Orbit 57250 2-Valve Heavy Duty Preassembled Manifold

This pre-assembled manifold is designed to work with a 5-valve system, and any timer that supplies 24 volts DC can be used with it. The water input can be easily switched from left to right without needing any tools. It is necessary to connect a back flow preventer between the manifold and the water source, and to winterize the device and system by blowing it out with air. The valves are one inch, which is suitable for use with one inch black irrigation pipe. Overall, customers have found this pre-assembled manifold to be easy to use and durable. It is a convenient solution for setting up a irrigation system, and is compatible with a variety of timers. The ability to switch the water input from left to right is also appreciated. Some concerns have been raised about the need to purchase a separate back flow preventer, and the fact that the video in the FAQs section was not working.
