Expand An Existing Drip System

Considering that your Raindrip system is built to last, you may find the need to expand your system over time, as either your plants grow or you decide to make changes to the landscape.

To expand your existing Raindrip System, there are two main considerations: the size of the new area you wish to cover, and the nature of the plants you wish to water.

Expanding a traditional Raindrip system:

For a system made up of our standard Raindrip components, you’ll need the following:

  • ¼” tubing to extend off the mainline
  • Emitters for the new section you wish to water

    To determine which watering devices you’ll need and the quantity of each, use our reference guides (below) from the Planning Section of this website. These are divided by plant type. 

      After this, you should have a list of the parts you’ll need for each plant zone.

      To install, simply insert or attach the additional emitters and/or feeder lines.

      • Emitters can be inserted directly by punching a hole in the mainline with the hole punch, then inserting the chosen emitter
      • ¼” feeder lines can be attached to the mainline and “branched” out to surrounding areas. Simply punch a hole in the mainline with a hole punch, insert a connector, tee, cross, or wye, then attach the desired ¼” tubing. Cut the ¼” tubing to the desired length, insert emitters into the open end of the ¼” tubing, and place where needed. Use stakes to hold the tubing and emitters in place.

        Expanding A SimpleDrip System:

        Expanding a SimpleDrip system is straightforward due to its modular approach – in fact, the most common method of expanding your SimpleDrip system is to add additional feeder lines to the mainline.

        To add an additional feeder line, simply identify the plant grouping you wish to water from the below list –

        • Tree
        • Large shrub (over 4 ft)
        • Small shrub (under 4 ft)
        • Flowers and ground cover

          Once you have identified this, you will know which Step 3 SKU you’ll need for expansion. To install the components, follow the SimpleDrip Installation Guide regarding how to install Step 3 of the system.
