This pressure regulator is deigned for an irrigation system and will regulate the pressure at 40 psi, which is a good pressure to be at for a drip zone. Drip line is rated to operate at a lower psi. If your pressure is too high, it will blow the fittings apart creating leaks in the drip line. This being the case, it is always a good idea to regulate the pressure on the drip zones on your sprinkler system.

Great Knowledge! I’m one season into my tech career and your videos have been very helpful. Thanks so much!
You bet. I'm glad that this is helping. Thant is why I am doing this.
Just what I needed to know! installing new drip zones - off to dig in the dirt.
Good luck. Glad this helped.
Great content! I have a full 3/4" system for lawn and drip. Do you recommend a pressure regulator for the lawn zones? If so, what pressure would you recommend? Thanks!
Great video! Thanks
Thanks for the great info! You mentioned it's possible to do pressure regulation from the "stub" / PVC fitting. Do you have a recommendation on which should be used? Thank you!
You could use one like this and it would work but it is a little big for that location. I have use a smaller one by Senninger Irrigation Inc. They make them in 3/4 and 1". They are a little more compact and work well on the stub up. I tried to put a picture of one in this comment but it would not let me. Sorry.
I am a little confused about whether I need a pressure regulator for my sprinkler to drip irrigation conversion. I am using the Irritrol 2700DPR valve, which has a screw which allows one to control the water pressure in the system. Is adjusting the valve, to lower the water pressure, suffice to stabilize the new drip system on should I still install a pressure regulator at the end of the riser? I can not find any documentation that address that question. Or should it be assumed that a pressure regulator should ALWAYS be installed when using a drip system? Thanks for your assistance.
Pressure regulator before or after an anti siphon valve?
Great video, I am a Novice when it comes to sprinklers , I was wondering if it is normal for pressure regulator to drip ever so often, or did I , not going to lie I did use a wrench, over tighten and likely cracked a little bit 😬
Oh no. It is not normal for anything to be dripping or leaking. It could be that you did over tighten and crack it, but if that was the case it would be leaking more that a drip. It would be spraying everywhere and you would know for sure if you cracked it, in most cases. It may be that you didn't use enough teflon or pipe dope on it and it is just not sealing off. Sometimes a drip can stop over time, but most of the time if I install something and it is dripping or leaking, I just shut the water off and take it all out and do it again. It is a pain, but you want it to be right. In my case someone is paying me to do it, so I have to make sure it is good and right.
great info
Glad you think so!
do these block? If so, is there an easy way to clean them?
Enjoyed your video - is there a reason you can't put the pressure regulator before the manifold if the pressure is too high and you want to reduce it for all lines?
You can certainly do that and sometimes it is a good idea to put a pressure regulator on the main line around the backflow device and regulate the entire system. We had a job where I had to do that. So it really depends on the system and they area and the pressure situation on site. A lot of times you want to keep a good amount of pressure in the system for the spray or rotors zones and just regulate the drip zones. That is why I do it this way.
@@AmericanIrrigator I am also thinking I need a pressure regulator upstream from the manifold for my back yard at the end of the old steel pipe, because I have had the PVC parts there break three times in the past year or two. Twice it was the same part, this last time another, the line mender part I had put in on the first repair. So I suspect I'm getting a big pressure surge. Does this sound right?
Great info. Question - trying to help a neighbor. His poly tube sprung a leak, tube spilt. I put a coupler. It caused another and another and 6 couplers later I thought maybe it's a pressure thing? He did mention he had 4 sprinklers but removed them when he got artificial grass. Now it's simply a giant drip system from the vales out the various trees and shrubs. Any ideas would be appreciated.
Oh man. Well, if the fitting are blowing out or the drip is blowing apart, then it sounds like a pressure issue. If the tubing is just simply cut, like from maintenance workers or animals, then it is just a matter of repairing it like you did. You may have to replace a longer section of the tubing. You know, sometimes when guys install the drip in the beginning, if they are not careful when they cut the wrapping off or the ties that hold it together, they will cut the drip and there will be cuts through out the entire roll. I have had employees do that and when I turned it on, there where leaks everywhere. We took it all out and started over. Hopefully you don't have to do that. Hope this helps.
