Raindrip PC2050B Pressure Compensating Dripper, 50-Pack, Red/Black

Working

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.

These are basic plastic passthrough drip emitters. I deployed 20 emitters a couple of weeks ago and have had no functional issues so far. The drip rate appears reliable, although I haven't yet tested the specific rate yet to determine accuracy. The only thing that I have to fix is the emitters closest to the pump continuing to drop water when the pump shuts off, which I expect is a function of back pressure in the line rather than the emitter, but still something to consider and adjust for in order to avoid overwatering.Recommended. This emitters are a cost effective way of getting controlled water flow where needed and help make the process of automating watering easy.

Installed 100 of these in our vertical garden wall. Was able to get rid of all the adjustable manifolds, adjustable emitters, and additional valves I added to the overcomplicated setup. Installed these in 1/2 tubing and all 100 are dripping at the same rate. SO much easier. I've learned my lesson the hard way that pressure compensating emitters are the only way to go. These are great! Seller was also great to work with.

I bought these on two occasions: First time, two years ago. Second time was last year. I bought these Rainbird 1/2 GPH drippers on both occasions because I had a difficult time finding my go-to drippers made by Dig corp either on Amazon or at my local big orange box store. I incorrectly assumed a simple piece of plastic that is built to drip a slight trickle of water should not cause any problems, but I was wrong. The ones made by Dig corp (they are brown in color) typically lasted about 3 to 5 years before I have to replace them. I realize that Tucson Arizona water might not be among the purest in the country, so it's a given that you'll expect eventual failure with button drippers clogging up as evidenced by even the Dig branded ones. However, when I first bought this Raindrip brand they seemed to last a pretty good while before they started to gradually reduce the amount of water coming out, with eventual failure. This started happening after about 12 to 18 months. By the time I noticed this I had already made my second purchase of these on Amazon (I still have the second, brand new package, sealed and unused -- they are going straight into the trash now since it's too late to return them for a refund). So I did a bit more digging and found that Amazon sporadically has the Dig corp ones in the 1/2 GPH flow rate (again, the brown ones) version on sale, but by third-party vendors and at an outrageously bumped up price. I also did a bit more research and found them for sale where I used to buy them locally, and at a reasonable price, but I had to special order them online for in-store pickup. This is certainly not as convenient as buying them online on Amazon and getting them within a couple of days, but at least I can now return to using the brand I like that lasts a lot longer locally, albeit with a couple of week wait time before I can pick them up in the store. Interestingly, I also bought some Raindrip button drippers in the 1 GPH and 2 GPH flow rates and these are still going strong after a couple of years. I attribute that to them taking a longer time to eventually clog up due to hard water because of the higher flow rates and associated larger internal button dripper components. I'll keep an eye on them and see how long they last. In the mean time, I can safely say that I will never buy the Raindrip branded 1/2 GPH drippers and whole heartedly recommend others consider my experience. The other sizes are TBD as far as performance goes. I will, however, go back to buying Drip Corp branded 1/2 GPH (end even the other sizes) even if I have to wait a while to get them in the mail or pick them up locally. My preference is almost always to buy from Amazon, but when I can't get what I want at a close to reasonable price I'll take the long and winding road.

When using irrigation drippers in a string of hanging baskets, it is important to be using pressure controlled drippers. Otherwise, the baskets at the end may not get enough water. These worked perfectly.

Out of 11 I used yesterday, two are gushing out, one is putting too much water , and the remaining 8 are good. Not much to be proud of! The rest I guess I’ll find out.

A little more expensive than the cheapest drippers, but these work best without clogging.
