Tips & Tricks

Upgrade Your Drip Hole Punch & Save Time

A clean cut makes it easier

Some drip irrigation hole punches are shaped like a pencil and simply poke a hole as they push through the tubing. They require more force and can slip off of the drip tubing before they make the hole. The Super Punch (shown here) has a squeeze handle and is only $9.90. A less expensive option is our Deluxe Hole Punch which has a sharp, circular cutting edge. It's comfotable, easy on your hands, and costs only $3.60.

A Paper Clip Quickly Cleans a Hole Punch

Insert the wire to clear the tool

A good hole punch will actually cut a tiny circle out of the drip tubing. The plug of tubing can be removed from the cutting edge of the punch with a paper clip. Push it through the cutting end to clear any plastic debris.

Fix Little Holes With a Goof Plug

Doubles as a 1/4" end plug

If you make a mistake and poke a hole in the wrong place on a drip line, insert a goof plug (small barb). If the hole gets worn and leaks a little, pull the plug out and use the large barbed end. Goof plus are also used to plug the end of 1/4" micro tubing.

Adjust Water Flow to Garden Boxes With a Flow Control Valve

1/2" Valve fits over mainline tubing

These valves are great when you have garden boxes or drip areas that you may want to turn off seasonally. You can reduce the flow or shut it off completely. 1/2" Flow  Control Valves are installed just like a compression coupler.

Sloping Property? Use Pressure-Compensating Emitters

Drip emitters with consistent output

When installing a drip system on a slope, non-pressure-compensating emitters will deliver less water at the top of the slope and more at the bottom. Install pressure-compensating emitters to ensure even flow rate even if the elevation changes. Non-PC emitters are best on flat lanscapes.

FAQ

I want to install my own drip irrigation system. Where do I start?

The best place to start is our Drip Irrigation Basics & Installation Tutorial. You'll learn how to plan & design a drip system, connect to a hose bibb, and how to compare drip emitters.

How do I determine my household water pressure?

Please read our tutorial on Determining Your Household Water Pressure.

How do I determine my water flow rate?

The flow rate is the amount of water flowing through your water supply line. Since drip emitters and micro sprays consume x gallons per hour, it is important to know the flow rate available to feed your emitters. It is measured in gallons per hour (GPH). To determine the flow rate out of your faucet (hose bibb, spigot, hydrant), read our tutorial on Determing Your Flow Rate.

How do I choose the right drip emitter (dripper)?

Drip Irrigation design is flexible. There is no perfect solution. However, there are a few guidelines to consider when choosing & comparing drip emitters. The first consideration is pressure compensating vs. non pressure compensating emitters. Pressure compensating emitters contain a silicone diaphragm that is designed to keep the flow rate consistent.

A pressure compensating emitter will deliver the stated flow rate (e.g. 2 gallons per hour) within a pressure range. The output of non pressure-compensating emitters will vary as the water pressure varies. If you plan to install the maximum number of emitters a mainline, you should consider pressure compensating emitters so that you don’t run out of water flow. Non pressure compensating emitters are designed to operate at 20 psi or less, so they should be installed with a 20 psi drip regulator.   

Pressure Compensating Emitters

• Deliver the stated gph (gallon per hour) even if pressures range from 10-50 psi
• Works well with elevation changes
• Self-flushing to reduce clogging

 

Non-Pressure Compensating Emitters

• The output will vary with changes in pressure and elevation
• Less expensive than pressure compensating emitters
• Recommended pressure: 15-20 psi

Tutorial: Chosing The Right Drip Emitter

Is a filter required?

While a filter is not required, it is highly recommended. Even the cleanest water has small particles in it that can clog drip emitters. Micro sprays are especially susceptible to clogging as the orifices in micro spray components are especially small. Debris can enter a municipal water supply if a mainline breaks or when there is new construction in the area. Well or lake water should always be filtered. Without a filter, you may need to manually take apart emitters to clean them and remove debris that would have been caught by an inexpensive filter. Compare and buy filters.

Is all 1/2" poly tubing (drip mainline) the same?

The short answer is no. Poly tubing may be called “1/2 inch” by manufacturers and retailers but if you look closely you’ll find that the tubing has specific Outer Diameter (OD) and Inner Diameter (ID) dimensions.

Common OD dimensions are:

.700 inches (called “700") Black fittings
.620 inches (called “620”)  Green-ringed fittings
.710 inches (called “710”) Blue-ringed fittings
.580 inches (called “580”) Yellow-ringed fittings
.455 inches called "455") Red-ringed fittings

We carry 700 poly tubing and Compression fittings. We also carry fittings and adaptors for many of the common tubing sizes.

How far can I run the drip emitter tubing (dripperline)?

The maximum run varies with the size of the tubing and the spacing of the emitters.

Emitter Tubing Guidelines
Tubing Size & Emitter Spacing	Pressure Compensating Emitters?	Max psi	Max Run per branch	Max Run Total           (1/4" is fed from 1/2" mainline)
1/4" Tubing - 6" spacing 1/2 gal/hr	No	30	19 ft	200 ft
1/4" Tubing - 12" spacing 1/2 gal/hr	No	30	33 ft	400 ft
1/2" Tubing - 12" spacing 1/2 gal/hr	Yes	50*		450 ft
1/2" Tubing - 18" spacing 1/2 gal/hr	Yes	50*		500 ft
1/2" Tubing - 18" spacing 1 gal/hr	Yes	50*		350 ft
* We recommend operating at 20 - 30 psi

How do I add on to my existing drip system?

