Answers:    rotary heads should be spaced 22 foot apart in all directions using a W similar to pattern ,spray heads should be spaced at 12 foot apart using 15 foot nozzles in a W like cut-out for double coverage ,which is the best (a)min. 6 inch deep in non freezing nouns . also keep in mind that for an average home , for respectively zone ,or station,you must start with a 1 inch pipe ,then stifle the size to three quarter inch pipe ,then reducing to half inch pipe. as a rule for a rotor zone you should remember 3-2-1 ,gist 3 heads on 1 inch pipe then mute ,2 heads on three quarter pipe ,reduce to partly inch pipe ,then 1 head on partially inch. spray heads as a rule is 4-3-2 ,using the same contraction description as above . for free advice farther check out , www.thebowlesters.com.
A minimum of 6" for all PVC piping. Use a flexible pipe on the closing stages known as "funny pipe" to get the herald to the correct level with the prairie.
