Sprinkler System

We have just finished installing the sprinkler system for the yard. We used poly pipe this time as opposed to PVC pipe that is used in southern California. Pros and cons to each way. Poly pipe can be "pulled" under ground without trenching so that is great. PVC is trenched and you can test the lines and see if there is a leak or if it is broken before you cover the line up. Poly pipe does not have that feature so you have to guess where the pipe could have gotten pinched or possibly even broken. Installing heads on the poly lines are very easy and fast...no glue or mess like PVC. I did some research as to why everyone in Idaho has poly pipe yet everyone in California has PVC. It turns out that PVC becomes VERY brittle in cold weather and breaks easily. It doesn't just break part of it but will shatter the entire line, fitting and all. Poly is a flexible line that is resistent to cold and will not shatter if water freezes in it. It will split part of the line but nothing drastic that cannot be repaired. Also PVC holds pressure better that poly so alot of places have pressure reducing valves on the sprinkler lines seperate from the house. Anyway it runs great and is fully automated. We look forward to having a green lawn in places that don't have the green grass yet. Pictures are comng soon.
