Installed my RPZs and have a question regarding pressure

Quoted from "Wet_Boots" I thought I already answered this. You're doing a good thing with using sch 40 PVC between the RPZ and the manifold. None of the pressures you have listed present a threat to the sprinkler system. Master valves (two of them) should work with your Rachio controller, which lists an output current capability of 1.3 amps. Nearly any common electric valve you could choose nowadays will have a solenoid with an inrush current of 0.4 amps or less, so two master valves and one zo...

Installed my RPZs and have a question regarding pressure

I have decided to not take any chances and install pvc sch 40 from rpz to a new master valve. I think its good insurance. Its only about 1' of lateral pvc connection from rpz.

Installed my RPZs and have a question regarding pressure

I live in a cold climate where freeze is a concern. In addition, my property has several dozen obstacles that I had to dig under during trenching (tree roots that are as wide as my shoulder, several metal old drain pipes, sewer, old walkaways that is concrete, etc), so as a result my entire system is 100 psi 1" poly with pinch clamps and blue inserts for connections. My manifolds are the same. Up until yesterday, I had this system connected to a hose bib and I would turn it on/off daily when I n...

Hunter Brass Balve as Main shutoff in Basement

Quoted from "Wet_Boots" If a brass plumbing item is lead-free they will specifically tell you that in its description. I can read the Hunter product description of your valve and know that there is no claim of it being lead free, and I also note that there is no claim of it being suitable for contact with the potable water inside your house. Based on the clearly understood standards of professional sprinkler work, there would never be any such contact, and subsequently, no need to get into the ...

Hunter Brass Balve as Main shutoff in Basement

Quoted from "Wet_Boots" Pipe is plenty strong. Unless you are a horribly incompetent plumber, you don't worry about the supply plumbing of a sprinkler system you install yourself. Much more to the point, is why all this indoor plumbing? Professionals minimize indoor plumbing. Bring the water outside and switch the plumbing material to plastic. "Lack of willingness to trench" is why you hire this kind of work to be done. For the money, you get over your lack of willingness, and trench where and ...

Hunter Brass Balve as Main shutoff in Basement

Quoted from "Wet_Boots" You will not be able to install a basement master valve and have a good system when there are backflow preventers downstream of said master valve. If you have to have a master valve on a system with two supply outlets, then bite the bullet and install two master valves, one at each location, downstream of the backflow preventers, which is the only location where they belong. Why wont it be a good system? The primary reason for this isnt actually my lack of willingness to...

Hunter Brass Balve as Main shutoff in Basement

I want to put a master shut off valve in my basement which i can remotely control which only turns on when sprinklers are running. This has to be in the basement because there is a front and back lawn and both have seperate lines feeding from basement. In my basement there is going to be a tee after water meter, then a manual shut off ball valve and after that I want to put this valve. Then each side of the house has their own reduced pressure backflow preventer outside. I already bought this va...

How long can a drip zone be?

I want to use a drip line for my shrubs and was wondering whats the limit as far as how long it can go? Does the same psi/gpm rules that we have in regular sprinkler heads apply here? I am planning on using a kit that screws onto a regular 1" or 3/4" line as a regulator to reduce the psi to 30. I dont know whether I should break it down into multiple zones or if I can have 1 sone just for drip line for ky entire property.

PVC vs Poly (Under concrete walkaway/frost)

As I continue building my irrigation system (I now have 5 zones covering 15,000 sq ft), I have a situation where in my front lawn, I have to dig a tunnel underneath our front walkaway path that leads to our main front door. It's a 3 feet wide path, about 3 inches of concrete on top of it is a 1 inch tick masonry stone (just for visual looks). Below the 3 inch concrete, is about a foot of rocks as well as filler marble (medium size). I actually digged this tunnel today (did take me 3 hours). Why ...

Tree trunks

Quoted from "Wet_Boots" Tree trunks don't die from lawn sprinkler watering. If you directed high pressure fire hose water at a tree trunk, you could do it some damage, but a sprinkler head spraying 3-4 gpm with 50 psi at the head is no big deal. thanks, I m at 2.5 gpm. So a professional wouldnt mind having sprinklershit the trunks once in a while?

Tree trunks

I live in a heavily wooded township where average property age is around 60-70 years and as such there are a lot of very tall (60-100 ft) trees in everyone's property. I have a 0.5 acre yard I am working on building a sprinkler system on and I have total of 37 trees excluding small ones. 25 of these trees have massive tree trunks (well over 3-4ft in diameter). I read all about not watering the trunks and keeping them dry but the more install zones/heads, the more I realize the trees are creating...

Hunter not getting the advertised range

Quoted from "Wet_Boots" Assume nothing so high as 10 gpm at operating pressure. Measure it, just like a pro who wants to employ a hose bib would measure it. The key to getting accurate numbers is to have a valve downstream of your pressure gauge. Close down that added valve, until the gauge is showing the pressure you want. Thanks, I have done that and I am getting 70 psi and exactly 11 GPM. I am going to assume 50 psi and 10 GPM from now on as conservative figures. Are these good numbers? Also...

Hunter not getting the advertised range

Quoted from "Wet_Boots" Do the proper plumbing and forget all about running a system from the hose bib. I'm not saying it can't be done, but a pro only goes that route if it saves a lot of money, or gets around an impossible plumbing job, like in a completely finished basement. A proper "bucket test" does not result in a flow number alone. It results in a combination of simultaneous flow and pressure. That combination is what you get to work with, and it will never be as high as 16 gpm, unless ...

Hunter not getting the advertised range

Quoted from "BackflowInspector" I think you have given enough information to make an educated guess to the situation. You are probably good for 5 to 8 GPM Flow Rate to get you the pressure and volume you need to run the Hunter at advertised flow and distance. You got 5 to 8 gallons and coming off of the hose bib you should probably stay closer to 5 GPM. So If you use an 8 GPM nozzle that is about 8 GPM you are done. Or You could use two heads each with a 4 gallon nozzle that would equal 8 GPM. ...

Hunter not getting the advertised range

I am putting together my own underground sprinkler system. I have a corner property whereby 85% of my property is surrounded by roads. As a result, I have a fairly big lawn. To top this off, I have 37 trees in my property of which 25 or so of them are massive trees that are over 60-80 ft tall. In addition, I am on a fairly steep hill and my soil is very rocky/clay. It seems like the township as well as the utility companies have lost the plans and are not able to mark the underlying utility line...
