Raindrip PC8050B 2 GPH Pressure Compensating Drippers, Drip Irrigation Emitters for Drip Irrigation Gardening System, Maintains Constant Water Flow, 50-Pack, Green

These work perfect for my vegetable garden. Unless I change the set up or spots of my plants, these last for multiple years. I only ever really buy these when I change the set up or expand. Definitely get a puncher to help with getting them into the hose to save your thumbs but they haven’t seemed to get clogged and the have a consistent drip. This year we moved our garden but I was able to pull the old drips out of the old hose which saved me from having to buy all new ones.

These irrigation emitters work very well, I’ve installed nearly 100 of them and have had no problems.

I have come to like this product, as well as the 1 GPH and 2 GPH equivalents - but despite the description, I don't think it is pressure compensating and so I think they should update the description. I came to doubt that after dissection revealed no moving diaphragm that I could recognize, only a tortuous path for slowing water. A few experiments suggest flow rate varies more or less linearly with pressure, producing advertised rate at about 25-30 psi (about 2 bar). In case my definition is wrong, let me say I rightly or wrongly expect pressure compensation to indicate a highly non-linear flow vs pressure relationship, since I would expect some mechanism to lower resistance in response to flow rate drop, which I did not see. Although apparent lack of pressure compensation took me by surprise, I actually prefer this because it lets me use them in series and parallel networks to achieve whatever I want. But don't worry about all that if you aren't familiar with those concepts (e.g. maybe from resistor networks in electronics) - I think anyone would be happy as long as you have a good 25-30psi regulator, as long as you arrange for total flow to be within spec for that regulator, and as long as you don't have more than a few meters of elevation change downstream of the regulator. (If you don't mind some math, larger elevation change is also fine so long as you account for 15psi (1 bar) change for every 10 meters of elevation change, and then derate advertised flow accordingly.) (Btw, 1 GPH is roughly 1ml/sec, which makes the math way easier.)

The bad: They break if you step on them or drop something heavy on one. The good: They are amazingly consistent compared with some other adapters I tried. I use the 1/2 gallon per hour adapters. I'm up to about 150. I use 30 PSI pressure regulators and plug the drippers directly in 1/2 inch lines. Then I use 1/4" tubing to deliver the water to the individual plants. This arrangement keeps the 1/4" tubing pressure at 0. I like the 1/2 gallon per hour because it lets me set the timer to a reasonable length of time (I still have my flower box timers set to 3m per 24h, which is too short to control.) These are operating in a near desert environment with temps at or above 100F, and many are in direct sunlight. They are holding up fine so far.

Bought this emitter to irrigate six container plants with an aquarium pump. This emitter is great just a constant drip. Just wanted to add the working pressure on this emitter is 15psi so if you use too much pressure it probably will not work correctly. Use a pressure regulator.

Was thrilled with the price and delivery. Thought we had some defective pieces. Wrote customer support and got a polite and detailed response. They were very concerned and want feedback on our success. Our water pressure was too high, we thought the control unit and the drippers controlled pressure, do we reduced the flow into the system. All seems to be good. Will continue to monitor, but very impressed. Will buy again.

Out of two 50 packs (100 emitters) I struggled to get 7 to function correctly. I spent an entire day diagnosing an issue I had with these emitters putting out streams of water rather than drip emitting. There’s nothing else wrong with them, but that is huge. A huge waste of time and money. I’m replacing these with Netafim Woodpecker Jrs, 100 emitters for $30. I have 30 asparagus crowns and in row 1 with 7 crowns I went through 4 emitters to get a good one on my first plant in the row. I went through 7 emitters to get to a good one on my 3rd plant in the row and gave up on my second to last plant after trying 13 emitters. I am not joking. I spent the entire day calculating my GPM, reducing water feed pressure above the timer. Tested my 3 pressure regulators and filters. Cleaned lines. Pinched off and isolated other lines on the zone. The problem kept following the emitters when swapped for good functional ones. My two 50 packs are dated April 2025 and June 2025. That a full year from when I received them. I don’t know if it’s the brand, the seller, or Amazon in quality of valve material or if they are being stored in a way that’s damaging them. But I’m giving up on these and the brand entirely after this. I’m of the understanding that the Netafim’s are the Snap-On of irrigation PC emitters that a commercial grower would use. At $0.03 per emitter I’ll take my chances there even if I don’t use all 100.

I purchased these 1/2 gph emitters to use in my wife's potted plants that are adjacent to her raised beds that use tape irrigation that drip at basically the same rate. These emitters allow a balanced automated watering system since their drip rate is basically the same as the drip tape used in the beds. And in general, for the ones that worked, I was very satisfied with them. However, 7 out of 50 failed to drip properly and generally just emitted a steady stream like there was no flow resistance at all. Since I had already installed most of the emitters while discovering which ones failed, it did not make sense to send them all back for a refund/replacement.....also since it is likely that each batch will have a certain percentage of failures, so getting another set will just have similar problems. So to me, they were cheap enough that I just kept this batch. But I of course don't like that I have to eat the 14% failure rate in my costs.

Tienen demasiada variabilidad en flujo

The produce itself was great However 45$ was to much for one package of 50. The ad clearly states 3 pks of 50.

Excellent product, delivers exactly 2 gph straight to the plant thereby avoiding any waste water consumption

I love the price. Way cheaper than antelco. I would recommend it.
