Orbit 54025 Plastic Flush Head Sprinkler with Brass Half Pattern Spray Nozzle

Flush head sprinklers are quite common in systems from 20 or more years ago. These systems are still very serviceable, and the pop-up flush head is an excellent way to keep them in good shape. The version with pop-up action gives an extra inch or so of spray height which makes it more suitable for grass, while a traditional flush head is more common in above-ground applications such as shrubs and flowerbeds.

For replacing existing low-profile "flush" sprinkler heads in landscape areas, precision-machined brass or molded plastic ensure consistent spray quality. These flush heads are available in full, half, and quarter patterns to suit a variety of landscape designs. They are also available in fixed nozzle height for shrubs and 1.5-inch pop-up height for lawn, and are compatible with flush heads from Orbit, Champion, and other major brands.

The brass nozzle includes an adjustment screw which allows you to reduce the spray pattern down to 75 percent of its maximum radius of 15 feet. Flush heads have 1/2" female pipe threads (FPT) and are typically mounted on a 1/2" male pipe thread (MPT) rigid PVC or cut-off riser. The flush head wrench is an accessory which makes it simple to remove and install flush heads without extensive digging. The flush head nozzle is also easy to replace with a brass flush head spray nozzle with male threads.

However, these flush heads do not have pressure-regulating riser stems and are not for sale in California and other states which require pressure regulation. The recommended operating pressure is 30 PSI, and they are for outdoor irrigation use with cold water only.

In summary, these flush head sprinklers provide a cost-effective and efficient solution for maintaining older irrigation systems, offering a range of customization options to suit various landscape designs. The non-pressure regulating nature of these heads may be a consideration for some users, so it's important to check local codes and regulations before installation. With the right accessories and proper installation, these flush heads can help keep your outdoor irrigation system running smoothly and effectively.
