Manifolds For Drip Irrigation

In this video, we’re covering the DIG 12-outlet drip manifolds. They’re an awesome way to convert an existing sprinkler riser into a small drip system. Dwayne Smith here, the Sprinkler Warehouse Product Specialist. Let’s get started!

The DIG Top Manifolds Can Turn An Existing Sprinkler Riser Into A Drip System

A drip manifold is a multi-outlet emitter. It splits water from a single source into multiple directions, usually somewhere between 4 and 12 different streams. In the case of the Dig Top Manifolds, there are 12 outlets to channel water from. Tubing directs the water to the plant’s roots.

The DIG Top 12-Outlet Manifold Connects To Emitter Tubing

The manifolds install on a shrub stick or riser.  They can be installed above ground or underground in a valve box. In the case of the DIG TOP manifolds, there are 12 individual outlets to channel water from. the emitter tubing which is sold separately can either be run underground until it reaches the plant or you can run it above ground and cover it with mulch. 

Some Of The DIG Manifolds Already Have Pressure Compensating Emitters

Inside the DIG TOP manifolds, there are these little individual pressure compensating emitters. You can buy the manifolds with these emitters already inside. The Top-030 comes with 3.3 gallons per outlet emitters installed. The Top 020 comes with 2.2 gallons per hour emitters. The Top 010 comes with one gallon per hour emitters. And the Top-005 comes with .6 gallons per hour emitters. There’s also a TOP-triple zero that comes with no emitters in it. For this one, you’ll need to purchase the emitters you want and install them.

The Emitters Are Available In Different Flow Rates For More Precise Watering

The emitters come in sets of 12, and they come in four different flow rates.  Blue – 3.3 gallons per hour. Purple— 3.3 gallons per hour. Green – 2.2 Gallons per hour. Red – 1 gallon per hour. Black – .6 gallons per hour. For any of the Top manifolds, you can change out the emitters to completely customize your manifold.

Let’s change out some emitters. Unscrew the top.  Remove the filter. Then pull out the emitter using a fingernail or a small flat head screwdriver. Replace it with the emitter of your choice. The flat side of the emitter goes down. Just like that.

The Top emitters also come with these caps. Like this. So, you can close off some of the outlets. Just like that. Reinstall the filter. And close up the manifold. The TOP manifolds work with both 1/8-inch tubing and 1/4-inch tubing. To install 1/8-inch tubing, just wiggle it in like this. To use the 1/4-inch tubing you need to purchase these converter barbs. The converter barbs come in different colors which is a handy way to keep track of emitters with different flow rates.  There are also these elbow adapters, which are helpful when your manifold is installed close to the ground.

Quarter-Inch Tubing Can Run From The Emitter To The Root Zone

To do quarter-inch tubing, I find it easier to put the converter barb into the quarter-inch tubing and then install the converter barb into the manifold. From here you’ll run tubing to the plant you want to water.

We also sell a couple of different kits that include a TOP manifold with emitters, 1/8-inch tubing, diffusion plugs, watering stakes, converter barb’s, and eight emitter caps.
