Very well done, and completely convinced me I need to save my money and hire a professional. I now know why the owner installed system on this property is so grossly inadequate!
OMG! I don't remember this being that confusing. Did my former home 20 years ago and it was very easy to understand and do. My dirt back yard looks fine the way it is. lol
I have been looking for an easily digestible way to understand this surprisingly complex topic. Bought a house with over 10k sqft of lawn using 18 sprinklers in total; Mixture of fixed, rotor and other, all on 2 zones/valves. I thought this was weird and you helped confirmed this. I live close to the county irrigation pump station and I must have insane pressure. This is gonna suck. 🚧😫🏗⛏😓
I installed a sprinkler system and it works like a charm, saved over 3,000 dollars , it’s just common sense, it’s not as complicated as this man makes it seem
You guys messed up a bit with the editing at about 6:00. You guys point out that the highest pressure loss recorded for a 3/4" meter is 15 psi at 30 gpm, however you guys point to the 5/8" psi loss.
I’ve been watching lots of residential irrigation videos and must say this is by far the best in both information and presentation! Thank you!!! However, That’s a lot of water just to irrigate a lawn. Plus winterize it for those few freezing temps in North Carolina. Maybe an irrigation system for my 4.5K sf lawn isn’t appropriate?
It’s not hard to winterizing a system. All you do is hook an air pump to the water pump on the system. Open all the zones, and spray out the system I tell nothing but air is coming out of the heads. I love doing irrigation work, came here to learn more about what my boss does designing systems. To help me better understand installs. So that one day I may start my own irrigation business with lawn care ,spring and fall clean ups, possible some hard scaping.
@@cscgamming And you have to be careful of the air pressure. Air pressure must not exceed 50 pounds per square inch (psi) during the blow out procedure. www.krain.com/winterize-your-sprinkler-system
Just a heads up... at 6:05, the red arrow points to the wrong 15.0 (in the column for 5/8" meter) which equates to 20 GPM (when the narrator says 30 GPM). Had me super-confused for a minute until I realized it.
Would also suggest that during initial site analysis, pre dedign, that you verify your max.rate of flow available at your source - especially on homes built pre WWII. Don't assume! I ve worked on homes with a max flow rate as low as 7 GPM.
@@noeeon9910 yes for planting areas! In lawns I used hunter PGJ sprinklers .75 gpm nozzles and lots more valves. It worked very well. Fortunately it was a small lawn.
@@noeeon9910 The other option could have been the newer subsurface drip polyline products available, but tons more trenching and too many gophers in my area! But I've used that in other low GPM, level areas, without gophers with sucess (so far...lol!).
@@melaniemackenzie8084 are you talking about regular Drip line like hunter PLD or rainbird copperline? Copperline is supposed to protect against roots. My experience with drip in turf is it works in small areas we put it in the medium between the road and the side walk in new subdivisions. The areas are normally around 35ft by 4 ft. It does a fantastic job there. Course there are no gophers either lol. What area are you in? And yes there aren't that many good options when it comes to trenching for dripline.. I've even seen a chainsaw looking trencher.

My guess is we’re talking about lateral flow. Water delivery devices (rotors, sprays, etc.) are installed on the lateral which is the pipe after the valve. For example: If a lateral pipe has four heads and each head is spraying three gallons per minute, the total flow through that lateral is twelve gallons. If I “count flow rate from the end of the line backwards” the flow rate would drop three gallons per head. End of the line is twelve gallons (all four heads), three heads going backwards would be nine gallons and so on.
how to calculate totally pressure? if each of rotor need 30-60psi. please help to explain more calculate totally flow rate, size of pipe, total pressure of hold system
Hello! The first step is to know the PSI at the beginning/point of connection pressure/flow. Then need to deduct for all devices (backflow, valves, pipe type & size and pipe runs(how long).
😂😂😂 K-rain... that ish no pro will touch!!! It's not about fancy videos amigos... It's about the products! I would say more, but I don't think you are very constructive with constructive criticism! I wouldn't be surprised if you just deleted this comment and you probably will! The only thing you're good at is copying Hunter's design for PGP sprinklers, exactly! Otherwise bye Felicia!!! no real irrigator would disagree with me who actually has pride in their experience!!!
So y'all know how it works, but you still put out products that don't work very well! Tell me I'm a liar! I've got such a bone to pick with you!!! It's like you just accepted the L in the industry!
@@Krain rotors... how is a technician supposed to move through a property when the sprinkler will get nowhere close to where you move it when checking the left and right adjustments? It always arcs way past wear it looks like it's going to stop when manually moving it... but I have to sit there for 15 minutes for each head because they move so slowly... if I try to get it close and it automatically wants to go back the other way... don't even get me started on the timers!!! I'm talking about the heads that include the key straped to them... it's like you have no interest in the world of technicians. Your timers last forever which is great but your homeowners don't know how to use them!!!! Flip 17 switches For simple, testing programming, etc... and it's almost like you just trying to torture us because they're gonna have to call us if anything goes wrong... your products are clunky and sad... and they will last to stick around and torture you... just remember other companies make products that last too!
@@Krain if you made K-flex good job. That's a good product, but I have a feeling you're gonna bust my bubble on that one... I gave somebody grief when they told me they used that stuff because it was called K flex They assured me it had nothing to do with you...
Toro actually makes products that I don't love but I would recommend them to somebody on a hard budget if that product was what they picked up... that is saying a lot... Toro needs to stick to tractors... This is not a loyalty thing. I do not believe in brand loyalty I believe in capitalism... what I'm wondering is what's going on with you guys?!? do you not want to participate or are you just comfortable making what you're making? Or is a sister Company making enough to where It just doesn't matter? in that case it's not capitalism... it's corporatism and are just looking out for stockholders over everything else. No company I want to deal with, even if the better product is doing the same thing... sad really.

Well done. In my opinion depth of burial of mainline should be 15" to 18" and that of lateral pipe be 12"
Mir Sarfaraz Ali Khan too deep
Pipe should be 6”
Below ground at least here in south Texas
Depends on the pipe size.
Thanks for the feedback
Do a video on site landscape layout near 2acre and tell them the pump discharge also
I will ask, appreciate the feedback.

Not sure where you get 30gpm on the chart when it show, on the left side of the chart 20gpm?
We will take a look and revise.
Man you have to let me know what the music in this video is called, it has absolutely no business going so hard
I'll let the team know. thanks.

What do you mean count flow rate from the end of the line backwards?
