Maximum number of Micro Spray Stake Assemblies is 50 per 300ft of 1/2" Poly Tubing if you have at least 40 psi at the faucet. Each Stake uses 10gph, so that is a total of 500gph if they are running at full pressure - meaning around 25 psi at the very last one. Typically if you tee at the faucet and run in 2 directions, you would have more water pressure at the ends of the line if you split the 300-foot run in 2 sections coming off the faucet.
Drippers: With a beginning water pressure of 25 psi, you can run 750ft of 1/2" poly using up to 500 of the .5 gph PC Drippers; 500ft of 1/2" poly using up to 250 of the 1gph PC Drippers; 250ft of our 1/2" Poly using up to 125 of the 2 gph PC Drippers; 240 ft of the 1/2" In Line Drip Tubing that has a 1gph PC Dripper every 12 inches; 12 runs of 33ft of our 1/4" In Line Drip Tubing that has a .5gph dripper every 12 inches running the lines off our 1/2" Poly; run 300ft of our 1/2" Poly using up to 40 to 45 of the Adjustable Drippers/Adjustable Dripper Stakes wide open max 10gph small spray. If they are turned down to just drip, then approx. 125 if they are dripping 2gph or less.
Drippers: Using 1/4" Vinyl as a main line versus using the 1/2" Poly Tubing, you can run up to 200ft of our 1/4" Vinyl with up to 25 of our 1/4" Tees with 25 of our .5gph PC Drippers.
It would be best if you could separate Drip and Micro because the Drip takes so long to disperse - like up to an hour - and the micro sprays usually only need around 20 - 30 minutes.
If you need to combine them, try to keep the total water around 500gph on a max 300ft run.
Choosing Micro Sprays OR Drippers To Water Landscapes
Micro Sprays benefits: See the spray pattern, easy to maintain, pre-assembled stakes, and easy to install - just snap a hole into 1/2" Poly, insert Flow Controller, thread in mister spray pattern of choice. Use on all types of soil and water just about any plant or tree you can think of. Very low water use of 10gph with great coverage of root zone.
Dripper Benefit: Better for clay soil types, very slow watering, hidden in most landscapes, no wind deflection.
(Little more effort to install, not pre-assembled, need to install several to cover the root zone.)
Using soil type to help in choosing Drip or Micro-Sprinklers to water plants, shrubs, trees, landscapes and gardens. Use this checklist below to help you decide which to use for these soil types:
Easy jar test to find your soil type:
- Fill a large jar 1/2 with soil, then fill rest with clean water.
- Shake well, then let sit 24 hours or so and take look at what type of soil you have.
