Just having some fun.

Everyone forgets that after he hands them 1 dollar each...they now have spent only 27 dollars....not 30. The bellhop doesn't tell them about the other 2...which he keeps. It would have been divided into 3 parts of .66 each...which would make the total they spent.....8.33....or 1/3 of 25 dollars.

The 30 dollars being 27 is the kicker. That's one of my favorites. See ya'

Class 200 pvc is great for most jobs because it is pressure rated high enough and has less friction loss over distance for the same size pipe as sch 40. Its common to use in irrigation.
Except for 1/2" which suppliers around here don't carry because it is just TOO thin. Heck... they may not even make it any longer since I see that it is missing from my Friction Loss charts. We use CL 315 in that size. :D
 
We use Schedule 40 pipe for all 1" applications through 4" applications. There is no doubt that it is a stronger pipe. We calculate into the equation the <very> small amount of friction loss. I would rather lose a small amount of pressure and make my zones just a small amount smaller, or use bigger pipe to make up for the difference. I get so sick of thin-wall pipe that everybody else uses. It is cheap, and that is the only reason people use it. Then they try to justify it any way possible. So what if SDR has a thicker wall at 5" than sch 40! Who the hell uses 5" irrigation lines unless you are on a golf course? Then, you are not using SDR or Sch 40, anyway. Thin-wall becomes so brittle, and if anyone dares to have trucks or equipment on the lawn for whatever reason (tree removal, etc...) you can bet the thin-wall will break. Sch 40 will not. We tell customers all the time that you can run over our heads, pipe, fittings, and all, and should have no damage to the system. Yes, it costs more, but our customers know what they are getting versus what they would have gotten with someone else, and are willing to pay extra for it. We also use Hunter Jar-Top valves for all 1" applications because they are so easy to repair, and generally do not require any servicing to begin with. Raise the bar. Be proud of what you do, and use products that will be there years down the road.

We've never used anything but sch 40...strong, cuts clean, no cleaning flters
& heads of pvc flakes....yes, friction loss has to be considered, but I'd rather
repair breaks in my sch 40 (which happens) than that crap eggshell pipe.
 
I guess I better go pull those 25-30 yr old SDR-21 lines out of the ground and put in Sch 40. Now if I can just remember where all those systems are.

If you want to use Sch 40 because you believe it gives you better performance then by all means go for it. If you want to use SDR-21 because you believe it gives better performance then do it. But it's all irrigation.

Any system that is put in properly at a proper depth and backfilled properly, with the heads and valves done correctly will last for years and years. Many years past the reasonable warranty period. I don't really care what type of pipe is used, what type of heads are used, what valves are selected. Because when you service a system it is T&M. And like it or not, there are going to be things that break in an irrigation system.

What pizzez me off more than the materials used is the creative piping techniques and poor installations. The materials can be easily fixed or replaced. The getting to them sometimes is the biggest pain.
 
CL200 works just fine. The problem I don't like is when I accidentally run my shovel again one of those 1" CL200 pipes and get a gyser of water in my face. That happened to me at my home system once when I was working on it.
I prefer to use Sch 40 because its more durable again equipment breakage and I'm more comfortable using it in rock littered soil.
In our residential systems, the pressure loss in 1" Sch 40 is virtually never a restricting factor, its more likely the 3/4" tube size water pipe.

These are the kind of people I look to hire. The kid I'm training to be an irrigator now is into A-Team reruns. If you had told me all the things I'd be doing at this stage of my life listening to A-Team stories would not be one of them. We are pretty much all class 200 here. When I buy sch 40 it usually has a coat of dust covering sunburn.