We have a great selection of drip tubing coupling adapters for varying sizes of drip tubing. They are color coded. The first step is to determine the Outer Diameter (OD) of your tubing.  

Common OD dimensions are:

.700 inches (called “700") Black fittings - 700 Compression Coupler
.620 inches (called “620”) Green-ringed fittings - 700 x 620 Compression Adapter
.710 inches (called “710”) Blue-ringed fittings - 700 x 710 Compression Adapter
.580 inches (called “580”) Yellow-ringed fittings - 700 x 580 Compression Adapter
.455 inches called "455") Red-ringed fittings - 700 x 455 Compression Adapter

If you find that your existing tubing is not 700, simply add the appropriate coupling adapter to your order to go from your tubing to 700.

Can I bury my drip tubing?

We do not recommend burying drip tubing in the soil. However, a layer of mulch on top will extend the lifespan of the drip tubing. Buy Drip tubing here.

Can I combine emitters (drippers) and micro sprays on the same line?

You can combine drip emitters, adjustable drip sprayers, and drip micro sprays all on the same poly tubing (mainline) as long as your total gallon output does not exceed the flow rate available. Drip sprayers can use in excess of 30 gallons per hour so keep track of your water output when designing your drip system. For more details, check out these tutorials:

 

Choosing The Right Drip Emitter

How Many Emitters Can I Put On a Mainline?.

How do I winterize my drip system?

If you live in an area that freezes in the winter, you should drain the water from your drip system to prevent possible damage from the expansion of water as it freezes.   The best way to plan for winter is to take some preventative measures to make the job easier in the fall. Read this Winterizing tutorial for a few tips.

Coupler

Also called a coupling, it joins fitings and pipe of like size together. Couplers may be slip, threaded, barbed or compression or combination thereof.

Connecting unlike items is called “adapting”. See Adapter.

Compression Fitting

Fittings used to connect lengths of 1/2" and 3/4" drip tubing. The tubing is simply inserted into the compression fitting. Glue is not required. See also Poly Pipe.

 

Drip Irrigation

Drip irrigation is a watering method which delivers water to plants slowly at the roots. It is also known as trickle or micro-irrigation. Where typical pop-up sprinklers spray water into the air and onto plants, drip irrigation systems combine flexible poly drip tubing and drip emitters (or drippers) to both conserve water and save money.

Drip systems are not affected by wind and will greatly reduce evaporation and runoff common with traditional irrigation systems. Drip irrigation is the perfect solution for raised beds, vegetable gardens, and potted plants.  See also Emitter, Barbed Fitting, and Poly Pipe.

Emitter

Also called a dripper, an emitter distributes water droplets at a specified flow rate when used as part of a drip irrigation system. Emitters come in a variety sizes, styles, and flow rates. They have barbed or threaded bases. Barbed ends are either poked into 1/2" drip tubing or inserted into the end of 1/4" tubing. Threaded bases are screwed into micro tubing stakes and risers.

Drip Emitter Tubing  comes with emitters pre-inserted in the tubing. It can be purchased in both 1/2" and 1/4" sizes with emitters spaced from 6 inch to 3 foot intervals.

Inline Emitters  are use to create custom emitter tubing when used with 1/4" solid drip tubing.

Pressure Compensating Emitters distribute a consistent flow rate regardless of fluctuations in pressure.

Non-Pressure-Compensating Emitters will distribute varying flow rates as pressure fluctuates with elevation changes.

Staked Emitters sit on a spike and may distribute water in a spray or stream.

Multi-Outlet Emitters can be installed onto existing sprinkler rises as part of a sprinkler retrofit project. 1/4" tubing is installed on the emitter outlets and run to individual plants.

Fittings

The common name for parts that connects irrigation parts and pipe. These include elbows, tees, couplers, crosses, male adapters, female adapters, swivel adapters, control valves, reducers, bushings, street elbows. They may be threaded, slip, barbed, compression, or a combination thereof.

Filter

A filter contains a screen that is designed to remove particles from irrigation systems. Filters are critical components in a drip irrigation system. Drip emitters may clog if proper filtration is not provided. Typical screen mesh is 120, 150, and 200 mesh. The greater the number, the smaller the openings in the screen. 200 mesh is recommended for foggers (misters).

Pressure Regulator

A device that lowers water pressure on the downstream side and maintains a constant operating pressure. Regulators are commonly used in drip irrigation applications as drip tubing and fittings are usually rated to operate at pressures lower than most household water systems. Always install a regulator after a valve and filter. They are not designed to be operated under constant pressure.

Pressure Compensating

Pressure Compensating Emitters. The output will not vary with changes in elevation and pressure. They deliver the stated gph (gallons per hour) even if pressures range from 10-50 psi. These emitters are best used with elevation changes. They are self-flushing to reduce clogging. See also Emitter, Non-Pressure-Compensating.

Non-Pressure-Compensating

Non-Pressure-Compensating Emitters. The output will vary with changes in elevation and pressure. These emitters are best used where the watering zone is level. Some non-pressure-compensating emitters are used with gravity-fed drip systems. They operate best at lower pressures. Recommended Pressure for most non-p-c emitters: 15-20 psi. See also Emitter, Pressure Compensating.
