Поставляется с пятьюдесятью (50) капельницами с компенсацией давления ½ GPH; Цветовая маркировка для легкой идентификации расхода: красный – ½ галлона в час, идеально подходит для участков с тяжелой почвой/глиной; черный – 1 галлон в час, идеален для средних почв/суглинистых почв; зеленый — 2 галлона в час, идеально подходит для песчаной почвы. Эмиттеры с компенсацией давления ½ GPH предназначены для подачи стабильного и равномерного количества воды независимо от изменений давления или длины используемой трубки. Подает одинаковое количество воды независимо от того, где они расположены на линии и при различном давлении воды; Самоочищающийся эмиттер имеет турбулентную конструкцию потока, которая вымывает отложения, чтобы уменьшить засорение. Подходит для труб диаметром ¼ дюйма с внутренним диаметром 0,170 дюйма или перфорированным отверстием диаметром 0,170 дюйма; 1/2 GPH на эмиттер. Скорость потока остается постоянной при изменении давления воды на входе и положения по длине трубопровода; Идеально подходит для полива отдельных кустов и деревьев в ландшафте, а также растений в горшках и подвесных корзинах.

They work as stated, but not as good as another kind.

These do what they are supposed to, but I feel the other kind I have are putting down a bigger water circle. These were hard to install since the spout is in the center. The other ones I have are nearer to the outside edge and I can use my block of wood tool to push them in, which saves my hands and wrists from carpal tunnel issues. I haven't tested to see if they are putting out 0.5 gallons per hour. I have these attached to a 275 gallon tote gravity fed system ~7' in the air. They are on the last row of a 9 row system with a total of 180 emitters-all 0.5 gallon per hour emitters. These are in the same row as other emitters so I can see how the different ones operate.

Works great

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.

Excellent flow resistor (but is not pressure compensating)

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.)

Good Quality

Like the quality and reliably. Little more expensive, but worth it.

Worked as marketed, but more expensive

I prefer the larger size, but would have given 5 stars had it been $15/50 pieces. Also I wished they had 100 or 200 pieces bags at more reasonable price

Only works with a pressure regulator!

If you try to use these on a 1/4” line with the pressure coming from your home garden hose, you will have LEAKS! the pressure will be too great, since these drippers only let out drops at a time! You must regulate the pressure with device!

Worked well at first, then failed after 2 years

Bought these because the local Home Depot didn't have any 0.5 gph drippers for a newly installed system. During initial install had about 5-8% failure. After 2-2.5 years had roughly 80%+ failure (no, or very little, water dripping), replaced all of these 0.5 gph drippers with HD Dig brand. All higher gph drippers in this system are also HD Dig and some are failing, but at 5-10% rates (after 2 years). System has 25 psi pressure reducers and inline screens for debris. Also, each zone has a mix of drip rates, so it's not like there is a suspect zone with only 0.5 ghp drippers.

Works excellent.

When using in an alternate system it needs a pressure regulator 25psi or they will blow off and drench anything near it.
