View Full Version : How hard are your nipples?

Now that I got you to look, here's my problem. I have client that has 2 irrigated acres. Every week for the last 3 weeks "we" have broke a sprinkler while mowing. Problem is they are breaking at the nipples. Anyways these things arent visible and we are not clipping them. The weight of the mower must be breaking them. The system is over 10 years old and the nipples are rock hard. IMO the system needs to be updated, and although we are usually responsible for accidents these are not preventable and therefor not my fault. Any suggestions?

my buddy installed a system a few years ago with this same problem

Toro risers were to brittle and broke almost yearly...He wrote the company,they gave him 2 bags for free....
I think he is still replacing them...

good luck..

replace all nipples with swing joints?

have you dug up to see if they are actually poly nipples, could it be bad construction and they are using a solid piece as the nipple (ie less give to large mowers).

They are solid. I replaced a few last year. I didnt even know about the last three till this morning. She came out livid cause her irrigation guy has been charging her $100 a pop to throw on a new nipple. Im not an irrigator, but Im more than capable of repairing a system since I worked for an irrigator for 2 years back when. I have to say that almost all my accounts are irrigated and only 1 out of every 10 even has a clue on how to properly use, maintain, or understand their irrigation system.

For a hundred a pop, the replacements should be brass.

I used Toro's 2-inch poly nipples, way back when. Especially popular was the 1/2x3/4 nipple, which makes replacement fun.

Swing joint aint no good down here. Maybe up north with those other yahoos though:usflag:

I just miserably jacked with two 4" popups yesterday on funny pipe/ell that my guys broke the other week. Even the funny pipe was pushed way down in the clay, and got the head all bent up. We need the rigidity of poly nipples here,

I forgot all soil gets softer as you go north. It's like cotton by the time you get to Canada. :)

We have sand, sandstone, clay (probably different for yours though), shale, granite, and many other types of soil. Almost all swing piped in the last 15-20 years. Except for the yahoo contractors that don't know what they are doing. Or Joe Homeowner that just just know there is a difference.

And why is that?

The clay shifts a lot here. Swing joints in high traffic areas but poly nipples in the low traffic area. Nobody here uses sj the raise heads, too much digging. Even with sj we use 1/2 by 3" c/o exts.

Very true. our soils also expand and contract with the freeze/thaw of winter/spring though.

Shifts alot here too, but still use them with nary a problem.

For instance, the site which I'm building my house on right now has a PVR of 6.8, which means my soil has the potential to rise vertically 6.8 inches whenever it feels like it. Theoretically speaking, your 4" popup, could basically become a 2.8 inch riser is the soil feels like it.

Clay here is unreal. It thrashes around house foundations like you wouldn't believe. I ended up making my exterior beam 42" deep. Most houses here are 24" - 30".

Just think of what that soil would do to a sprinkler head.

Kiril

Theoretically speaking, if you maintain a constant SMC your soil will shift very little.

EagleLandscape

I would agree with you on that one.
Can't stop the crazy home owner that makes the call to completely turn off the system for weeks cause it rained. We all know that one is a lost cause.:)

How about using flex pvc. I have found that heads and lateral lines will never break when flex is used because of how much it will give under pressure.

Neither funny pipe or swing. I am speaking of black flexible pvc. You cut it to desired length and then add the appropriate fittings. Its the only thing I use as a riser, especially on rotary heads.

Isn't that what they use for hot tubs? Link, please.

It is very similar. The only real noticeable difference is that in hot tubs they use white and for irrigation use it is black. This stuff is amazing and in my opinion makes all other types of risers obsolete. Especially swing pipe or funny pipe.http://http://www.flexpvc.com/cart/agora.cgi?product=6_Flex_PVC_Pipe_2_inchThe link is for a company online that sells it though I have never used them before. I buy mine from John Deere Landscapes or Ewing. Highly recommended.

pvc threaded tee, on it's side, barbed ell, swing pipe, barb, Marlex ell, sprinkler. Solid swing joint for big rotors...always a Marlex.
That "glueable poly" is trouble if adjustments are needed: you're moving glue joints. :nono:

Use a mans swing joint.

Nipples and 6" valve boxes are the way of TX irrigation. No good reason not to use nipples. Plus when a hot babe walks by its always fun to yell at a coworker "Can you grab me a couple of nipples while your at it."

I'm surprised the mutant oozing clay doesn't just spit the baby valve boxes out of the ground entirely.

We are so good at this we set them low so that the clay will push them to their appropriate spot. Part of TX irrigation is predicting the expansion of the clay and installing accordingly.:rolleyes:
