RaindripPC4050B 1 GPH Pressure Compensating Drippers, Drip Irrigation Emitters for Drip Irrigation Gardening System, Maintains Constant Water Flow, 50-Pack, Black

Great drippers for my flowers and garden. The 1 gpm flow rate fits my watering schedule perfectly. Easily installs into drip line for a tight fit. I can add several of these on a single distribution line for multiple pots. Great value for the money!

The best drippers for garden drip irrigation. I one per 10 inch flower pot. Also use 1 per small plant in garden. Easily plugs into 1/2 inch main drip hoses or into 1/4 inch tubing ends for runs from 1/2 inch main drip line.

These are doing the job as expected. Easy to install and don't clog.

I've gotten two packages of these drippers. The first was an Amazon return and they worked as intended. For one gallon an hour you should see a drop every few seconds. I ordered the second set and immediately I could tell something was wrong. All of them just spray water out. At first I thought it may be a pressure issue as I didn't intially have a pressure reducer hooked up and they were at the ends of the lines (due to the fact I worked outwards and had to order more) but with a 25psi reducer installed the flow was the same. I used a measuring cup to determine they're emitting anywhere from 3-4 gallons an hour. This could easily swamp and root rot a plant in a couple weeks. Nevermind your water bill will be a lot higher than you expected. I examined the new drippers and they are inconsistent with the old ones. The front of the genuine drippers reads RAIN DRIPPER, the defective ones read RAIN DRPPER, the I is missing. The defective ones are also more matte looking than the genuine ones. In the picture the defective dripper is on the left. If you get these and they're spraying water you could simply cut the timer to 15-20 minutes instead of an hour to get the same effect water wise. If you have different flow rate emitters this could be a problem. As I have good ones and bad ones I'm sending this set back to try again for a bag of legit ones.

I have used these for years, and I swear by them. They don't clog up easily, unless they're covered by dirt. I don't use anything else for slow watering.

These are some of the best drippers I have purchased. No clogs, consistent flow, and no failures.

No hesitation about brand or price when repeat buying these.

Huge disappointment!After adding 38 of these units to a garden drip bed, I found that 10 of the drippers shot a solid stream of water. Not drops, a solid stream.After replacing the bad drippers 2 of the replacements shot a solid stream.I can't recommend these to anyone.
