Water Pressure Regulator - Good idea to reduce by 50 psi?

It might LOOK like PVC but it is PE (or possibly ABS or HDPE) - often over (and under) aluminum. Rapidaire Fastpipe rigid as well as MaxLine flexible are both aluminum core HDPE and DuraTec is PE-RT over aluminum. RapidAir also makes a blue Nylon flex air line. AIr Brake line is also made of Nylon or PE.

Since the frost line is basically zero, sprinkler lines are usually right under the sod and subject to damage. These days a reputable sprinkler company might be using Sch 40. That might also be to make them harder for the homeowner to fix tho so they get more back end business. I do know the folks with sprinkler systems are always screwing with them tho and that included the commercial operations my wife managed. They had a guy and his helper who did nothing but maintain irrigation on the golf course and he was a busy guy, She had another guy who just did irrigation in the common areas but he usually did have enough spare time to keep 40 toilets flushing.

A cabinet shop I worked at had the main air supply plumbed with sched

We installed underground pvc sprinkers and they lasted about 5 years before they had weather related breaks. Eventually, I abandoned the underground pipes and began using just plain above ground 1/2" mainline tubing w/1/4" sprinkler tubing. It's easier to fix when a branch or winter storm snaps a sprinkler head. This past year I didn't have to replace anything due to winter weather. I did add more sprinkler heads, though, because I made more spaces for flowers.

Same here, they get winterized, run about 8" deep or so. Basically the pipe is low enough to accommodate the head and a right angle fitting.

These days a reputable

One huge advantage with poly pipe for irrigation is that it can be pulled with a machine that just leaves a small slit, no digging of a trench for a pipe. They can pull 100 ft of it in a few minutes. That's a big labor savings, far less of a mess too.

Shows that you can even screw that up. I had a 7 zone system installed

PVC wears out, and it was installed just fine. We did the work on the original, but I've done all the remaining work on the above group drip irrigation system. It's highly adaptable, isn't expensive, and it can be changed around very quickly when needed. I don't have to pay anyone to work on it, ever.

All the lines are open and blown out every fall. Breakage happens when storms cause branches to fall onto sprinkler heads, heavy snow can do the same thing. It's always a cheap fix in the spring and I don't have to hire anyone to fix it, either. It's quite economical and easy to design any number of sprinklers for whatever purpose I need.

Ours are usually lawn mower damage. If those boys on the ZTR do a spin right over a sprinkler head they break it and may damage the pipe below. Just running over them with a truck can screw them up too. That is usually the run close to the road and the homeowner can't even complain because it isn't his property.
