How much does the maintenance of sprinklers equate to?
Nothing really. LEPA socks wear out in 3-4 yrs and growers have been replacing them with LEPA bubbler attachments. Switching between sprinkler and LEPA is a twice a season job, if you continue to do it. Changing nozzle sizes using a dual nozzle kit is a twice a season job. If you hit one driving past the end of a machine you might replace one or two in 10 years.
