2 GPH Netafim Woodpecker Jr Pressure Compensating Dripper Emitters, 35-Pack Plus Hole Punch Tool and Goof Plugs for Drip Irrigation Systems

If you're looking for a reliable dripper that won't clog, this is it. I use them to water my trees. Be aware they have a built-in check valve that keeps them from operating at pressures under 10psi. This is what helps guarantee each plant receives the exact same amount of water, even on uneven terrain. If a Netafim dripper isn't emitting, like a previous review noted, it's likely a sign of pressure loss in that area of the irrigation system which activated the check valve… can happen if you run a really long line or load too many emitters along one line. A great feature most drippers don’t have. This is why the pros use Netafim.

Excellent performance. I think this is the company that invented drip irrigation. These don't clog.

So I know some reviews were saying "They don't work...", but I have not had trouble with flow. Installed one for a test on a regulated 30psi line and I measured the flow rate as being bang-on 1.98 Gal/Hr. I seriously question if people are installing these backwards, since they do have a check valve in them and reversing the flow direction is likely no bueno. However, I do have a gripe with these and my gripe is simple: **They don't have 1/4" barbs on both sides!!!** (Like every other drip emitter I've ever seen...) On the colored side the barb is a standard 1/4" drip line barb, but the black barb on these is a 1/8" hose barb. WTF!? Who does that??? No where in the product description was that stated and even going back and searching for it now that I know, the only indication I can find is a tiny little arrow in one of the pics deep in the gallery. This fact should be "front and center" info. As such these essentially don't work for what I needed...To the parts bin with you!

I have not tested all of the 35 that came in the pack, but the first five I tested are functionally equivalent to goof plugs. No water flows out of these, I can't event get air to pass through using my mouth like I can on any other netafim nozzle I've used. I contacted the seller about a week ago asking what the deal is and they never responded. Pure garbage.

These seem to clog much less than the rain brand.

I have only had them installed for about six weeks and all is well so far. Only time will tell. I like the color coded gpm.

emitters are what they are, the inclusion of the punch tool and end caps were a great plus for the price.

Used for drip system. Haven’t had time to install all of them.

Excellent.
