Welcome to my long-awaited vlog series where I take you along with me on my jobs and learn with me along the way!
In this first episode you’ll observe me resolving coverage issues in a rotor spray system AND inspect and repair the adjoining drip system. You may learn things here that you wouldn’t otherwise learn anywhere else some come along for the ride!

Very helpful Tom
Thank you for taking us along.
You bet
You make the best videos!
Thank you!
I wi!sh you were in central Washington. My sprinkler design of 30 years ago is a mess and I've been struggling with proper coverage every year since. I could use a good consultation! Thanks for the great videos
Randy, are you able to draw your layout on an 8x11 sheet of graph paper and answer some pertinent questions?
After watching another of your fine videos, I decided my backyard lawn needed to Hunter Pro-Spray PRS40 heads instead of just the regular Hunter 4" Pro-Sprays that I had. MP1000s coverage just not working correctly across the lawn. The only problem so far is that the PRS40 heads are 2" longer than the 4" Pro-Sprays. Not a big deal but I am going to have to dig out at least 2" for about 6 head so they are flush with the ground and not stick up 2" high. Thankfully Phoenix is cooling down so I can do this before I seed my Winter perennial rye grass.
Marc, The 4" Pro-Sprays have identical bodies. The only diff is the guts. If you have Pro-Sprays that are shorter then they are 2" or 3" models. The way to tell is to pull up the shaft and measure it. The shaft length is 4" on the 4" model. Let me know what you learn.
@@SprinklerPros OK I am going to send you as concise an email as possible as I have 2 main problems. One I am not getting enough PSI at the heads but my calculations show that I easily should. Second, I was able to install almost all of the PRS 40 heads flush with the lawn except for about 4. Wondering if I can use the shorter 4" body Pro-Sprays that have 1" shaft (2' w/mp1000 rotator attached).
For sprinkler heads, can they be added in series after an existing head (assuming the GPM isn’t too high for the zone) or so they all need to branched off of the main line?
Andrew,
They can be added in series to a point. Each nozzle arc and distance (example: 12Q, 12H, 15F) uses a different amount of water per minute (GPM: gallons per minute) and that must be considered based on the size of pipe being used. 3/4" schedule 40 PVC pipe can only safely handle 8 GPM. This math must begin at the street (or other source of water), then thru the feed pipe from the street to the valves, then thru the valve sizes and piping, then out to the heads. I will be creating a video (series) showing how to do the math. I have a video or two already in my Design series that teaches the basics. Does this help or was that helter skelter?
When you mention "if the GPM isn't to high for the zone" I assume you mean PSI?
@@SprinklerPros thanks for the reply! The zone is currently setup with six rotors and 12 GMP based on the nozzles (I know there is a little variability with nozzles but figure it’s at least close). So if I add two more rotors, i would plan on swapping nozzels in order to maintain 12 GPM for the zone.
The key concern I have based on your response is what diameter pipe is running down the center of the lawn and what diameter is running to each head off of that main/center line. Might need to do a little digging! Thanks for your helpful info!
