The “Ins and Outs” of Drip Irrigation Manifolds

Drip irrigation manifolds, also known as multi-port emitters or low-volume bubblers, have been specifically engineered for landscape irrigation, catering to the connection of ¼” micro-tubing (or dripline) to a ½” male pipe thread riser. These specialized products offer versatility in design and function, finding application in various scenarios, notably in new PVC pipe-based low-volume irrigation systems or the conversion of existing residential sprinkler risers to more efficient drip irrigation systems.

When determining the appropriate model(s) for a specific site, it is crucial to consider several factors to ensure enduring success:

  1. Outlet Selection: Choose the number of outlets based on the quantity and size of plants to be irrigated per manifold. Plan for future expansion by including one or two unused outlets.
  2. Flow Rate Consideration: Select the manifold flow rate according to the water requirements of the plants, the type of emission devices installed (if any), and the soil type at the site.
  3. Durable Design: Opt for a product with a robust and durable design, ensuring UV resistance. It should be pressure compensating and capable of withstanding variations and surges in incoming pressure.
  4. Ease of Maintenance: Preferred models should be easily disassembled for convenient maintenance. Additionally, models equipped with a pre-filter or screen to prevent clogging are recommended.

By taking these factors into account, one can ensure the optimal performance and longevity of drip irrigation manifolds in landscaping applications.
