance but still enough flow to water the entire garden in 15-20 min. Edit: May 2019. I have now ordered and put to use over 400 of these emitters. Last year I had 2 6x12 raised beds and this year it is 5 4x12 and 10 4x4 raised bed. On the 4x12's I have 33 emitters and the 4x4 9. As others have said it takes a bit of work to get them the way you want them but the 30 min I spent doing that was time WELL SPENT!!! Once they are adjusted all is good unless the water pressure changes quite a bit.

These little guys are awesome!

These little guys are awesome! Adjust the water flow from a small drip to a 10" circle spray, you can even close off completely.

Good product

Works as designed

Hilario Castrejon

as could as the expensive brands

I recently planted vines on 90 ft of fence. The brand name drippers would have cost me $35. These work just as well and cost far less...... and I have many left over for the next project. Highly reccomend! Buy a lifetime supply now while they're still cheap !

Exactly as advertised, no issues

I don’t know why these had any bad reviews. I’ve had them installed for months and exposed to full Southern California sun all day everyday. No issues at all. Still all adjust perfectly and are just as good as the ones I bought locally for 10x the price. Great parts that do what they’re supposed to.

What a bargin.

Since I have raised beds with water lines I use a lot of these regulators. The work very well,and since you may get a bad one now and then, most work as they should.
