keep things simple. I tried to combine sprayers with emiters and it was a pain. The happiest and easiest was using the emitter tubing on a large flower bed. No punching holes, no tiny connections. Easier to find and not cut with a shovel. You just have to remember to look at the maximum row length of emiter tubing. For 12 inch spacing, thats about 250 feet if they are 1 gph emiters on 1/2 inch tubing. But if it's 1/4 inch emiter tubing, it's only like 30 ft.

Just remember to get hold down stakes when you loop things around

Remember, this is supplemental watering and it doesn't have to be perfect.

Thanks for the information.

Unfortunately, I don't think the irrigation is supplemental watering. Last summer we got 1/2 inch of rain in 2 months!

Some of the plants are far apart and I was thinking of using the 1/2 distribution tubing throughout the area to be irrigated and attaching the the 1/4 inch emitter tubing to the distribution tubing and running it around the bushes and plants.

The thing I like about the bubblers was that they are adjustable in how much water they put out.

All risers on one line must be either drippers or sprinklers. Can't combine the two because of the different required flow rates. But could cap off the offending riser.

Thanks Jean

We live in Portland too, so you understand the water situation here.

We are just converting one zone to drip and capping off the unneeded sprinklers. I still wonder if I can use the micro bubblers (made for drip irrigation) along with drip emitter tubing in one zone.

Karen, you can combine the micro bubblers and drip emitter tubing in one zone. Add up the flow rates of all the bubblers and emitters. The total shouldn't exceed the amount recommended for a zone with 1/2 inch tubing. That amount will vary depending on the size of the 1/2 tubing you have (there are several sizes of 1/2 inch tubing) . Your bubblers are adjustable so use the max for design purposes. If you have 5 bubblers at 10 gph that would be 50 gph. Then add in the emitter tubing. If you have 10 runs of emitter tubing and each run does 10 gph that would be 100 gph. Your total gph would be 150. You should be good up to about 200 gph

Thanks zeuspaul,

We will give it a try.
