Shrub Sticks & Nipples

In most cases, shrub sticks are secured in place through their connection to the irrigation system. However, if the soil is loose or if the shrub stick is tall, it may be a good idea to secure it with a stake or anchor. This will help prevent it from tipping over or becoming dislodged in the wind.

Most shrub spray sprinklers perform best at approximately 30 PSI. When pressure is too high, it can cause misting and uneven coverage, while low pressure may reduce the spray radius. Measure pressure while the zone is running and use a pressure-regulated sprinkler body or inline regulator when needed.

Yes, threaded irrigation nipples usually need seal tape or an approved thread sealant to help prevent leaks. Wrap the tape around the male threads, typically two to four turns, while leaving the first thread exposed so tape does not enter the system. Do not use seal tape on barbed, compression, slip, or gasketed connections.

To determine which sprinkler nipple you need for your sprinkler head, start by checking the thread size on both your sprinkler head and the irrigation system. Next, ensure both the sprinkler head and nipple have matching thread types. Finally, choose a nipple length based on how high you want the sprinkler head to sit.
