Multiple Micro Sprays using 1/4" line???

Posted: 2 years ago Quote
Hi all - I have a question about adding Micro Sprays to my existing flowerbeds.  I currently have a 1/2 drip line around the perimeter of the yard, with 1/4" tubing coming off in different places to feed my .5GPH drippers.  This has worked ok for me for a few years, but the extreme TX summers still take a toll on my shrubs and flowers.  I am thinking about adding a few Micro Misters to the mix...

Will I get proper performance if I pull a 1/4" line off my existing PVC sprinkler line, and using 1/4" tees to split the line, run 4 or 5 full circle misters (10' diameter)?

I can see that adding 1/2" tubing would be ideal, but I already have everything I need with 1/4".

Thanks for the input,

that should work fine....I have both drip and micro sprays coming off the 1/4 inch lines using t-adapters....the only thing you need to worry about is maintaining pressure throughout the system.....how many micro sprayers and drippers will you have total???

Thanks for your reply.  I am thinking about adding 4-5 half circle microsprays.  My intent would be to "blanket" the area with the sprays in addition to my existing .5GPH drippers.

My set-up:
*PVC line around perimeter of yard that leads to bubblers for watering my trees.  In heat of the summer, I run this line 2x per week for 25-30 minutes each run.  My trees are doing very well.
*1/2 drip tubing around perimeter of yard with several 1/4" runs branching off and leading to all of my shrubs and flowers with .5 GPH drippers.  All plants are low-medium water requirement.  In heat of summer, I run this line 2x per week for 75 minutes each run.

Adding micro-sprays:
*the .5 GPH drippers are doing OK.  They keep the plants alive, but throughout our brutal TX summer, the plants get very "fatigued".
*I am thinking that adding micro-sprays to the existing PVC line and running it for the same 25-30 minutes will add some benefit for my shrubs/flowers (in addition to the 75 min dripper run...)
*As the initial set-up and operation of the micro-sprays is fairly economical, it seems to be a "can't lose" idea...

Question:
*If I pull off the PVC line and reduce to 1/4", do I need to worry about reducing pressure?  The 1/4 line would be ~50-60' from the start of the PVC run.

Thanks for your input,

Hey Chris, before giving you a suggestion, I need to ask you a few questions: when you come off the PVC to run our 1/4" vinyl 50 to 60 feet do you want to attach just one of our Micro Spray Stake Assembly?  Also are you considering our single outlet Sprinkler Converter MLA-1RA1 or our 1 outlet in-line sprinkler Adapter MLA-SPR1?  
Thanks,

SST - the tentative plan...

I will tap into my existing PVC line ~50'-60' from its beginning.  From there, I will reduce to 1/4" and run ~30'-40' with some combo of 4-5 half-circle and quarter-circle sprays.

Looking a the products on the site, I think the breakdown will be:
*MLA-SPR1 coming off the PVC line to allow for continued tree watering on same cycle
*1/4" tubing, tees (MLT-TEE) and elbows (product #?) as needed.
*half-circles to be MLM-04 or MLM-44
*quarter-circles to be MLM-03 or MLM-03B

I have to do some final measuring based on the coverage of these sprays.  Going off judgment, I think these will work out fine.

Is there anything else I need to consider?

Thanks.

Thank you so much for explaining how you wanted to do this!  Using the 1/4" as a main line for several micro sprays will not be enough water.  You could probably run 2 and be ok but not several.  By using our 1/2" Poly as the main line then you could run up to 300ft and put up to 50 stake assemblies.  I am going to have our QC run a test in the next couple hours to see on a 100ft run of 1/4" vinyl how many of our stake assemblies will work.  My guess is 2 but there could be a chance 3 will run.  I will let you know what kind of results we get from our test.  For running our 1/2" poly from the PVC you have a couple of options to choose from on our web site.  If you look under “shop by category" click on "retrofit to pvc" and any of these 3 items will work.  
Thank you!
