## Description

Rain Bird ET63918-50 Drip Irrigation Pressure Compensating 1/2" (0.634" outside diameter) Emitter Tubing, 18" Emitter Spacing, 50' Roll, Brown. Rain Bird's emitter tubing works like a soaker hose; only better because it doesn’t clog and requires no maintenance! Once installed, your plants and landscaped areas are perpetually watered as intended. This rugged and flexible 1/2” Drip irrigation tubing waters plants uniformly with pre-installed pressure compensating .09 gallon-per-hour emitters spaced every 18". Rain Bird's pressure-compensating technology ensures all plants receive the same amount of water regardless of their position along the tubing run. Patented emitters are designed for clog-resistant flow to ensure even, reliable watering with zero maintenance. Industry leading flexibility allows tighter turns with fewer elbows for fast, easy installation. Professional-grade for unmatched resistance to chemicals, algae growth and UV damage. Unique Micro-Porous design creates an ultra-tight connection; tubing expands over fittings then shrinks making it almost impossible to remove without cutting. Designed to be used for both underground installation covered with dirt or mulch; or above ground where its brown coloring blends with natural colors.

## Questions & Answers

**Q: Can emitters be added between the weep holes if 18" is too far apart?   Thank you!**
A: I haven't done so, but I imagine it is possible if you clamp the two sides once you put the emitter in. Just be careful not to cut too closely to the weep holes. You won't be able to put the emitter in if you do so because a little plate extends about 1 1/2 inches out from each weep hole.

**Q: Is this a recycleable plastic when I tear it out?**
A: Yes But it’s made to reuse over and over and over I’ve had mine for over 10 years and it still works fine connections everything but yeah somewhere down the road down it is all recyclable

**Q: That I have to set a timer or the water has to be running all the time?**
A: I run it on my irrigation schedule as a landscape zone.  Running it all the time would be like leaving your hose on all the time.

**Q: I see I can add emitters but that defeats the underground advantage.  Can I simply put additional holes in the tubing to meet my spacing needs?**
A: I do not rec underground use. They have 1/4 inche tubing for side branches to individual plants. No do not cut holes. Insert emmiter. I like the big tool with blade and extraction for the emmiter. The red emmiter I believe are adjustable. The black ones come with .5 gal and 1 gal an hour. Buy both they are cheap. The 1/2 inche tubing is sold without holes. I have two berry plots about 20 ft apart. I use the plain tubing for the 20 ft to save water. For garden time varies due to weather and plants you have in garden. I have timer and set for every 3 days for 39-45 minutes. Look at your plants. If health continue. You do not want to soak the soil. Too much water is harmful. Some of the timers have rain sensors. The timer has to be exposed to rain. Mine aren’t. I just cut off faucet until soil  needs water. They systems are reliable. Rain bird has cut off valves you can put inline in case there are ares you want to turn off   Ex when planting garden and only have few plants in ground. Rain bird has connectors for anything you might want to do. They are not made for yard irrigation. Lawn mower could suck it up and cut. Mine is 3 years old and looks good as new. Again you need to heat end of tubing in very hot water to soften. This connection an easy job.
