converting a sprinkler to drip for my beds

Post  sheisaeval on 4/23/2013, 1:31 pm

There's lots of information about how to convert a sprinker head to drip.

We bought a manifold - something like this but not the exact one http://www.amazon.com/Orbit-Adjustable-8-Port-Irrigation-Manifold/dp/B00004S26U but I'm not sure if I also need something else?

I'm planning to remove the current sprinkler head and replace with this, would that work, or would I need something else? We also got a riser but it's pretty much a tube.

Also, we're bought a coil of 1/4 inch microtubing and we're planning to connect that to the manifold and then poke holes where the plants need the water. Do we also need emitters or just poked holes in the tubing should work by itself?

So pretty much I'm asking if we need anything else other than the manifold, the microtubing, and something to poke the holes. We are also planning to cap off the other heads, what do we need for that?

Thanks!

Unless you've got the single riser on it's own sprinkler circuit, it turns out fairly problematic. Odds are you're sprinklers are on timers and run daily or every 1-2 days for 10-15 minutes, maybe less. Sorry, missed the cap off other heads, that's easy, just get a riser cap and teflon tape.

If you're using plain microtubing and then pin poking holes you'll have spray issues unless you crank the port to a low GPH setting. Once you set the port to a low GPH, then you'll have uneven watering from the microtube because you won't maintain the necessary pressure.

If you use the microdrip tubing, the flow rates are REALLY low like 1/2GPH.

You may have your best luck converting to a 1/2" polytube connector and then using pressure compensating drips were needed on short microtube extenders.

I don't see inline pressure compensating drips, but if you can find them, I'd go with the head you've got and use those.

I run a lot of my flower pots off 1/4" tubing with emitters from my sprinkler system. In the past, I had my irrigation guy adapt them and the lines come from under ground. I just found some Orbit adapters that screws on the riser tubing beneath the spray nozzle that has an output for one 1/4" tubing.

They also have one with four outputs

This way I dont lose the irrigation to the part of my lawn or shrubbery that it was intended for. I dont know yet how well they work with drip tubing, but it's been fine with most emitters and micro sprays
