Rainbird makes the
1800-RETRO kitthat can replace a standard popup spray head and provide filtered pressure-regulated water for your drip application. If turning down the throttle screws on remaining popup sprays doesn't work for you, there are blank caps to be had, and even a
non-brand-specific plug assembly
If the zone you are converting has rotor heads, the unused heads have to be removed and replaced with threaded caps or plugs, which of course is a remedy for popup sprayheads as well.