Are there pressure relief devices that install on the supply side of the valve? We are having issues blowing holes in 2" pvc before the valves on a large community system.
Yes. There are brass ones that are made for that and you can adjust the pressure to where you need it.
Do you have a recommendation for a regulator 'limit' valve. I need to drop the pressure before the valve. Our city water pressure is 100 psi. In no time the control valves leak everywhere and no amount of tightening the screws helps.
We design most systems for 65 psi. You need a minimum of 30 to 40 psi at the head for them to operate properly. If you can regulate down form 100 to 65 ,70, that would help.
@@AmericanIrrigator Agree on what you say. The problem is finding a 'limit' regulator that can be used in a static pressure environment.
My sprinkler heads keep blowing their heads off, way too much pressure. I have access to the supply for the zones its above ground with a ball valve and plenty of room to add a pressure relief, I think the pipe is 1 inch pvc. What would be a good PSI for a sprinkler system to run on? Also do you have links to PRVs?
45 psi at the head is a good pressure to run at. A lot of systems are designed with a design pressure of 65 psi. By the time you flow water through the various parts and equipment you may be at 40 to 45 at the head. If you are going to put a pressure regulator at the beginning of the system, it is a good idea to use an adjustable one, that way you can dial it in to exactly what you need. If you put a 45 psi regulator at the beginning of the system, the last head may not pop up and work properly. Test the pressure first and see where you are at and go from there. I do not have any good links at this time. sorry.
Do my sprinklers need a pre filter? I got filters for my drip but not on sprinklers
What’s the ideal psi for sprinkler?
Ideal psi for drip? I think my emitters are rated for 30psi and my regulator is 30psi
Most of the time you will not need any other filter unless you are on a well. I do use extra filters and sand separators on wells, this helps keep the heads and valves from getting clogged up. Most sprinklers require around 30 to 40 psi at the head to operate correctly. If you have that you are good. Drip needs to be regulated at 40 psi max. 30 psi is good. Drip will operate at even lower psi.
my regulator started making a high pitch noise whenever the water is on. What is happening and do I need to get a new regulator? Thank you.
I'm not exactly sure why it is making that noise. It could be a number of things like it is going out or it has something clogged in it or it is messed up in some sort of way. If it is still working, as far as still regulating pressure and doesn't seem to be affecting the way the zone runs, I would leave it in. BUT, if it is really affecting the zone and seems to be causing problems, then replacing it might be the way to go. Hope this helps.
Why not put the pressure regulator on the supply side before the anti-siphon valves? That way you only have to use one instead of several. Just asking.
You can certainly do that and in some cases it is a good idea if you are in a high pressure area. But if if the pressure is marginal, a little too high for drip but good for the rest of the system, like for spray zones or rotor zones, you would want to just use a pressure regulator on the drip zone like we were doing here. Every system and area is different so you would want to test the pressure and design and install the system accordingly.
Why not put it on the inlet side of the valve? To reduce wear on valve
If you had extremely high pressure this would be a good idea, but in most cases the valve can handle normal amounts of pressure. So there would be no need to regulate the pressure for the valve itself. And these valves do need some pressure to operate properly, as far as opening and closing. But you do need to watch the pressure for the drip tubing. 40 psi is recommended.
Do you need a pressure regulator on zones that are using bubblers to water trees?
Good question. I typically do not use pressure regulators on bubbler zones, just zones with drip tubing. Bubblers tend to be ok.
@@AmericanIrrigator Thanks so much! I’ve been enjoying all your videos.
Pressure regulated check valve?
No , this is just an in line pressure regulator. I could see how it would look like a check valve too.
I had a guy install pvc pipes and sprinkler heads but the heads are not picking up need help
First question is, was he licensed? It could be a lot of different things. Possibly a broken line. Too many heads per zones or wrong nozzles, trying to spray too much water at one time, going over the gallons per minute. Piped wrong. A clogged up line somewhere. Low pressure, not enough pressure to pop up the heads. Just to name a few. You might want to call him back out to go over it and fix it. Sorry not much help.
