View Full Version : expanding existing system

I have a regular landscape maint customer that wants me to increase the square footage her system currently irrigates.


After some initial research, it dosent seem to be overwhelming.
However, I'm only in the begining stages of my "Feasibility Study", and thought I'd run it by the pros...

It's a skinny rectangle 80' x 8' and I'm hoping that I can just extend the closest existing zone to cover this area.
(How can I know for sure?)

BTW, the skinny rectangle is across a 25' wide paved street.
I will have to go under.
(Hammer drill? Water jet? Any suggestions?)


I greatly appreciate any and all help.

Let me know if I need to give more info....

Need more info,

How many heads are running on the "closest" zone?
what are they, what type and what arc?
What is your water source size?
How much bigger are you making it?
How big is timer and how far from control valves if you have to add one?
The more info the better.

Directional boring is the way to get under the hardscape. Depends on your area and soil type though?

Thanks for the help, Tony!

I'll be at the property early next week and will take a list of your questions with me!

If there is any thing more I can find out for you, just let me know.

~Thanks again!

This is no job for a neophyte.

WHY?

What's so overwhelming?

I need to know, so I can understand...

If you have a sprinkler pro you can trust....otherwise I think I can help you here. I will need more info before I can make the above predictions of you being a neophyte. Do those two know you?

Get me that info, in fact you might email me to tell me you posted it because I get busy and forget to come here during the week sometimes, I am usually out repairing LCO's sprinkler fixes!!lol

Here you go Tony...

How many heads are running on the "closest" zone? Six
what are they, what type and what arc?
Rain Bird Roters
3500 Series
3 are 90 degree arcs
1 is 180
1 is 135
1 is 360
Here is a link to the manual (You'll need "Acrobat"):
http://www.rainbird.com/rbturf/products/rotors/download/3500_Manual.pdf
What is your water source size?
I'll be working off from 1" PVC
How much bigger are you making it?
640 sq ft (80' x 8' rectangle). Existing zone is less than 700 sq ft from my drawing (explained later)
How big is timer and how far from control valves if you have to add one?
Timer is Rain Bird ESP-6
Here's the link to it's manual:
http://www.rainbird.com/rbturf/products/controlr/espmanual/ESP.pdf
Control valves are approx 95 ft away. I'm estimating this distance from an old measured drawing I made and am only fairly confident about it. However, I can take my measuring wheel back out there, if need be.
Directional boring is the way to get under the hardscape. Depends on your area and soil type though?
We are on sand, sand, and more sand.

Thanks for all your help!

A couple of points:

You would irrigate the 8x80 area with sprays but you mentioned the closest zone is rotors...you don't want to mix the two on the same zone, much different run times.

You need to find a zone that is already using sprays and has sufficient capacity left to handle the 8x80 area. (which sounds like close to one zone by itself to be honest). You need to find the water supply capacity in gallons/minute, design the 8x80 area and compute its required GPM and then either add a new zone or find another spray zone that has sufficient 'leftover' GPM to cover the new heads.

Not rocket science, but not 'just add heads' either.

Smithsonmi,
Thank you for the info...and the homework!

Ugh... I was in denial. I'll be needing a new zone.

I'll post that info ASAP.

Thanks again!

Y'all will be happy to know I hooked up with irrig pro with 30 years as a licensed contactor in NC.

He's going to audit ALL my properties and provice consultation (ect) through my learning curve (Another 30 yrs?)

Any advice on how I should structure this business relationship will be very helpful

Thanks

I'll do it for 100 per property plus airfare!!!!

My guess is that you will want him to bill your customers directly as they will ultimately decide if they want the 'audit' or not. Don't get involved until you have their okay. That will cause big problems.

The audits will be free.
He will find what needs to be done.
Then, I will propose the work to my clients.

One thing at a time though...I'm waiting to see how this relationship develops over this particular job.

I will keep posting as to how this goes so y'all can advise me of any red flags.

Thanks alot!

Firstred flag..............free audits
Means he isn't busy.....bad sign
Means he's new........not always bad but watch out
Means he doesn't really mean free

I could be wrong but....

I am swamped, even when not, no free audits

just my .o2[

He's new...in town.
His main bus./life is in NC.
He recently obtained a second home on the island.
Means he doesn't really mean free

On this job, I am treating him like a sub-contractor. I'll do the prep work before and the sodding after, but he is doing the irrigation. During which, he will show me "all I need to know to get me started installing and servicing irrigation systems"...

Sounds too good to be true...:rolleyes:

Now that you have me thinking about it, there are other red flags too....

I may have to start a new thread..."How to shake a sprinkler scrub"


BTW, I'm re-thinking your offerI'll do it for 100 per property plus airfare!!!!
I hear it's CHEAP flying these days...............

Sorry, no way will one job show you 'ALL YOU NEED TO KNOW' about irrigation.

A lot of people think so, that is why I am so busy repairing that crap.

Offer still stands.
