I am about to install a sprinkler system at my home and would like some advice as to which poly pipe I should purchase. My static pressure fluctuates between 65 and 75 psi. Should I use 100psi rated poly pipe or should I spend the extra money and buy 160 psi poly? I live in upstate New York so freezing is an issue. I understand that I will have to blow out the system for the winter - I am just curious if it is worth the extra money for the thicker walled pipe. Also, where do most of you purchase...
