If you are looking for no-clog drip emitters, the Non-Plugging Emitter for Drip Irrigation from DripWorks are reliable non-clogging emitters in a maintained system for your irrigation needs.
Sold in convenient, economical 10-packs, these emitters may solve your clogging problem if you are using a very dirty water supply for irrigating, such as from a pond or an irrigation ditch, and your fine screens clog quickly. Just use a coarse-screen filter (30 to 50 mesh) for large particles and the Non-Plugging Emitter will pass particles that would plug almost any other drip emitter.
This special emitter has two diaphragms inside with six small openings. When particles block the diaphragm openings, pressure develops and stretches the opening, forcing the particle through it. The opening then returns to its normal size.
- A minimum of 15 psi is required for these emitters to work properly.
- Use at the end of 1/4" tubing or installed directly in the mainline.
- Will emit 1 GPH at 20 psi.
I've had it with flag emitters and pressure compensating emmiters, I used to spend a portion of every Monday just checking to see if there clogged.
