Standard Drip Irrigation Kit for Container Gardening

Congratulations on your purchase of a Standard Drip Irrigation Kit for  Container Gardening with ¼” Micro-tubing Mainline from Drip Depot!

Please take a few minutes to read through these instructions and familiarize yourself with all the parts. For assistance with part names and details, you can print the list of parts included in your kit from the Kit item page on our website.

Drip Depot Irrigation kits are modular in design, as no two gardens are completely alike. Should you have any questions while installing your kit please feel free to email our Customer Support team or review some of our many resources in our Education Center, found under the "Learn" tab in the menu bar on our website.

1. First step is to install your Head Assembly. Drip Depot Kits come standard with garden hose thread components for easy connection to your outdoor spigot or garden hose. Hand tighten only, no teflon tape or pipe dope is required with hose threaded connections.

a. Install the Backflow Preventer also known as a Hose Thread Vacuum Breaker, included in your kit, to the outdoor spigot. Ensure this item has the rubber washer seated completely down inside the female threaded connection prior to installation.

b. Next, install the Filter, included in your kit, to the vacuum breaker or backflow prevention device. Please ensure the rubber washer is seated completely down inside the female threaded connection prior to installation.

c. The Pressure Regulator is installed after the filter. Again, ensure the rubber washer is seated completely down inside the female threaded connection prior to installation. Please note the directional flow arrow on most pressure regulators for proper installation.

d. Lastly, the Female Hose Thread Tubing Adapter is installed on the outflow side of the pressure regulator. A helpful tip is to connect your tubing to the tubing adapter prior to connecting to your head assembly components. Most tubing adapters have a female swivel end for ease of installation.

*Please note: If using a hose-end water timer to automate your drip system the Head Assembly must be installed after or downstream of the timer or valve (see illustration below). Drip irrigation products are not rated for constant pressure use. Many municipal codes require the use of anti vandalism protection (set screw) on an outdoor water spigot backflow preventer. The J10 locking screw may qualify when properly installed directly on the outdoor hose bibb. If used on an automatic water timer for your irrigation system we recommend not tightening the screw as the plastic threads can be permanently damaged if backflow device is removed.

2. Determine the best layout for your ¼” mainline to reach all your container plants. Keep in mind the ¼” micro-tubing has a 30’ maximum single run length. Lay out the ¼” micro-tubing.

3. At each container you will cut the mainline and insert a Barbed Tee fitting. Then cut another section of the ¼” micro-tubing to reach from mainline tee fitting into the container. Attach one end of this tubing section to the barbed tee and the other end to the barbed inlet of the dripper.

4. Snap the dripper line into the Stabilizer Stake to secure, then insert the stake into the container.

5. Connect the mainline ¼” tubing to the remaining barb on the barb tee and continue to the next container.

6. Repeat steps 3 - 5 until you reach the last container. With the last container you can just connect the dripper into the end of the ¼” micro-tubing, snap into the drip stake and insert into the container.


  1. Containers over 12” in diameter may require more than one dripper for adequate coverage.
  2. To avoid over-watering or wasting water, containers are often watered for shorter time periods but more frequently than in-ground plants.
  3. Remember the 30/30 Rule for ¼” tubing: maximum 30’ run lengths and 30 GPH (gallons per hour) total flow. See the Tubing Buying Guide for details of tubing capacity.
  4. If you live in an area where the temperatures drop down to below 37 degrees Fahrenheit, you must winterize your system. See our Winterizing Instructions.
