This is where most if not all irrigation designers fall short. Your irrigation system should be designed according to resident meter size. 5/8" meter 20gpm, 3/4" 30gpm & 1" 50gpm & psi. Many irrigation systems are tee'd off before the home,the home is usually regulated. In addition a 3/4" hose bib has a way smaller diameter than a 3/4" full port ball valve hose bib. Just food for thought.
I filled the 5 gallon bucket in .42 seconds, I don't know if I'm right I got 7 gallons, how many heads can I put? 3 or 4 ? I don't think I did it right.
One of the few videos I've seen that show you need to check your flow at the psi you are looking for. There can be a huge difference. You may get 20gpm wide open, but your psi is so low, your heads may only spray 5ft because you thought you could put 20 heads in 1 zone. Why these other "sprinkler" guys don't tell you that you need to see what your pressure is, is idiotic imo.
I'm planning to do 4 zones, 3 rotors per zone, I currently have 60 psi and 13.55 gpm. Do you think this will be enough pressure/gpm? Planned to use the DIY orbit system or something similar. What do you think?
Building a system on a mine site with 42 sprinklers each using 135 L/min. Still the exact same theory, only I have flow meters to help do the calculation/ measuring
Hi! Thanks for the video! I have a question if you could help me. I try to figure out the flow on my main line. Its pex 3/4 (7/8 OD) with 64 psi. I would like to connect my sprinklers heads on it but its hard to know the flow, I can find the pressure with pressure lost table but the flow is mestery since it depends on a lot of things... After that I need to take a % of that max flow to be able to get a 30 or 50 psi at the end... My garden faucet is a frost proof system with 1/2 pex line and it supply about 8 gpm max. So I want to add a splitter on the main line to have the best flow... thanks!
Hello Patrick, if you search for a pex flow chart online you should be able to find what you need. This video also might help you with your calculations: ruclips.net/video/Qbjn6KvZKjo/видео.html
Here’s what we want to know. What is the average secs to fill a 5 gallon bucket on a water system that is working correctly? Also what is the seconds to fill a bucket on a system that has really great volume such as 15 secs to fill a 5 gallon bucket
This'll work for a city water system with constant flow and pressure. What if you're on a shallow well system. How do you calculate, when the pump pressure constantly changes depending on faucet openings?
Sorry for the late response! This method is actually used on pumps/wells more than city water. Turn the faucet on until you maintain a consistent pressure. If it continues to fluctuate then close down the faucet until it eventually holds a a constant pressure and then do the test. Hope this helps!
@@ewingoutdoorsupply Could you guys do a short video showing how you test a bad producing well and how you would design a system around that. Maybe talk about when you would draw the line in not installing a system without holding tanks/ cisterns etc.?
@@benwilmarth5473 Thanks for the suggestion. If you need answers to questions regarding pumps, you can also call the Pump Pro Hotline at 1-844-PUMP-PRO for assistance.
Can someone please explain exactly why he partly closed the valve to get 30psi before doing the flow test? How does that simulate the pressure requirements for the heads?
Sorry for the late response. He used the ball valve to simulate having heads on the line. The heads restrict flow and create back pressure so the valve is used to create the same situation to get a more accurate flow calculation. Thanks for the question!
There's quite a bit of information needed in order to properly design an irrigation system. The available water flow at the source, sprinkler head and nozzle selection, how many zones will be needed, etc. This information is needed in order to determine the appropriate pipe size. Here's a couple of videos that will give you an idea of how to get started. Estimating zones: ruclips.net/video/Qj6MFG3kU9o/видео.html Calculating water flow: ruclips.net/video/eEfyFiOUeUA/видео.html
Good question Ruben! You can find that information in the manufacturers catalog. You will need to know what nozzle is being used and the system’s pressure. Check out this video for an example. m.ruclips.net/video/Qbjn6KvZKjo/видео.html
With all due respect, I don't get it, a contractor will do what the job calls for! Trying to measure accurate GPM. through a restriction is silly! no one in there right mind would run a sprinkler system off a hose bib.
I got 20+ more years experience than you, it doesn't make me right or you wrong! But if you can't comprehend the difference between a restrictive globe valve & a full opening valve you shoot yourself in the foot, Of course you can measure GPM flow rate through a restricted HB. if that's your supply. But what idiot would feed a sprinkler system off a HB? Information is available try Googling orifice flange calculations' & restriction. I've installed many in oil refineries industrial applications and space launch complexes.
You notice how you cant respond to my point, only change the subject? I talk flow rate, you talk "no contractor will" & "the spicket will work" " I’ve been a contractor for 33 years" "Now it's FPS flow rates"How about answering a few questions? Does a HB restrict GPM flow rates? Yes or No. Is there a flow rate difference between Globe & full opening valves? Yes or No? Why would a contractor with 33 years experience mickey mouse a sprinkler system off a hose bib?
You see what I mean? You changed the subject again. Can't answer simple questions! I wonder why you are afraid to debate. It's what Lib Democrats do when talking politics I.E. Change the subject, Ridicule etc.. Did you vote for Hilary Clinton ? Inquiring minds want to know. PS. I think I hold the record for being a champion Mickey Mouser. Have a good day Okay. Steve
Thanks for the comment Steve. To clarify. this video is not suggesting you run the sprinkler system off of a hose bib. It is a simple and commonly used method to determine if you have the flow you suspect. For instance, if you have a 5/8” meter and 60 psi static it is appropriate to think you will have 12-15 gpm. A bucket test is a preliminary test that can be used to verify this. Yes...the value you get from the hose bib will be a conservative number due to the restriction in the hose bib. A more accurate test would be to perform a flow calculation after the cross connection has been made.
Don't forget you lose 1-2 gpm through that faucet. Also, why not just use a toro gauge that has the flow gauge on it with a metered outlet? I use that and just add 1-2 GPM, dependant upon static pressure. Another thing, if you're on a well, this test is not valid until the tank is drained and the well has engaged. This is why it's probably best to leave this part of the job to a seasoned professional than to try and wing it as a homeowner. If you screw up the zone lines adding too many heads, you're already in too deep.

So I got 30 gallons per minute if I have 3/4 which I could use 12 heads 1800 that take 2.5 gallons?
One of the shortest, simplest and easy to follow videos in this topic. Thank you!
Glad it was helpful! Thanks for the comment!
Short, clear, and complete - thank you!
(oh and a clever device there - easy to make at home!)
Thanks for watching Brian!
I know this is 5 years old but this might have been the biggest help
Glad we could help!
This is great. Building one of these for next season.

This video covers the question of how many heads in a zone...

Distance from the farthest sprinkler to the pomp, pressure loss, how many elbows before each sprinkler... etc

Hose bibs have only a 3/8 diameter hole. To calculate GPM remove HB install a gate valve

Are these US gallons?
That is correct.
