Lateral lines are the pipes or tubing that carry water from your valves to your emission devices, typically sprinklers in a setup like this. The other side of the valve (outlet) connects to your lateral lines. The inlet will be under constant pressure and allows water to pass through only when opened by the controller. One side of the valve connects to the manifold this is known as the inlet. The controller sends a signal to the solenoid which then opens or closes the valve. The solenoid is the part of the valve assembly that is wired directly to the controller. Solenoid valves consist of the valve itself, that is the part that opens and closes to allow or restrict water flow to the system beyond it, and the solenoid. In this article we will focus on solenoid valves, the kind usually found in automatic irrigation and sprinkler systems. There are many types of irrigation valves. You can see a list of available Manifold Kits here: Manifold Assembly Kits.Īvailable manifold parts can be found here: Manifold Parts. Thanks to products like PVC-Lock it is now easier than ever for the homeowner to assemble their own manifold system. We offer Manifold Kits for up to six zones. The one pictured above is for a two-zone system, but options exist for much larger setups. Manifolds come in many different sizes depending on how many valves and zones are needed. The manifold is typically fed by pipe or tubing that is tapped directly into the house’s water supply, but it is also possible to supply it by a faucet or hose connection. As the definition suggests, an irrigation manifold is a pipe that branches into several openings, in this case to deliver water to multiple irrigation valves. Manifold: noun: a pipe or chamber branching into several openings. You can see a list of available controllers here: Irrigation Controllers. Some must be hardwired directly into the electricity, some come with an external transformer that can be plugged into a wall outlet and some are battery operated. They are typically mounted on a wall inside or outside. Controllers do not attach to a hose or faucet. This means if you have a DC controller you will need DC valves. AC controllers are not compatible with DC valves and vice versa. Controllers are connected to the valves by running wire from the controller to the valve itself.Ĭontrollers can be either AC or DC. The controller is similar to a timer in that it opens valves at specific programmed times and durations, however unlike common hose end timers the controller does not have its own valve. The ideas presented here are meant to introduce the basic concepts to the avid DIY’er and create a foundation from which to build.Ī manifold and valve system starts with a controller. The following article is meant as an introduction to these concepts and is by no means a comprehensive training guide that includes everything one needs to know in order to setup an automatic valve system. That’s where manifolds and valves come in. Zoning a system is most often done for several reasons, among them: the flow rate of the water supply cannot keep up with the demand of the emitters, different plants and landscaping have differing hydration needs, the property is large and needs to be divided, or a combination of all of the above. Once your project has grown to a certain size you will find the need to zone your system. Once you have delved into the world of irrigation it will not be long before you begin to expand your system to include other aspects of irrigation.
