SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

My main water line into the house uses 3/4" cupple pipe. For this I plan to use 3/4" PVC for the main supply line of each zone. A few questions:

[1] I plan to order from you the Rain Bird sprinkler heads. Do these heads use 1/2" or 3/4" input connectors?

[2] What size of the PVC shall I use for the lateral lines that delivar water from the main supply line to the sprinkler heads? If the sprinkler head uses 1/2" connector (is it correct?), shall I use 1/2" for all lateral lines?

[3] Do you have Rain Bird sprinkler heads that produce a rectangular spray pattern? Where shall I look for these heads? What are the dimension size of these heads, assuming my water pressure is 55 psi?

[4] I also look for air compressor for wintering. According to your guidelines, it shall provide 10 to 25 CFM with pressure less than 50 psi. I look through the local department store, such as LOWES, MENARDS, they only carry ones with 4-7 CFM. Where shall I look for this?
