Show effects of too high of psi at pop up heads. I have 130 psi feeding backyard, which is trade off for higher hose throw versus needing lower psi regulator for popup heads. Can pressure regulating heads take care of this high of a difference?? Thanks!!
In a way it could increase pressure because if you get good pressure with 3 and you need it for 6 then your pressure will spread better across the zone if you have prs sprinklers across the whole zone
Good thought. Not sure I quite understand, and either way, I think what you mean is that if the PRS regulates psi the nozzle will be at a lower gpm, and therefore there is less psi loss due to friction. PSI can only be increased by a pump or gravity. -Andy
Going thru the MP rotator spec sheet and noticing that minimum needed is 30psi and recommended is 40psi. If i go with a ProSpray PR40 but adjust the nozzle to the minimum radius, will I experience misting? Should I go with a PR30 instead? I am thinking of 40 so I am covered if I want to adjust to a larger radius but would go with 30 if its more efficient in locations where I want the tighter radius pattern.
w/ no appreciable rain in over 4 weeks, I wish I had 50 PSI @ my tap.. just about get 40 here on top of the hill.. so some states force you 2use PR heads whether it makes sense or not? Are the PR nozzle heads different from the non PR? if I only have 33 PSI in field @ the furthest head , what is the sense of being forced 2use a PR head? THAT, just like government, increases costs w/little discernable improvement.
You nailed it. In some states, you cannot purchase standard spray bodies, only pressure regulated spray bodies, even if your pressure is very low. I agree, it's a bit excessive and benefits manufactures who can now sell more expensive equipment. Alternatively, an inspector could inspect each system to ensure proper regulation, however, that might be more costly in the long run, and nearly impossible to accomplish. So for now, it is what it is, in the attempt to use water wisely.
Thanks for the video! Motivated me to find out the pressure of my own system. I haven't had many issues other than 'weak' PVC joints, but would 130psi at the source be excessive for residential? (I had a spickett installed w/the system ~ 3ft from the main valve) Also, (and this may be fodder for video?) Is it ok/wise/whatev to have MP heads and rotators in the same zone? thx again!
Yup 130psi is very excessive. My recommendation is to install a pressure regulator for your entire system, this is often accomplished by adding the regulator inside your home. You can absolutely have MP Rotators, and standard Rotors, on the same zone. The goal is for the application rate of every sprinkler on the zone to be the same, if possible. MPs & Rotors have approximately the same application rate (typically 0.30 to 0.40 in/hr). Standard pop-up spray nozzles have an application rate of 1 in/hr or more - so it's important not to mix MPs with Spray Nozzles (or rotors & sprays). Good luck! -Andy
This is a great video.
Thank you! Would love to know if you have any recommendations for future videos.
Amazing video thank you, I just subscribed to your channel
Thank you! What should we discuss next?
@@Andy_Humphrey if haven’t already done so maybe a video about the MP rotator, how it works and why it’s better than traditional nozzles

I'd go with the PR40, this is the recommended psi for the MP Rotator (40psi). 30psi is recommended for traditional spray nozzles.

forgot to add, sounds like the pressure is high based your info. //
